Subject: [PATCH 004/107] cmd/ethkey: fix formatting, review nits (#15807)

This commit:

- Adds a --msgfile option to read the message to sign from a file
  instead of command line argument.
- Adds a unit test for signing subcommands.
- Removes some weird whitespace in the code.

Subject: [PATCH 006/107] all: update generated code (#15808)

* core/types, core/vm, eth, tests: regenerate gencodec files

* Makefile: update devtools target

Install protoc-gen-go and print reminders about npm, solc and protoc.
Also switch to github.com/kevinburke/go-bindata because it's more
maintained.

* contracts/ens: update contracts and regenerate with solidity v0.4.19

The newer upstream version of the FIFSRegistrar contract doesn't set the
resolver anymore. The resolver is now deployed separately.

* contracts/release: regenerate with solidity v0.4.19

* contracts/chequebook: fix fallback and regenerate with solidity v0.4.19

The contract didn't have a fallback function, payments would be rejected
when compiled with newer solidity. References to 'mortal' and 'owned'
use the local file system so we can compile without network access.

* p2p/discv5: regenerate with recent stringer

* cmd/faucet: regenerate

* dashboard: regenerate

* eth/tracers: regenerate

* internal/jsre/deps: regenerate

* dashboard: avoid sed -i because it's not portable

* accounts/usbwallet/internal/trezor: fix go generate warnings

Subject: [PATCH 046/107] p2p, p2p/discover, p2p/discv5: implement UDP port
 sharing (#15200)

This commit affects p2p/discv5 "topic discovery" by running it on
the same UDP port where the old discovery works. This is realized
by giving an "unhandled" packet channel to the old v4 discovery
packet handler where all invalid packets are sent. These packets
are then processed by v5. v5 packets are always invalid when
interpreted by v4 and vice versa. This is ensured by adding one
to the first byte of the packet hash in v5 packets.

DiscoveryV5Bootnodes is also changed to point to new bootnodes
that are implementing the changed packet format with modified
hash. Existing and new v5 bootnodes are both running on different
ports ATM.

Subject: [PATCH 048/107] consensus/ethash: improve cache/dataset handling
 (#15864)

* consensus/ethash: add maxEpoch constant

* consensus/ethash: improve cache/dataset handling

There are two fixes in this commit:

Unmap the memory through a finalizer like the libethash wrapper did. The
release logic was incorrect and freed the memory while it was being
used, leading to crashes like in #14495 or #14943.

Track caches and datasets using simplelru instead of reinventing LRU
logic. This should make it easier to see whether it's correct.

* consensus/ethash: restore 'future item' logic in lru

* consensus/ethash: use mmap even in test mode

This makes it possible to shorten the time taken for TestCacheFileEvict.

* consensus/ethash: shuffle func calc*Size comments around

* consensus/ethash: ensure future cache/dataset is in the lru cache

* consensus/ethash: add issue link to the new test

* consensus/ethash: fix vet

* consensus/ethash: fix test

* consensus: tiny issue + nitpick fixes

+### Added
+
+### Fixed
+
+### Changed
+
+### Deprecated
+
+## [0.8.0]
+
+### Added
+- Added partial `getrusage` support for Windows to retrieve system CPU time and user CPU time. #95
+- Added full `getrusage` support for Unix. #95
+
+## [0.7.0]
+
+### Added
+- Added method stubs for process handling for operating system that are not supported
+  by gosigar. All methods return `ErrNotImplemented` on such systems. #88
+
+### Fixed
+- Fix freebsd build by using the common version of Get(pid). #91
+
+### Changed
+- Fixed issues in cgroup package by adding missing error checks and closing
+  file handles. #92
+
+## [0.6.0]
+
+### Added
+- Added method stubs to enable compilation for operating systems that are not
+  supported by gosigar. All methods return `ErrNotImplemented` on these unsupported
+  operating systems. #83
+- FreeBSD returns `ErrNotImplemented` for `ProcTime.Get`. #83
+
+### Changed
+- OpenBSD returns `ErrNotImplemented` for `ProcTime.Get` instead of `nil`. #83
+- Fixed incorrect `Mem.Used` calculation under linux. #82
+- Fixed `ProcState` on Linux and FreeBSD when process names contain parentheses. #81
+
+### Removed
+- Remove NetBSD build from sigar_unix.go as it is not supported by gosigar. #83
+
+## [0.5.0]
+
+### Changed
+- Fixed Trim environment variables when comparing values in the test suite. #79
+- Make `kern_procargs` more robust under darwin when we cannot retrieve
+  all the information about a process. #78
+
+## [0.4.0]
+
+### Changed
+- Fixed Windows issue that caused a hang during `init()` if WMI wasn't ready. #74
+
+## [0.3.0]
+
+### Added
+- Read `MemAvailable` value for kernel 3.14+ #71
+
+## [0.2.0]
+
+### Added
+- Added `ErrCgroupsMissing` to indicate that /proc/cgroups is missing which is
+  an indicator that cgroups were disabled at compile time. #64
+
+### Changed
+- Changed `cgroup.SupportedSubsystems()` to honor the "enabled" column in the
+  /proc/cgroups file. #64
+
+## [0.1.0]
+
+### Added
+- Added `CpuList` implementation for Windows that returns CPU timing information
+  on a per CPU basis. #55
+- Added `Uptime` implementation for Windows. #55
+- Added `Swap` implementation for Windows based on page file metrics. #55
+- Added support to `github.com/gosigar/sys/windows` for querying and enabling
+  privileges in a process token.
+- Added utility code for interfacing with linux NETLINK_INET_DIAG. #60
+- Added `ProcEnv` for getting a process's environment variables. #61
+
+### Changed
+- Changed several `OpenProcess` calls on Windows to request the lowest possible
+  access privileges. #50
+- Removed cgo usage from Windows code.
+- Added OS version checks to `ProcArgs.Get` on Windows because the
+  `Win32_Process` WMI query is not available prior to Windows vista. On XP and
+  Windows 2003, this method returns `ErrNotImplemented`. #55
+
+### Fixed
+- Fixed value of `Mem.ActualFree` and `Mem.ActualUsed` on Windows. #49
+- Fixed `ProcTime.StartTime` on Windows to report value in milliseconds since
+  Unix epoch. #51
+- Fixed `ProcStatus.PPID` value is wrong on Windows. #55
+- Fixed `ProcStatus.Username` error on Windows XP #56

+# Go sigar [![Build Status](https://travis-ci.org/elastic/gosigar.svg?branch=master)](https://travis-ci.org/elastic/gosigar) [![Build status](https://ci.appveyor.com/api/projects/status/4yh6sa7u97ek5uib/branch/master?svg=true)](https://ci.appveyor.com/project/elastic-beats/gosigar/branch/master)
+
+
+## Overview
+
+Go sigar is a golang implementation of the
+[sigar API](https://github.com/hyperic/sigar).  The Go version of
+sigar has a very similar interface, but is being written from scratch
+in pure go/cgo, rather than cgo bindings for libsigar.
+
+## Test drive
+
+    $ go get github.com/elastic/gosigar
+    $ cd $GOPATH/src/github.com/elastic/gosigar/examples/ps
+    $ go build
+    $ ./ps
+
+## Supported platforms
+
+The features vary by operating system.

+## OS Specific Notes
+
+### FreeBSD
+
+Mount both `linprocfs` and `procfs` for compatability. Consider adding these
+mounts to your `/etc/fstab` file so they are mounted automatically at boot.
+
+```
+sudo mount -t procfs proc /proc
+sudo mkdir -p /compat/linux/proc
+sudo mount -t linprocfs /dev/null /compat/linux/proc
+```

+The change to provide building on all platforms is a new feature. The increase in minor version reflects that and allows those who wish to stay on 1.0.x to continue to do so. Support for 1.0.x will be limited to bug fixes.
+
+ * Move GUID out of variables.go into its own file to make new documentation available.
+ * Move OleError out of ole.go into its own file to make new documentation available.
+ * Add documentation to utility functions.
+ * Add documentation to variant receiver functions.
+ * Add documentation to ole structures.
+ * Make variant available to other systems outside of Windows.
+ * Make OLE structures available to other systems outside of Windows.
+
+## New Features
+
+ * Library should now be built on all platforms supported by Go. Library will NOOP on any platform that is not Windows.
+ * More functions are now documented and available on godoc.org.
+
+# Version 1.0.1
+
+ 1. Fix package references from repository location change.
+
+# Version 1.0.0
+
+This version is stable enough for use. The COM API is still incomplete, but provides enough functionality for accessing COM servers using IDispatch interface.
+
+There is no changelog for this version. Check commits for history.

+#Go OLE
+
+[![Build status](https://ci.appveyor.com/api/projects/status/qr0u2sf7q43us9fj?svg=true)](https://ci.appveyor.com/project/jacobsantos/go-ole-jgs28)
+[![Build Status](https://travis-ci.org/go-ole/go-ole.svg?branch=master)](https://travis-ci.org/go-ole/go-ole)
+[![GoDoc](https://godoc.org/github.com/go-ole/go-ole?status.svg)](https://godoc.org/github.com/go-ole/go-ole)
+
+Go bindings for Windows COM using shared libraries instead of cgo.
+
+By Yasuhiro Matsumoto.
+
+## Install
+
+To experiment with go-ole, you can just compile and run the example program:
+
+```
+go get github.com/go-ole/go-ole
+cd /path/to/go-ole/
+go test
+
+cd /path/to/go-ole/example/excel
+go run excel.go
+```
+
+## Continuous Integration
+
+Continuous integration configuration has been added for both Travis-CI and AppVeyor. You will have to add these to your own account for your fork in order for it to run.
+
+**Travis-CI**
+
+Travis-CI was added to check builds on Linux to ensure that `go get` works when cross building. Currently, Travis-CI is not used to test cross-building, but this may be changed in the future. It is also not currently possible to test the library on Linux, since COM API is specific to Windows and it is not currently possible to run a COM server on Linux or even connect to a remote COM server.
+
+**AppVeyor**
+
+AppVeyor is used to build on Windows using the (in-development) test COM server. It is currently only used to test the build and ensure that the code works on Windows. It will be used to register a COM server and then run the test cases based on the test COM server.
+
+The tests currently do run and do pass and this should be maintained with commits.
+
+##Versioning
+
+Go OLE uses [semantic versioning](http://semver.org) for version numbers, which is similar to the version contract of the Go language. Which means that the major version will always maintain backwards compatibility with minor versions. Minor versions will only add new additions and changes. Fixes will always be in patch. 
+
+This contract should allow you to upgrade to new minor and patch versions without breakage or modifications to your existing code. Leave a ticket, if there is breakage, so that it could be fixed.

+
+Package errors provides simple error handling primitives.
+
+`go get github.com/pkg/errors`
+
+The traditional error handling idiom in Go is roughly akin to
+```go
+if err != nil {
+        return err
+}
+```
+which applied recursively up the call stack results in error reports without context or debugging information. The errors package allows programmers to add context to the failure path in their code in a way that does not destroy the original value of the error.
+
+## Adding context to an error
+
+The errors.Wrap function returns a new error that adds context to the original error. For example
+```go
+_, err := ioutil.ReadAll(r)
+if err != nil {
+        return errors.Wrap(err, "read failed")
+}
+```
+## Retrieving the cause of an error
+
+Using `errors.Wrap` constructs a stack of errors, adding context to the preceding error. Depending on the nature of the error it may be necessary to reverse the operation of errors.Wrap to retrieve the original error for inspection. Any error value which implements this interface can be inspected by `errors.Cause`.
+```go
+type causer interface {
+        Cause() error
+}
+```
+`errors.Cause` will recursively retrieve the topmost error which does not implement `causer`, which is assumed to be the original cause. For example:
+```go
+switch err := errors.Cause(err).(type) {
+case *MyError:
+        // handle specifically
+default:
+        // unknown error
+}
+```
+
+[Read the package documentation for more information](https://godoc.org/github.com/pkg/errors).

Subject: [PATCH 074/107] rpc: Support specifying HTTP client in RPC dialing
 (#15836)

* rpc: Support specifying HTTP client in RPC dialing

Adds a minimal interface that captures http.Client and adds a new method
rpc.DialHTTPClient that takes a client using that interface. The existing
rpc.DialHTTP method is then alternatively implemented by using the new
rpc.DialHTTPClient method provided with a standard *http.Client.

* rpc: fix minor doc typos

Subject: [PATCH 083/107] whisper: remove linter warnings (#15972)

* whisper: fixes warnings from the code linter

* whisper: more non-API-breaking changes

The remaining lint errors are because of auto-generated
files and one is because an exported function has a non-
exported return type. Changing this would break the API,
and will be part of another commit for easier reversal.

* whisper: un-export NewSentMessage to please the linter

This is an API change, which is why it's in its own commit.
This change was initiated after the linter complained that
the returned type wasn't exported. I chose to un-export
the function instead of exporting the type, because that
type is an implementation detail that I would like to
change in the near future to make the code more
readable and with an increased coverage.

* whisper: update gencodec output after upgrading it to new lint standards
