This changes the RPC server to ignore methods using *context.Context as parameter
and *error as return value type. Methods with such types would crash the server when
called.

This change fixes a minor flaw in the check for ipc endpoint length. The max_path_size is the max path that an ipc endpoint can have, which is 208. However, that size concerns the null-terminated pathname, so we need to account for an extra null-character too.

Here we add special handling for sending an error response when the write timeout of the
HTTP server is just about to expire. This is surprisingly difficult to get right, since is
must be ensured that all output is fully flushed in time, which needs support from
multiple levels of the RPC handler stack:
The timeout response can't use chunked transfer-encoding because there is no way to write
the final terminating chunk. net/http writes it when the topmost handler returns, but the
timeout will already be over by the time that happens. We decided to disable chunked
encoding by setting content-length explicitly.
Gzip compression must also be disabled for timeout responses because we don't know the
true content-length before compressing all output, i.e. compression would reintroduce
chunked transfer-encoding.

rpc: fix connection tracking in Server
When upgrading to mapset/v2 with generics, the set element type used in
rpc.Server had to be changed to *ServerCodec because ServerCodec is not
'comparable'. While the distinction is technically correct, we know all
possible ServerCodec types, and all of them are comparable. So just use
a map instead.

This changes the error code returned by the RPC server in certain situations:
- handler panic: code -32603
- result marshaling error: code -32603
- attempt to subscribe via HTTP: code -32001
In all of the above cases, the server previously returned the default error
code -32000.

The JSON-RPC spec requires the "version" field to be exactly "2.0",
so we should verify that. This change is not backwards-compatible with
sloppy client implementations, but I decided to go ahead with it anyway
because the failure will be caught via the returned error.

When talking to an HTTP2 server, there are situations where it needs to
"rewind" the Request.Body. To allow this, we have to set up the Request.GetBody
function to return a brand new instance of the body.
If not set, we can end up with the following error:
http2: Transport: cannot retry err [http2: Transport received Server's graceful shutdown GOAWAY] after Request.Body was written; define Request.GetBody to avoid this error

This avoids quadratic time complexity in the lookup of the batch element
corresponding to an RPC response. Unfortunately, the new approach
requires additional memory for the mapping from ID to index.

This fixes a rare issue where the client subscription forwarding loop
would attempt send on the subscription's channel after Unsubscribe has
returned, leading to a panic if the subscription channel was already
closed by the user. Example:
sub, _ := client.Subscribe(..., channel, ...)
sub.Unsubscribe()
close(channel)
The race occurred because Unsubscribe called quitWithServer to tell the
forwarding loop to stop sending on sub.channel, but did not wait for the
loop to actually come down. This is fixed by adding an additional channel
to track the shutdown, on which Unsubscribe now waits.
Fixes#22322

Notifier tracks whether subscription are 'active'. A subscription
becomes active when the subscription ID has been sent to the client. If
the client sends notifications in the request handler before the
subscription becomes active they are dropped. The tests tried to work
around this problem by always waiting 5s before sending the first
notification.
Fix it by buffering notifications until the subscription becomes active.
This speeds up all subscription tests.
Also fix TestSubscriptionMultipleNamespaces to wait for three messages
per subscription instead of six. The test now finishes just after all
notifications have been received and doesn't hit the 30s timeout anymore.
