* Add CLI flags to config LevelDB table/total sizes
I wired up CLI flags to allow configuring LevelDB table and total sizes:
- `--leveldb.compaction.table.size`, LevelDB SSTable file size factor in MiB (default: 2)
- `--leveldb.compaction.table.multiplier`, multiplier on LevelDB SSTable file size (default: 1)
- `--leveldb.compaction.total.size`, total size factor in MiB of LevelDB levels (default: 10)
- `--leveldb.compaction.total.multiplier`, multiplier on LevelDB total level size (default: 10)
N.B. that the default values for these configs are exactly the same as
before this changset and so Bor behavior should not change unless these
flags are deliberately overridden. Bor/Geth inherited the default values
from [the `goleveldb`
defaults](126854af5e/leveldb/opt/options.go).
We (Alchemy) found it necessary to override these configs as follows to
keep Bor archive nodes tracking the canonical chain:
- `--leveldb.compaction.table.size=4`
- `--leveldb.compaction.total.size=20`
These overrides double the size of LevelDB SSTable files (2 MiB -> 4
MiB) and also the total amount of data in each level (100 MiB -> 200
MiB, 1,000 MiB -> 2,000 MiB, etc.). The idea is to have LevelDB read and
write data in larger chunks while keeping the proportional frequency of
compaction operations the same as in the original defaults defined by
Dean and Ghemawat.
Without these overrides we found that our archive nodes would tend to
fall into a "LevelDB compaction loop of death" where the incoming stream
of blockchain data could not be flowed into LevelDB's structure quickly
enough, resulting in the node blocking writes for long periods of time
while LevelDB's single-threaded compaction organized the data. Over
time the nodes would fall farther and farther behind the canonical chain
head, metaphorically dying a slow node's death.
These configs can be changed on existing node databases (resyncing is
not necessary). LevelDB appears to work correctly with SSTable files of
different sizes. Note that the database does not undergo any sort of
migration when changing these configs. Only newly-written files (due to
new data or compaction) are affected by these configs.

* cmd/utils, node: switch to Pebble as the default db if none exists
* node: fall back to LevelDB on platforms not supporting Pebble
* core/rawdb, node: default to Pebble at the node level
* cmd/geth: fix some tests explicitly using leveldb
* ethdb/pebble: allow double closes, makes tests simpler
This change prints out more information about the problem, in the case where geth detects a gap between leveldb and ancients, so we can determine more exactly where the gap is (what the first missing is). Also prints out more metadata.

This PR ports a few changes from PBSS:
- Fix the snapshot generator waiter in case the generation is not even initialized
- Refactor db inspector for ancient store
Previously freezer has only been used for storing ancient chain data, while obviously it can be used more. This PR unties the chain data and freezer, keep the minimal freezer structure and move all other logic (like incrementally freezing block data) into a separate structure called ChainFreezer.
This PR also extends the database interface by adding a new ancient store function AncientDatadir which can return the root directory of ancient store. The ancient root directory can be used when we want to open some other ancient-stores (e.g. reverse diff freezer).

This PR offers two more database sub commands for exporting and importing data.
Two exporters are implemented: preimage and snapshot data respectively.
The import command is generic, it can take any data export and import into leveldb.
The data format has a 'magic' for disambiguation, and a version field for future compatibility.
This PR adds a new accessor method to the freezer database. This new view offers a consistent interface, guaranteeing that all individual tables (headers, bodies etc) are all on the same number, and that this number is not changes (added/truncated) while the operation is performing.
This change is a rewrite of the freezer code.
When writing ancient chain data to the freezer, the previous version first encoded each
individual item to a temporary buffer, then wrote the buffer. For small item sizes (for
example, in the block hash freezer table), this strategy causes a lot of system calls for
writing tiny chunks of data. It also allocated a lot of temporary []byte buffers.
In the new version, we instead encode multiple items into a re-useable batch buffer, which
is then written to the file all at once. This avoids performing a system call for every
inserted item.
To make the internal batching work, the ancient database API had to be changed. While
integrating this new API in BlockChain.InsertReceiptChain, additional optimizations were
also added there.
