* Improve package documentation.
* `processAttestations`: Improve logging.
* Add `Benchmark_checkSurroundVotes` benchmark.
* Implement `saveChunksToDisk` as remplacement of `saveUpdatedChunks`.
The idea is to open only on DB transaction for all validator chunk indexes instead of
one DB transaction per validator chunk index.
It saves the overhead due to transaction start/stop of the DB.
Result of `Benchmark_checkSurroundVotes`:
- Before this commit: 133 seconds
- After this commit: 5.05 seconds
* `LoadSlasherChunks` and `SaveSlasherChunks`: Batch.
* `loadChunks` ==> `loadChunksFromDisk`
* `updatedChunkByChunkIndex`: Don't update if `latestEpochWritten == currentEpoch `.
* `updatedChunkByChunkIndex`: Load all needed chunks once.
* `latestEpochWritten` ==> `latestEpochUpdated`.
* `checkSurroundVotes`: Dump to disk at most every `25_600` chunks.
* `SaveAttestationRecordsForValidators`: Batch.
* `batchSize`: Use as package const and add comment.
* pending broadcast err if missing blobs and 0 peers
* compute request first for len check

* `getChunk` ==> `getChunkFromDatabase`.
* `loadChunks`: Rename variables.
* `Update`: Use explicit arguments.
* `detect_attestations.go`: Reduce abstraction layers.
* `loadAndUpdateChunks`: Change arguments order.
* `updatedChunkByChunkIndex`: Update all known validators in the chunk.
* `LastEpochWrittenForValidators`: Avoid avoidable `for`loop.
* `chunks.go`: Ensure implementations respect the interface.
* `LastEpochWrittenForValidators`: Stop considering lack of epoch as genesis epoch.
* `updatedChunkByChunkIndex`: Don't update latest updated epoch.
And add a bunch of tests.
* Improve slasher cold boot duration.
Before this commit, on a slasher cold boot (aka, without any db),
the `updatedChunkByChunkIndex` function looped for all validators
AND for all epochs between the genesis epoch and the current epoch.
This could take several dozen of minutes, and it is useless since the
min/max spans are actually a circular buffer with a limited lenght.
Cells of min/max spans can be overwritten (with the same value)
plenty of times.
After this commit, the `updatedChunkByChunkIndex` function loops
for all validators AND AT most 'historyLength' lenght.
Every cell of min/max spans are written AT MOST once.
Time needed for slasher boot goes from `O(nm)` to "only" `O(m)`, where:
- `n` is the number of epochs since the genesis.
- `m` is the number of validators.
* First take at updating everything to v5
* Patch gRPC gateway to use prysm v5
Fix patch

* `LastEpochWrittenForValidators`: Use golang if.
* `SaveLastEpochsWrittenForValidators`: Refactor.
* `SaveLastEpochsWrittenForValidators`: Fix when `epochByValIndex` > `batchSize`.
Before this commit, `TestStore_LastEpochWrittenForValidators` works if `validatorsCount <= 10000`
and stops working if `validatorsCount > 10000`.
* Slasher: Detect surrounded votes in multiple batches.
