check ScheduledCompactKeyName and FinishedCompactKeyName
before writing hash to hashstore. If they do not match, then it means this compaction has once been interrupted and its hash value is invalid. In such cases, we won't write the hash values to the hashstore, and avoids the incorrect corruption alarm.

Progress notifications requested using ProgressRequest were sent
directly using the ctrlStream, which means that they could race
against watch responses in the watchStream.
This would especially happen when the stream was not synced - e.g. if
you requested a progress notification on a freshly created unsynced
watcher, the notification would typically arrive indicating a revision
for which not all watch responses had been sent.
This changes the behaviour so that v3rpc always goes through the watch
stream, using a new RequestProgressAll function that closely matches
the behaviour of the v3rpc code - i.e.
1. Generate a message with WatchId -1, indicating the revision for
*all* watchers in the stream
2. Guarantee that a response is (eventually) sent
The latter might require us to defer the response until all watchers
are synced, which is likely as it should be. Note that we do *not*
guarantee that the number of progress notifications matches the number
of requests, only that eventually at least one gets sent.

Problem: during restore in watchableStore.Restore, synced watchers are moved to unsynced.
minRev will be behind since it's not updated when watcher stays synced.
Solution: update minRev

The original testcase uses `return` statement which skips `restore`
case. It's aimed to enable `restore` testcase.

After setting the ComparionSleepInterval, we can use time.Ticker
instead of time.After to optimize the scheduleComparison(),
otherwise it will fail in the 'TestStoreCompact(t)' test.

We need to return io.ErrUnexpectedEOF in the error chain, so that
etcdserver can repair it automatically.

Previously etcdservers depends on raft/raftpb/raft.proto directly.
After moving raft to a separate repo, we need to add raft to the
tools/mod, and get raft included in the -I protc flags.

`unsafeCommit` is called by both `(*batchTxBuffered) commit` and
`(*backend) defrag`. When users perform the defragmentation
operation, etcd doesn't update the consistent index. If etcd
crashes(e.g. panicking) in the process for whatever reason, then
etcd replays the WAL entries starting from the latest snapshot,
accordingly it may re-apply entries which might have already been
applied, eventually the revision isn't consistent with other members.

When a key-value store corruption check happens immediately after a
compaction, the revision at which the key-value store hash is computed,
is the compacted revision itself.
In that case, the hash computation logic was incorrect because it
returned an ErrCompacted error; this error should instead be returned when
the revision at which the key-value store is hashed, is strictly lower
than the compacted revision.

A WAL object was closed by defer, however the WAL was rewritten afterwards,
so defer closed already closed WAL but not the new one. It caused a data
race between writing file and cleaning up a temporary test directory,
which led to a non-deterministic bug.
