wal: fix the unexpectedEOF error in the last wal.
...
It is safe to repair the unexpectedEOF error in the last wal. raft
will not send out message before the entry successfully comitted
into wal. Thus we can safely truncate the last entry in the wal
to repair.

wal: fix ReleaseLockTo
...
ReleaseLockTo should not release the lock on the WAL
segment that is right before the given index. When
restarting etcd, etcd needs to read from the WAL segment
that has a smaller index than the snapshot index.
The correct behavior is that ReleaseLockTo releases
the locks w is holding so that w only holds one lock
that has an index smaller than the given index.

wal: support auto-cut in wal

WAL should control the cut logic itself. We want to do falloc to
per allocate the space for a segmented wal file at the beginning
and cut it when it size reaches the limit.
