ccf477d12b restrict the max size of each WAL entry to the remaining size of the file 
Currently the max size of each WAL entry is hard coded as 10MB. If users
set a value > 10MB for the flag --max-request-bytes, then etcd may run
into a situation that it successfully processes a big request, but fails
to decode it when replaying the WAL file on startup.

On the other hand, we can't just remove the limitation, because if a
WAL entry is somehow corrupted, and its recByte is a huge value, then
etcd may run out of memory. So the solution is to restrict the max size
of each WAL entry as a dynamic value, which is the remaining size of
the WAL file.
