WIP: KUDU-2509 fix use-after-free in case of WAL replay error
Fixed use-after-free mistake in case of an failure to apply commit
or replicate message from WAL while bootstrapping a tablet. The
use-after-free condition happened in some rare cases.
In addition, reduced number of memory allocations while reading WAL
entries from disk during tablet bootstrap. Also did other unsorted
minor changes in tablet_bootstrap.cc and around like replacing
gscoped_ptr with unique_ptr, etc.
WIP: need to add good repro scenario for the bug, which does not seem to
be very easy.
