Precompute log header - reduce msg formatting overhead
More direct use of log buffers - minimize copying
Multiple lines per send
  supported by default in syslog-ng
  not default in rsyslog

Don't need op->o_hr_time, just use o_tincr, that's what it
was intended for anyway. Use "etime=" like other products do.
Simplify ifdefs. Use gettimeofday, it's always available now.

Also add ldap_pvt_gettimeofday() to
emulate gettimeofday on Windows

Wrong function signature

No effect on current code.

...early enough that txn state is left unchanged.

Move the check to the end of txn startup.  Catches env
breakage which happens while the new txn waits for a lock.

* Add MDB_TXN_FINISHED, MDB_TXN_HAS_CHILD, MDB_TXN_BLOCKED.
* Clear mt_numdbs in writers, for TXN_DBI_EXIST() to catch.
  We already do in readers.

Side effects:
* Clean txn up a bit even before freeing it.
* Tweak DEBUG output at txn end. Add DEBUG after commit(writer).

MDB_DBI_CHANGED(,MAIN_DBI) is never true.

mt_env is always set.
Commit(mt_child) resets mt_child, so parent need not.
