r19402: - use the new tdb_lockall_read() to make ldb_search() more efficient,
by avoiding chain locks on each tdb_fetch() within the search
- use the tdb_get_seqnum() call to avoid re-reading the @BASEINFO
record when it hasn't changed.
These speed up the LOCAL-DBSPEED test for ldb from 7k ops/sec to a bit
over 11k ops/sec
(This used to be commit 1347ad254eb8cd12ce22a5a2a37bec0a0ac8dbf1)
