It appears that wafsamba's configure() defines _GNU_SOURCE
unconditionally, so checking _GNU_SOURCE isn't enough to know if this
variable is available.
For example, it isn't available on AIX with the xlc compiler:
[ 6/10] Compiling lib/replace/replace.c
...
"../../lib/replace/replace.c", line 991.16: 1506-045 (S) Undeclared identifier program_invocation_short_name.
Instead, add a configure check for program_invocation_short_name and
use it.

tdb->max_dead_records is "int", as is the corresponding parameter to
tdb_set_max_dead(). Not that a signed variable makes any sense, but
this is old code and tdb_set_max_dead() is a public API which we
should not change for this.

Before this patch we had 3 loops walking a hash chain to delete
records:
tdb_do_delete() to find the predecessor of the record that was to be
deleted. tdb_count_dead(), the name says it all and tdb_purge_dead()
to give back all dead records from a chain to the freelist.
This patch introduces tdb_trim_dead that walks a hash chain just
once. While it does so it counts the number of dead records, and all
records beyond tdb->max_dead_records are moved to the freelist.
Normal record deletion now works by always marking a record as dead in
step 1 and then calling tdb_trim_dead. This is made safe against
circular chains by doing the slow chain walk only in the case when we
did not delete a dead record during our walk.
It changes our dynamics a bit:
When deleting a record with non-zero max_dead_records, now we always
leave that number of records around when deleting, doing a blocking
lock on the freelist when we found too many dead records.
Previously when exceeding max_dead_records we wiped all dead records
to start accumulating them from scratch, assuming we could lock the
freelist in a nonblocking fashion.
The net effect for an uncontended freelist is the same: In
tdb_allocate() we still completely hand over all dead records to the
freelist when we could lock it, it just happens later than without
this patch.
This means for a lightly loaded system we will potentially leave more
dead records around in databases like locking.tdb. However, on a
heavily loaded system we become more predictable: If the freelist is
so heavily contended that across many deletes we can't get hold of it,
previously we accumulated more dead records than max_dead_records
would allow. This is a really lowlevel tradeoff that is likely hard to
measure, but to me becoming more deterministic without sacrificing too
much parallelism (we keep more dead records around) is worth trying.

The next commit will change the handling of dead records, removing the
"tdb_do_delete" function. As traverses should not happen in normal
operations, dead records from them should be rare, and relying on
traverses to remove them is a very bad idea IMHO.

Right now we don't do transactions with mutexed tdbs. tdbtorture -m
locks up. I haven't really investigated why that is the case. The lockup
confused me quite a bit until I figured out it works fine as long as it
does not do transactions, which is all we need right now.
