Also tidied up some of Richard's code (I don't think he uses the compiler
flags -g -Wall -Wshadow -Wstrict-prototypes -Wpointer-arith -Wcast-qual like
I do :-) :-).

be traversals being attempted. Yes, this was from bitter experience (and
an out of control server :-). Also allow callers to break out of a tdb_chainlock
with sigalarm if desired.

a separate tdb per printer, but only keeps (currently one) tdb open at
a time (although this is easily changed by changing a #define). Needs
scalability testing with large numbers of printers now....

just returning. I don't think this would leak at the moment, but it's
an accident waiting to happen.
(This used to be commit fe901ec194d1b8ef94386b097e72508075eb8a54)
as it was, and add tdb_open_ex() which takes a log callback. I guess
this makes more sense since it's a public interface.
(This used to be commit 391a65395e6cdc0300f81eb1072a3366cacd1203)
- tdb_open api changed so that you now pass an error handling
callback when opening the file, so that errors detected during
opening have somewhere to go. (All calls from the body of Samba to
this function go through a wrapper in tdbutil, which has been
updated.)
- Clean up logic for deciding how to open tdb. Emit log messages if
something goes wrong (e.g. bad magic.)
- tdbtool now logs errors to stderr.

database, but no underlying system call sets errno.
The particular case I had was a mangled .tdb, but there are others.
For this one, set EIO. It's a shame Unix messages aren't more
detailed -- "bad data format" would be better.
(This used to be commit 5630a988be05c21b60aba6304d4aaadce6024817)
means that a read-write opener and a read-only opener are using different
locking mechanisms - this needs to be addressed, but it's hard as the
read-write opener using the spinlocks is usually first, so there's no
way to force them to change down to the fcntl method.
Read only access is less important anyway and can never corrupt the
tdb anyway, so errors in read-only record reads are more tolerable.

change these timestamp settings without good reason.
Remove CLEAR_IF_FIRST flag is tdb is read-only.

unlock are explicitly non-blocking. I will add a comment to this effect later.

(This used to be commit e4b41a8f31729dfec92c4cb1f8b4759446cac0ff)
map_ptr not neccessarily set to NULL if no mmap, secondly, iterating
through a tdb was using SETLK, instead of SETLKW - would almost never
fail with mmap as the time holding the lock was so short, but was
easily seen with read/write. One finaly bug needs tracking down w.r.t.
traversal......

Ok - now we're no longer trying to reach a silly 1k loc target,
change the formatting to be *readable* - eg.
change if (x) y else z to be :
if (x)
y
else
z
and other compact sillyness. Oh look - when I did this I found
some areas where we *WEREN'T CHECKING SYSTEM CALL ERROR RETURNS !!!!*
CompSci 101 guys....... :-).
