ctdb wants a quick way to detect corrupt tdbs; particularly, tdbs with
loops in their hash chains. tdb_check() provides this.

We no longer use swig for pytdb, so there is no need for swig make
rules. Also pytdb.c header should be updated.

With the ctdb checkin dde9f3f006 tdb optimized out write lock checks for
write-enabled transaction. Sadly, this also removed the possibility to ever
remove dead records left over from tdb_delete calls within a transaction.
Tridge, please check this! Did dde9f3f006 have any reason beyond performance
optimizations?
Thanks,
Volker

tdbbackup was originally written before we had transactions, and it
attempted to use its own fsync() calls to make it safe. Now that we
have transactions we can do it in a much safer (and faster!) fashion

It was a regrettable hack which I used to reduce line count in tdb; in fact it caused confusion as can be seen in this patch.
In particular, ecode now needs to be set before TDB_LOG anyway, and having it exposed in
the header is useless (the struct tdb_context isn't defined, so it's doubly useless).
Also, we should never set errno, as io.c was doing.

When TDB_TRACE is defined (in tdb_private.h), verbose tracing of tdb operations is enabled.
This can be replayed using "replay_trace" from http://ccan.ozlabs.org/info/tdb.
The majority of this patch comes from moving internal functions to _<funcname> to
avoid double-tracing. There should be no additional overhead for the normal (!TDB_TRACE)
case.
Note that the verbose traces compress really well with rzip.

There was a race condition that caused the torture.tdb to be left in a
state that needed recovery. The torture code thought that any message
from the tdb code was an error, so the "recovered" message, which is a
TDB_DEBUG_TRACE message, marked the run as being an error when it
isn't.

We previously only allowed a commit to happen after a prepare
commit. It is in fact safe to allow reads between a prepare and a
commit, and the s4 replication code can make use of that, so allow it.

This produces output like the output gcc produces when
invoked with the -aux-info switch.
Run like this: cat include/tdb.h | ./script/mksigs.pl
This simple parser is probably too coarse to handle all
possible header files, but it treats tdb.h correctly...

On systems with 32 bit offsets, expansion and fcntl locking on these records
will fail anyway. SAMBA already does '#define _FILE_OFFSET_BITS 64' in
config.h (on my 32-bit x86 Linux system at least) to get 64 bit file offsets.
