The performance of these is minimal (these days) and they can return
invalid results when used as part of applications that do not use
sys_fork().

It's fine to ignore socket wrapper here, as it doesn't deal with unix domain sockets.

We unmap the tdb on expand, the remap. But when we have INCOHERENT_MMAP
(ie. OpenBSD) and we're inside a transaction, doing the expand can mean
we need to read from the database to partially fill a transaction block.
This fails, because if mmap is incoherent we never allow accessing the
database via read/write.
The solution is not to unmap and remap until we've actually written the
padding at the end of the file.

Since we force mmap on, we don't intercept writes to the db, so we never
see it in an inconsistent state. #ifdef over the check that we should have
recovered it at least once.

fde694274e1e5a11d1473695e7ec7a97f95d39e4 made tdb_mmap return an int,
but didn't put the return 0 on the "internal db" case.

We use tdb_mkdata() to get rid of many of them from the tests, and
explicit cast_const() in a few places.
tlist_for_each() still causes a warning, but that needs to be fixed in
CCAN.

This handles incoherent mmaps for TDB2 native databases, by forcing
mmap on for such systems, just like we did for tdb1.

This comment appears in two places in the code (commit
4c6a8273c6dd3e2aeda5a63c4a62aa55bc133099 from 2001):
/*
* We must ensure the file is unmapped before doing this
* to ensure consistency with systems like OpenBSD where
* writes and mmaps are not consistent.
*/
But this doesn't help, because if one process is using mmap and another
using pwrite, we get incoherent results. As demonstrated by OpenBSD's
failure on the tdb unit tests.
Rather than disable mmap on OpenBSD, we test for this issue and force mmap
to be enabled. This means that we will fail on very large TDBs on 32-bit
systems, but it's better than the horrendous performance penalty on every
OpenBSD system.

OpenBSD doesn't idempotent-wrap sys/mman.h, so when we #define mmap to
an alternative, it fails to compile when sys/mman.h is included again.
Workaround is not to #define mmap to add arguments on Open BSD.

CCAN includes a little utility called "namespacize" which prepends ccan_ to
all public methods of a module, and fixes up any dependencies it finds. It's
a little primitive, but it works here.

By using a different include order, we end up with a different version of
FILE_OFFSET_BITS (and probably other things) in parts of the test. The
different variants get linked together, and the result is weird: the stat
returns 0 size.

On some platforms you can not debug coredumps after the default signal handler
gets done dumping core. This allows waf to have an option to disable our
default signal handler.

careful to include the replace headers before any standard headers (we are).

CommonCrypto/CommonDigest is available on Mac and there is function in
the libc for MD5 calculation. MD5Final is a C define of CC_MD5_Final.
Under some circumstance we have the symbol defined twice in samba
binaries on Snow Leopard at least.
By detecting CommonCrypto/CommonDigest we end up always using the system
version if available.

It's a bit confusing to mix low-level and high-level libraries. We had
multiple libraries in one directory, and there were have circular
dependencies with other libraries outside that directory (in this case,
samba-hostconfig).
