If we are in FIPS mode certain ciphers like RC4 are not available, so
we should make sure we do not call them. We will add AES support in the
next patch.

This will explicitly zero data from memory. This is guaranteed to be not
optimized away.

Block the locker helper child by taking a lock on the 2nd byte of the
lock file. This will cause a ping timeout if the process is blocked
for long enough.

Allows blocking mode and start offset to be specified. Always locks a
1-byte range.
Make the lock structure static to avoid initialising the whole
structure each time.

The ping timeout is specified by passing an extra argument to the
mutex helper, representing the ping timeout in seconds.

In future this will allow extra I/O tests and a timeout in the parent
to (hopefully) release the lock if the child gets wedged. For
simplicity, use tmon only to detect when either parent or child goes
away. Plumbing a timeout for pings from child to parent will be done
later.

There will be more timeouts so clarify the intent of this one.

tmon_ping_test covers complex 2-way interaction between processes
using tmon_ping_send(), including via a socketpair(). tmon_test
covers the more general functionality of tmon_send() but uses a
simpler 1-way harness with wide coverage.

A convention when testing members of ctdb-util is to include the .c
file so that static functions can potentially be tested. This means
that such tests can't be linked against ctdb-util or duplicate symbols
will be encountered.
ctdb-tests-common depends on ctdb-client, which depends in turn on
ctdb-util, so this can't be used to pull in backtrace support.
Instead, make ctdb-tests-backtrace its own subsystem.

Also, rename ctdb_unit_tests to ctdb_util_tests. The sorting makes
it clear that only items from ctdb-util are tested here.

Commit f5a20377347aba18700d010d4201775fc83a0b1b arguably got this
back-to-front:

Unfortunately there is an inconsistency somewhere in the connection
tracking code used for tickle ACKs, making this less than obvious.
