DJGPP lacks sys/select.h and sys/un.h; add header checks to be more
portable.

Cygwin doesn't support lockf(), so move to fcntl() locking as more
portable. Also fix a bug which could cause get_lock() to loop forever
if the attempt to lock the file fails for some reason.

When compiling with dietlibc, sys/syscall.h isn't supported; as of
dietlibc 0.30, it exists but it references a non-existent asm/unistd.h
header file. So we have to test for its existence and avoid using it
in lib/uuid/gen_uuid.c if it is not supported.

Add a configure option which causes the uuidd helper daemon not to be
built or used by the uuid library.

If we fail to create the uuidd daemon after 5 or 6 tries, another
10,000 tries probably won't be successful.

The uuidd process will fork and let the parent process exit to create
the daemon. So use waitpid to reap the zombie, as well as using it to
time when it is safe to try to connect to the daemon.

/var/run can get completely removed at reboot, and uuidd doesn't have
permissions to recreate /var/run/uuidd. So instead use
/var/lib/libuuidd for the unix domain socket and pid files.

Also store the clock sequence information in a state file in
/var/lib/misc/uuid-clock so that if the time goes backwards the clock
sequence counter can get bumped. This allows us to completely
correctly generate time-based (version 1) UUID's according to the
algorithm specified RFC 4122.

Add in randomness based on Linux's thread id (gettid) to avoid race
conditions when two threads try to generate uuid's at the same time.
This shouldn't be an issue if /dev/urandom has proper locking and is
present, so this is just a failsafe.

This avoids a fd leak across an execve() which was causing problems
for the LVM tools.
