The getopt() function will never let optarg be NULL (at least without
using the GNU double-colon extension, which we don't use because it's
not portable), so don't bother checking for that case. It's harmless,
but it triggers a Coverity warning elsewhere, since it thinks optarg
could in fact be NULL.

The DEFS line in MCONFIG had gotten so long that it exceeded 4k, and
this was starting to cause some tools heartburn. It also made "make
V=1" almost useless, since trying to following the individual commands
run by make was lost in the noise of all of the defines.
So fix this by putting the configure-generated defines in lib/config.h
and the directory pathnames to lib/dirpaths.h.
In addition, clean up some vestigal defines in configure.in and in the
Makefiles to further shorten the cc command lines.

Also accessed via -o list, this new output format is much more

When printing the value of tags in a formatted format, print control
characters and characters with the high eight bit set using the ^ and
M- notation, respectively. This prevents a filesystem with a garbage
label from potentially screwing up the user's screen (for example,
putting it into graphical mode).

for a single device.
Add a new function to the blkid library, blkid_probe_all_new().
Optimize blkid_find_dev_with_tag() so that extraneous device validation are
skipped. (Makes a difference for system with a large number of disks).
consistently when the blkid cache file is explicitly set
to /dev/null. (Addresses Debian Bug #292425)
Also expose blkid_verify() as a public function to the blkid library.
