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.

Users have reported problems on newly installed systems when the
Macintosh's system clock battery is dead and the hardware clock is
returning a date of 1904. Turns out there were some bugs in handling
dates before the Unix epoch.
Addresses Red Hat Bug: #182188
probe.c (blkid_verify): Fix the bid_time sanity checking logic,
so that if last verification time is more recent than the
current time, or the comparison between the last
verification time and the current time causes an overflow,
a device verification will take place.
devname.c (blkid_get_dev): Set the initial bid_time to be
INT_MIN, to guarantee that blkid_verify will always be run
even when the system clock is insane.
dev.c (blkid_debug_dump_dev), read.c (debug_dump_dev),
save.c (save_dev): Fix the printf format for dev->bid_time
to match the fact that it is an signed type.

1) Only one tag with a particular name can be attached to a device
at a time. This significantly simplifies the library, and was needed
to allow the cache file to be re-read and changes integrated into the
in-core version of the data structure in a simpler fashion than earlier
versions of the library.
2) To accomodate this, the ext2/ext3 filesystems are now always tagged
as "ext2" type filesystems. Ext3 filesystems are tagged with a
SEC_TYPE tag with the value ext3.
3) The new blkid_read_cache() function checks the mod time of the
cache file, and if the file has been changed since the last time the
cache file was read into memory, it is re-read. This function is now
called before probing all of the devices in the system or searching
all devices in the cache for a specific tag value.
4) After probing all devices, blkid_flush_cache() is called to write
out the cache file. This assures that all of the hard work involved
in doing a blkid_probe_all() is saved to disk.
read.c (parse_tag): Do not return that blkid_tag when parsing
the blkid.tag file.
resolve.c (blkid_get_token, blkid_get_tagname_devname): Fold in
code from removed functions
tag.c (blkid_create_tag): Don't return the newly tag strcture
any more, as it's not needed.
(blkid_find_tag_cache, blkid_get_tag_cache,
blkid_token_to_tag, blkid_find_tv_tags): Remove these
functions, as they are either only used once or have
interfaces that should be deprecated.
(blkid_find_tag_dev, blkid_find_head_cache): Replace use
of blkid_tag with one or two const char * type/value
arguments.
(blkid_find_dev_with_tag): Fold in code from removed functions
probe.h, probe.c: Use a more sophisticated set of byte-swapping
routines which are more compact and efficient. Drop
calculation of bid_free, since it's unnecessary. Avoid
save.c (blkid_save_cache): Set the permissions on the blkid
cache file to 644.
