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.

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.
