Now it's necessary to explicitly create a lock for mnt_update_table().
It seems better to create the lock in mnt_update_table() by default to
skip this extra step.

The function blkid_evaluate_tag() is useful for tags only (e.g.
LABEL=foo). But we also need to address devices by tags OR paths in
many utils.
The function blkid_evaluate_spec() support this functionality without
extra care about the way how device is addressed. The tags as well as
paths are converted to the standardized device path.

This is not a bug ('ent' is always non-NULL is 'm' is non-NULL), but
let's keep static analyzes and humans who read the code happy.

Intel uses little-endians for UUID, the rest of the sane world uses 16

LVM (pvcreate) wipes the begin of the device. If there is a PT in the
wiped area then LVM signature is obsolete.
# pvcreate /dev/sdb
# fdisk /dev/sdb
old version:
# blkid -p -o udev /dev/sdb
ID_FS_TYPE=LVM2_member
new version:
# blkid -p -o udev /dev/sdb
ID_PART_TABLE_TYPE=dos

The problem with libuuid interface is that it is impossible to
inform the caller of uuid_generate_time() if the UUID was generated
in a safe manner (either via uuidd, or using the global clock state
counter).
This patch introduces new function,
int uuid_generate_time_safe(uuid_t out)
which can report whether the generated UUID is safe.

Having uuid_generate_time and uuid__generate_time at
the same time is confusing. These functions are exported,
but not part of the official API (used by uuidd only).

Solaris lacks err, errx, warn and warnx. This also means the err.h header
doesn't exist. Removed err.h include from all files, and included err.h from
c.h instead if it exists, otherwise alternatives are provided.
