blkid: split SONAME and LIBBLKID_VERSION
It seems better to split SONAME and the public library version. The
library version will be the same as util-linux-ng PACKAGE_VERSION.
PACKAGE_VERSION: <maj>.<min>[-<suffix>] e.g. 2.15-rc2
Symbols versioning: BLKID_<maj>.<min> e.g. BLKID_2.15
blkid_get_library_version(): <maj>.<min>.0 e.g. 2.15.0
SONAME: libblkid.so.1

blkid: remove whole-disk entries from cache when partitions are found
We can get into a situation in blkid where whole disks remain
in the cache, even though partitions are found. For labels
such as sun disklabels which may have the first partition
beginning at sector 0, this is even somewhat likely.
1) create a sun disklabel w/partitions
2) mkfs the first partition (at sector 0)
3) remove the partition table
4) run blkid - this finds the fs on the whole disk, places in cache
5) recreate the partition table
6) run blkid - this finds the partition, places in cache
And now we have both /dev/sda and /dev/sda1 in cache.
There are heuristics in probe_all to avoid putting the whole disk
in cache if it has partitions, but there is nothing to remove the
whole-disk entry in the above case. I think the below patch
suffices, although I haven't quite convinced myself that setting
the lens[which]=0; is the right logic for that bit of state...

login: use open(2) rather then access(2) for $HOME/.hushlogin
As an NFS client with home directories on mounted NFS share - If the
NFS server exports the share with default root squashed, login cannot
access the filesystem to check for the existence of .hushlogin file.
It seems better to use open(2) rather than access(2).

hwclock: add --systz option to set system clock from itself
Since the system clock time is already set from the hardware clock by the
kernel (when compiled with CONFIG_RTC_HCTOSYS), there's no particular need to
read the hardware clock again.
This option sets the system clock using itself as a reference if the
hardware clock was in local time. The resulting system clock time
is in UTC, with the kernel timezone set to the difference.
