The current optimization for small devices (1.4MiB) is broken. It
checks for partition table, but if nothing is detected then details
(ID_PART_ENTRY_*) about the current partition are not gathered.
The optimization should be enabled for small *whole* disks only.

This function currently sets the low or high values to 0 when the string doesn't
contain a value, like '123:' or ':123'. In order to make it more flexible, we allow it
to be passed an arbitrary value.

This function is currently only being used by partx(8), but it's handy and
generic enough that we can use it elsewhere as well.

Move chcpu man page to section 8 (admin commands) where it belongs.
Also update the contents of the man page.

Some people complained about the first letter of Yes/No as seen in the
online and configured column in the human readabe output being a capital
letter instead of the expected lower case letter.
So let's try to make everbody happy and convert them to lower case.

There's only one condition for which we declare success, but many for
failure. Initialize rc as failure and set to success on this single
condition. In all cases, jump to a label to exit instead of exiting
immediately. This will be used later on to ease cleanup of any heap
allocations.

The string returned from this function was never of much use other than
to stat the path when the user requested a major:minor pair beyond the
true/false exit. Save some processing and directly returning the dev_t
on success, and an impossible value on failure.

The lsblk depends on /sys/dev/block/ symlinks, which appeared in
kernel 2.6.27. Users with old, or non-sysfs configured, kernel
got ealier message
lsblk: md0: failed to initialize sysfs handler
lsblk: xvda: failed to initialize sysfs handler
[...]
that I found a little too difficult to understand. This patch will
change the message to
lsblk: failed to access sysfs directory: /sys/dev/block: No such file or directory
and informs in manual page what could be reason to that.

Without the check libmount builds on systems that has older than 2.7
glibc are silently unsuccessful. The missing %ms modifier will, at
least, result on such system missing output of findmnt and lsblk
commands. If either %ms or %as modifiers are present the libmount
build is disabled.
