Karel Zak 18b3e5495b swapon: split swapon-common.c
swapon    - requires libmount and libblkid
 swapoff   - requires libmount
 swaplabel - requires libblkid

This patch add lib/swapprober.c with blkid stuff for swap. It allows
to use and link libblkid only when necessary.

Sami Kerola 5db57cfc46 swapon: share get_swap_prober() with swaplabel to print uuid and label
The swapon(8) listing was almost complete, apart from label and uuid.
This change moves the code from swaplabel(8) to shared scope to be used
for printouts in other swap commands, such as swapon.

Adding this feature to lsblk(8) was a consideration, but lsblk is not
interested of swapfiles, so the swapon seems like a better option to add
this information.

It does not make sense to have writable large arrays of "struct

Fabian Groffen eb76ca98b0 build-sys: provide alternatives for err, errx, warn and warnx
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.

Davidlohr Bueso 8abcf29002 lib: [strutils] general purpose string handling functions
This patch replaces a few functions used throughout the source:
* Renames getnum (from schedutils) to strtol_or_err
* Moves strtosize (from lib/strtosize.c)
* Moves xstrncpy (from include/xstrncpy.h)
* Adds strnlen, strnchr and strndup if not available (remove it from libmount utils)

A few files were modified to compile accordingly along with trivial renaming
in schedutils source code.
