Make umount -f more compatible with util-linux 2.22.2.
Before:
* 'umount -f': calls umount syscall,
if it fails calls umount2 with 'MNT_FORCE'
* 'mount -f -l': calls umount syscall,
if it fails calls umount2 with 'MNT_LAZY'. 'MNT_FORCE' dropped
After:
* 'umount -f': calls umount2 syscall with 'MNT_FORCE'
* 'mount -f -l': calls umount2 syscall with 'MNT_LAZY' and 'MNT_FORCE'

Similar to the "big" util-linux version. For !DMESG_PRETTY, the option is accepted
(but ignored) as well, for compatibility reasons.

In commit b5c7220e7b
"fbset: respect rgba configuration lines in fb.modes"
I somehow managed to swap the offset/length markers around.
The man page for fb.modes says it should be offset/length
not length/offset as I was accidentally parsing it.
As my fb.modes file was also reversed I didn't notice
until I tried someone elses fb.modes file. Mea culpa.

Introduce a library routine to package the idiom:
p = xmalloc(b, n);
memcpy(p, b, n);
and use it where possible. The example in traceroute used xzalloc
but it didn't need to.

1) real swapon/swapoff handles also devices on the commandline with -a;
2) xstat(device) in swap_enable_disable aborts on error when cycling through
fstab so some devices are not handled;
3) duplicated code for ENABLE_FEATURE_SWAPON_DISCARD and
ENABLE_FEATURE_SWAPON_PRI was moved to functions.
4) silence some error messages with -a;
5) minor cleanups and code refactoring reduced the size as per bloat-check:
6) I also added support for /proc/swaps handling to swapoff:
"When the -a flag is given, swapping is disabled on all known swap devices
and files (as found in /proc/swaps or /etc/fstab)."
So now swapoff first cycles through /proc/swaps and then through fstab
to swapoff all devices.

fstrim applet is a port from util-linux.
"Trimming" your NAND/eMMC storage will restore the write performance
back to normal after having slow down issues on sequential write and
random write due to usage over time.

"losetup -d" was not complaining that LOOPDEV is missing.
"losetup -a" was listing only up to /dev/loop9.
"losetup -f" looped forever if llop0 was taken, and never tried
anything after /dev/loop9.
"-o" with other options (say, -r) had no effect.
