Forgetting to re-set log_file->size after truncating to zero
discards log-data for the next 1 second following an oversize-induced purge,
when we shouldn't necessarily throw that data away.

Closes 627 and 7034.
Commonly seen case is (un)loading of an alias
which matches ata_generic and a more specific ata module.
For example:
modprobe [-r] pci:v00008086d00007010sv00000000sd00000000bc01sc01i80
(ata_generic and pata_acpi)
modprobe [-r] pci:v00001106d00000571sv00001509sd00009022bc01sc01i8a
(ata_generic and pata_via)

For certain cross build scenarios the LD variable is overridden
to use the gcc executive to ensure all the target tuning parameters
are used. In these cases, the executive errors out as shown below
but since this step is only linking to a .o file the standard libs
are not needed.
$ make LD=gcc applets/built-in.o
LD applets/built-in.o
/usr/bin/ld: cannot find -lgcc_s
/usr/bin/ld: cannot find -lgcc_s
collect2: ld returned 1 exit status

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.
