c9a67133d6 swapon/swapoff: -a returns 0 on ignored errors

a3f326cd66 swapon/swapoff: size reduction, cleanup, fixes, improvements 
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.

b9bbd4ddf6 fix interaction of -a and -p options in swapon 
Swap entries in /etc/fstab inherit the priority specified on the command line unless they have 'pri' in their mount options.

c3a27b0bfd avoid calling bb_strtou twice in MIN macro expansion 
Also, the maximum allowable value of swap priority is technically SWAP_FLAG_PRIO_MASK >> SWAP_FLAG_PRIO_SHIFT.

67b23e6043 getopt_ulflags -> getopt32. 
It is impossible to formulate sane ABI based on
size of ulong because it can be 32-bit or 64-bit.
Basically it means that you cannot portably use
more that 32 option chars in one call anyway...
