[PATCH 02/10] getopt: fix memory leaks and integer overflows [ASAN & valgrind]

[Sami Kerola]

The getopt(1) is short living command, and one could argue ensuring all
allocations are freed at end of execution is waste of time.  There is a
point in that, but making test-suite runs to be less noisy with ASAN is also
nice as it encourages reading the errors when/if they happen.

What will happen if some implementation will add new fields in `struct
option`? (Sure, unlikely, but).
IMO, `free((char *)option->name)` is *much* safer.

Hi Yuriy and Karel,

Okay, sounds fair adding a 'copy struct' wasn't the brightest idea ever.  
See below a const cast to read-write char pointer. This seems to make 
compiler happy.

[PATCH 03/10] lsipc, lslogins, rtcwake: replace asctime() with strftime()

[Sami Kerola]

POSIX.1-2008 marks asctime() and asctime_r() as obsolete, recommending the
use of strftime(3) instead.

stftime uses locale, asctime is not. And if you want *locale-specific*
time presentation, it is "%c" --- it can be very different from your "%a
%b...", e.g. compare with attached

   gcc -o asctime asctime.c
   LC_ALL=ja_JP.UTF-8 ./asctime

This is why I have asked for functions in lib/timeutils.c to make
short, full or iso formats explicitly defined on one place to avoid
creativity in utils code and such discussions.

We need:

 - human readable times:
    * full  (%c -- now asctime)
    * short ("%H:%M:%S, "%b%d/%H:%M", "%Y-%b%d")

 - ISO:
    * full
    * short
