- Folded duplicate code stdio_init_exit.c into a common function.

- Simplified the code in time_asctime_r.c which builds the time
  string. It gracefully handles buffer sizes which are too short
  by returning an empty string.

- Moved the tm->tm_wday initialization out of the hook function
  in time_strftime.c since it was to be called only once anyway.

- Lost a few compiler warnings in unistd_time_delay.c and
  time_gettimeofday.c.

- Folded duplicate code in time_mktime.c; also, errno is no longer
  modified unless the library is built with the CHECK_FOR_NULL_POINTERS
  option.
