- Use ANSI-C function definitions for all of the functions
mentioned above plus strtouq and strtoq.
- Update the prototypes in the manual pages.

Hopefully, now it is more clear that the memory referenced by the
ptr argument of realloc(ptr,size) is freed and only the return value
of realloc() points to a valid memory area upon successful completion.

Also, make an internal _getprogname() that is used only inside
libc. For libc, getprogname(3) is a weak symbol in case a
function of the same name is defined in userland.

sbrk() and brk() are not thread safe. Replace use of sbrk() with
a call to malloc to avoid race when one thread calls atexit
while another thread calls malloc.

According to C99:

affect the value of the integer expression errno on an
error. If the value of the result cannot be represented,
the behavior is undefined."

as well as NetBSD's one.

The definition of character class digit requires that only ten characters
-the ones defining digits- can be specified; alternate digits (for
example, Hindi or Kanji) cannot be specified here. However, the encoding
may vary if an implementation supports more than one encoding.
The definition of character class xdigit requires that the characters
included in character class digit are included here also and allows for
different symbols for the hexadecimal digits 10 through 15.
