Mostly by adding static and removing excess extern qualifiers.  Also
convert a few remaining non-ANSI function declarations to ANSI.

The DEFS line in MCONFIG had gotten so long that it exceeded 4k, and
this was starting to cause some tools heartburn.  It also made "make
V=1" almost useless, since trying to following the individual commands
run by make was lost in the noise of all of the defines.

So fix this by putting the configure-generated defines in lib/config.h
and the directory pathnames to lib/dirpaths.h.

In addition, clean up some vestigal defines in configure.in and in the
Makefiles to further shorten the cc command lines.

This is primarily to silence a gcc warning, but it's better to reflect
the error from system() up to the caller.  In this case we don't
actually use it for anything, but that's OK.

In case you're wondering about whether this change is safe from a
portability standpoint, fear not.  This has been beaten to death
in other forums.  Here are a few threads:

  http://thread.gmane.org/gmane.comp.version-control.git/74187
  http://thread.gmane.org/gmane.comp.lib.gnulib.bugs/12712
  http://thread.gmane.org/gmane.emacs.devel/98144
  http://thread.gmane.org/gmane.comp.lib.glibc.alpha/13092

There has been debate about whether it's a good idea from a
performance standpoint, too, but imho you'll have a hard time
finding an instance where this sort of change induces a
measurable performance penalty.  If you do, please let me know.

Fix a memory leak by freeing the argv[] array if ss_parse_line returns 0
for argc 0 (which will happen if the user his return and sends an empty
line to the application).

Potentially need to free argv before early return since it was allocated
memory. Need to be careful since it may be possible for ss_parse() to have
freed the memory allocated to it if it detects an unbalanced set of quotes
passed to it.
