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.

Removed the readline library (still available using if HAVE_READLINE is defined)
since it really doesn't play well with ncurses. The only real feature it added
was command completion, and it didn't really handle it completely correctly anyway.
(If readline printed a completion list, it completely screwed up the screen.)
We now use the wgetch ncurses interface to get input; this allows the PGDN and PGUP
keys to work correctly, and also helped fix up the resizing logic.
