the addresses of the saved registers of frame described by FRAME_INFO.

* Makefile.in (init.c): Generate using the source, not munch. This
cleans up all kinds of hassles (which nm to use in munch, etc). The
new formatting conventions (mostly already followed) are that
the name of the _initialize_* routines must start in column zero,
and must not be inside #if.
* munch: Removed.
* Makefile.in: Remove references to munch.
* serial.c, remote.c, infptrace.c, maint.c, convex-tdep.c,
alpha-tdep.c, hp300ux-nat.c, hppab-nat.c, osfsolib.c, remote-es.c,

i960-tdep.c, hppa-tdep.c, h8500-tdep.c, dpx2-nat.c, delta68-nat.c,
z8k-tdep.c: Make sure the above conventions are followed. Make
sure they are all declared as returning void. Clean up
miscellaneous comments and such.
