Remove bpstat_momentary_breakpoint. This was always kludgy
and is no longer used.
* breakpoint.h: Add enum bpstat_what.
breakpoint.h (struct bpstat), breakpoint.c (bpstat_stop_status):
stop and print fields of bpstat now per-breakpoint, not just
one for the whole chain.
breakpoint.{c,h} (bpstat_what): New function.
breakpoint.h: Remove bpstat_stop and bpstat_should_print.
infrun.c: Replace switch (stop_bpstat->breakpoint_at->type)
with call to bpstat_what.
README: Remove watchpoint/breakpoint bug from known bugs.
* breakpoint.h: Prototype bpstat_find_breakpoint.
breakpoint.h, tm-sun4os4.h, tm-sparc.h, sparc-tdep.c, tm-mips.h,
mips-tdep.h, tm-sun3.h, tm-68k.h, m68k-tdep.h: Add support for
stepping (and nexting) through longjmp(). Also, cleanup
breakpoint handling quite a bit by creating explicit breakpoint
types instead of using magic breakpoint numbers.
Makefile.in: Update version to 4.4.3
