`enable' and `disable' identifiers, because some platforms define
in their system headers symbols with global scope that go by those
names.
* breakpoint.h (enum enable_state): Rename from `enum enable'.
Also rename all the enum members to have the "bp_" prefix.
(struct breakpoint): Rename the `enable' member to `enable_state'.
(enum bpdisp): Rename all members to have the "disp_" prefix.

is a valid code address.

* breakpoint.h (struct breakpoint): Doc fixes.
* breakpoint.h (enum bpdisp): Add del_at_next_stop.
* breakpoint.c (insert_breakpoints, watchpoint_check,
bpstat_stop_status): Avoid bad references to memory freed via
delete_breakpoint on watchpoints going out of scope.
Do not delete these watchpoints, disable them and change their
disposition to del_at_next_stop instead.
(breakpoint_auto_delete): Delete all breakpoints whose disposition
is del_at_next_stop.
(breakpoint_init_inferior): Use switch to avoid reference to
already deleted breakpoint.
Fixes dangling pointer problems with watchpoints.
(bpstat_what_main_action): New code BPSTAT_WHAT_THROUGH_SIGTRAMP.
* breakpoint.c (bpstat_what): Return BPSTAT_WHAT_THROUGH_SIGTRAMP
if we hit a bp_through_sigtramp breakpoint. Remove kludge which
ignored bs->stop for a bp_step_resume breakpoint.
* infrun.c (wait_for_inferior): Make a through_sigtramp_breakpoint
which performs one (the check_sigtramp2 one) of the functions
which had been handled by the step_resume_breakpoint. For each
use of the step_resume_breakpoint, make it still use the
step_resume_breakpoint, use the through_sigtramp_breakpoint, or
operate on both.
Deal with BPSTAT_WHAT_THROUGH_SIGTRAMP return from bpstat_what.
When setting the frame address of the step resume breakpoint, set
it to the address for frame *before* the call instruction is
executed, not after.
