functions for setting break-/watchpoints (implemented).
Break-/watchpoints don't work yet, though. Missing is still the setting
of the debug control register DR7 somewhere in the interrupt code and
the handling of debug exceptions.

debug infos.
* Added function for setting the CPU state.
* Added functions for setting break-/watchpoints.

* In team_delete_team() we no longer explicitly destroy the team debug
info. It is not necessary, since the terminating debug nub thread will
do that anyway. Moreover we access the debugger port in a safer manner
now.

by the team lock, but by a lock in the structure. This is necessary
since we can't acquire the team lock while thread switching, for then the
thread lock is already held.
* Added support for single stepping and break-/watchpoints.

to trim the templatized interface improves the situation, but we're still
quite heavy (400 KB).

(Daniel Furrer).
* The strace interface for the generated file changed.

waiting for teams to crash to show our favorite alert.
Due to the missing app_server we don't show a alert yet. We just print
something to /dev/dprintf and kill the team. Unlike R5's debug server
ours will probably not provide any debugging functionality itself, but
rather employ gdb directly.

* Now a debugged thread and the debug nub thread are not longer blocking
on ports when they receive a SIGKILL[THR] (we couldn't kill a debugged
team before).
* Small fixes. More correct cleanup when the debug nub thread terminates.

translation for the debug_why_stopped codes.
* Added nub_port member to debug_origin structure, so that now all
synchronous messages to the debugger also include the debug nub port.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11489 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added is_kill_signal_pending(). Can anyone tell me why the compiler
complains about a missing previous prototype for it? <ksignal.h> is
included, and when only preprocessing the file, the prototype is clearly
there. I'm clueless.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11488 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Removed SIGKILLTHR from BLOCKABLE_SIGS.
* Made header C++ safe.
* Added function is_kill_signal_pending(), returning true, if a
SIGKILL[THR] is pending for the current thread.

interruptable by SIGKILL[THR], even if B_CAN_INTERRUPT is not set. Not
sure, if this is the best solution, but it works.

- If the thread's B_THREAD_DEBUG_STOP flag is set, it is now always
stopped before handling the signals. Unless a SIGKILL[THR] signal is
pending.
- Also notify the debugger, when a signal is ignored.
* The signal's sigaction structure is additionally passed to the debugger
now.

* Now we deal correctly with thread debug flags (child threads inherit
the parent ones, save for syscall tracing in which case it needs to
be specified explicitly).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11477 a95241bf-73f2-0310-859d-f6bbb57e9c96
In the first case this is probably too early, since the image is not
really loaded at that time by the loader. We should probably introduce
a syscall the loader can invoke for that purpose.

convenience.
* Added/implemented callbacks for almost all missing debug events (team,
thread, image creation/deletion, exceptions/faults, signals).
* The debugger can now specify how to deal with the event that stopped an
event (ignore or handle signals, exceptions/faults).
* Implemented B_DEBUGGED_THREAD_GET_WHY_STOPPED debugger message.
* The cpu_state is now passed to the debugger with
B_DEBUGGER_MESSAGE_THREAD_STOPPED notifications.
* Completed _user_debugger() implementation.

* team debug flags:
- Added flags for team creation, thread events (creation,
deletion), and image events (creation, deletion).
- Got rid of B_TEAM_DEBUG_SYSCALL_FAST_TRACE. We always send the syscall
arguments. The overhead should be neglectable.
- Added B_TEAM_DEBUG_STOP_NEW_THREADS.
* Added debugger notification messages for signals, team, thread and
image events.
* Added debug request B_DEBUG_MESSAGE_GET_WHY_STOPPED.
* When continuing a thread, the debugger can now specify how to deal with
the occurred event (ignore or handle).
* More data in the signal received notification message.

I also fixed my power button, so I don't need to test acpi_button by shorting motherboard contacts with a screwdriver...
