* Implemented _user_wait_for_debugger().
* Reworked a few bits to ensure that after a remove_team_debugger() or
after requesting a debugger handover the debugger doesn't get any more
messages.
* When the debugger is removed or dies, the debugged threads should now
cleanup their debug info and continue, instead of waiting at their
debug port forever.
All the new features are not tested. Will happen, when gdb will be
debugged.

debugger. After successful reply to the message the debugger won't receive
any more messages from the debugged team. The mechanism is completely
transparent to the target debugger. It simply installs itself as debugger
for the team.

zooey agreed when discussing this (and we hope this don't break anything)

threadID parameter to spawn_kernel_thread_etc(). It's now possible to
set the ID of a new thread. Used in team.c to make team ID and the ID of
the main thread equal.
Fascinatingly the two added functions prompt my compiler to issue
`missing prototype' warnings, although those are obviously there. It would
be nice if someone could solve that riddle.

we only have 3 debug registers available for break-/watchpoints.
* Added definitions for debug status register DR6. Reordered DR7 defs to
ascending order. Added definitions for the EFLAGS flags we need.
* Added arch_thread_debug_info structure and related definitions.

needed to get the topmost user iframe. Added i386_get_user_iframe() for
exactly that purpose.
* Added reinitialization of user debugging for the new thread when
switching the context.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11523 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Made the parameter for restoring the FPU state const.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11522 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added event callbacks for break- and watchpoints and single stepping.
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11520 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Removed orig_e{a,d}x. We will always report those in e{a,d}x.

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

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.

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
* 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.

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.
