* To always be on the safe side, thread_hit_debug_event() now checks
whether the thread is the debug nub thread.

having the thread lock held and interrupts disabled.
Cleaned up the signal handling code, and fixed some minor bugs with blockable
vs. non-blockable signals.
thread_debug_info was using uint64 for signals sets instead of sigset_t.

* Added initialization function. Currently only need to init the
single step hack for qemu.
* Fixed a deadlock when the nub thread destroyed the debug info. It was
waiting for itself.
* Moved the filling in the origin info of the debug messages into
thread_hit_debug_event_internal(). No need for code duplication.
* Writing to user memory can now be partial. We also change the area
protection, if it wasn't writable. Necessary for setting software
breakpoints.

* user_debug_break_or_watchpoint_hit() into separate functions for
break- and watchpoints. The one for breakpoints gets another parameter
which indicates whether the breakpoint was a soft- or hardware
breakpoint. This info is also sent to the debugger.

not to be notified.
* Added debugger commands for setting/getting of thread signal ignore
masks and signal handlers.
* Renamed user_debug_fault_occurred() to a more correct
user_debug_exception_occurred(). It no longer sends a `stopped' message,
but the new one dedicated to exceptions. Additionally the number of the
signal is supplied that will be sent, when the thread continues (without
indicating to ignore the event).
git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11703 a95241bf-73f2-0310-859d-f6bbb57e9c96
* 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.

* Added event callbacks for break- and watchpoints and single stepping.

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.

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.
