44b5d72b5a Added new functions to the debugger API:
{set,clear}_debugger_{break,watch}point(), allowing to set/clear break
and watchpoints for the calling team. When a break/watchpoint is hit,
the team enters the debugger. Handy in situations when the program in
question can't really be started in a debugger (or it would be
complicated to do so). The functions work only as long as no debugger is
installed for the team.

We clear the arch specific team and thread debug infos now, when a new
debugger is installed, thus clearing break- and watchpoints.

7f9c673981 * Introduced a new debugger message B_DEBUGGER_MESSAGE_HANDED_OVER, which
is sent to a debugger when the debugged team has been successfully handed
  over to another debugger.
* Fixed handling of B_DEBUG_MESSAGE_PREPARE_HANDOVER. We don't send a reply.

d2c78559a0 We now also support partial writes to the debugged team's memory.

291e414a9e * Somehow this B_DEBUGGER_MESSAGE_THREAD_STOPPED message bothered me.
Most of the debug events had their own message, but some were grouped
  into this `stopped' message with a `why' field to describe what kind
  of event it actually was. Hence the user had to check two levels until
  they could know what event occurred. So I got rid of this message and
  provided separate messages for the concerned events.
* Got rid of B_DEBUG_MESSAGE_GET_WHY_STOPPED and introduced
  B_DEBUG_MESSAGE_GET_CPU_STATE which is pretty much the same.
* Put B_DEBUG_MESSAGE_RUN_THREAD and B_DEBUG_MESSAGE_STEP_THREAD into
  a single B_DEBUG_MESSAGE_CONTINUE_THREAD message with a boolean
  `single_step' field.
* get_debug_why_stopped_string() -> get_debug_message_string().

1619a2e5b4 * The exceptions now have their own debugger message. Added
get_debug_exception_string() to get a user-readable string for an
  exception type.
* Added more signal support. Now the debugger can set per thread which
  signals it wishes to be notified of. It can also just ignore the next
  occurrence of a signal.

1c7fbde145 Added message def for preparing to hand over a debugged team to another
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.

a29ecae5f0 New debug function wait_for_debugger(). Useful when creating teams to be debugged via fork().

9b92e8c011 Added missing reply port for message B_DEBUG_MESSAGE_GET_WHY_STOPPED. Removed unnecessary alignment in debug_nub_set_cpu_state.

7586a0f3d6 Reading memory is more handy, if it allows for partial reads. So now the size is returned with the reply.

and setting the CPU state.

540103da09 * New function get_why_stopped_string() to get a human-readable
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.

433e1959ae Introduced a debug_origin structure consisting of thread and team ID of the concerned thread, and being first member of all messages sent to the debugger. This simplifies handling of messages in the debugger a good deal.

c3610c8098 * Architecture specifics live in arch/<arch>/debugger.h now.
* 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.

c53b50023a Trashed the old header and started a new one from the scratch.
Unless a good reason appears not to, we'll break binary compatibility here.
BDB could be considered one, but we need a replacement for it anyway. We
strive to port GDB and a couple of changes in the debugger API will make
that easier.

eafe61c06b * Some formatting cleanup.
* Removed ARM support.
* Removed PEF references.
* Added structure and constants for pre syscall tracing.
