a608485f26 * Added new team flag B_TEAM_DEBUG_PREVENT_EXIT that prevents teams from exiting
via exit() (the calling thread will drop into the debugger instead).
* The DebugServer now uses this flag by default.
* Added TODO comment: the default debugger should already be able to set a flag
  like this in order to close a race condition between dropping a thread into
  the debugger and setting the flag.
* Cleaned up the debug_server sources a bit.

0b11ecb18c * Always include the public arch_debugger.h headers. The structures defined
there are prefixed with the respective architecture name. Useful for remote
  debugging a different architecture.
* <x86/arch_debugger.h>: Introduced a structure for the FPU state, so that it
  isn't left to the debugger.
* Removed the _kern_get_thread_cpu_state() syscall. Was originally intended for
  bdb compatiblity, but isn't really needed.
* Kernel x86 arch_get_debug_cpu_state(): The use of fnsave was broken, since
  it reinits the FPU after saving the state. This resulted in weird results
  when debugging functions using the FPU. We now use fxsave, if available.
  Otherwise fnsave + frstor should be used -- not fully implemented yet.
  Same for arch_set_debug_cpu_state().

b0f12d64f4 Added transparent software breakpoint support for user debuggers:
* The bulk of the work -- i.e. juggling the software and hardware breakpoints,
  watchpoints, and memory reads/writes -- is done in the new class
  BreakpointManager.
* For the architectures a few capability macros have to be defined, one
  pointing to the software breakpoint instruction opcode. Done for x86.
* Some more simplifications in the user debugger code, made possible by the
  recently introduced debugger_changed_condition attribute.

e1975d3353 * When a team debugger is installed automatically, the thread causing that is
stored now.
* Extended the debugger message for B_DEBUGGER_MESSAGE_HANDED_OVER by the
  causing thread.
* Also send B_DEBUGGER_MESSAGE_HANDED_OVER to the debugger to which the team
  was handed over. The message will be the very first one the debugger gets
  from the team in question.
* Some harmless refactoring (added thread_hit_serious_debug_event()).

f965a969b1 Extended the profiling API. When using the variable stack trace depth
buffer format, the buffer can now also contain other events than just
stack traces. ATM these are only references to the image events
(created/deleted). Therefore we no longer have to flush the profiling
buffer after such an event, since the debugger can exactly match the
samples. Since we couldn't flush when the profiling timer hit while the
thread was in the kernel, that wasn't working that well anyway.
"profile -f" fails to translate stack trace addresses only very rarely,
now.

0135e2e324 * Increased the maximum profiling caller stack depth significantly.
* Extended the profiling API by an option to record a variable number of
  samples per tick. The stack depth is used as a maximum.
* Added new option "-f" to the "profile" tool. When specified it
  increments the hit counts of all symbols in the full available caller
  stack. I.e. the resulting hit counts will approximate the total time
  spent in each function or any function directly or indirectly called
  by it. Thus "_start" and "main" will usually get 100% and leaf
  functions only what time has actually been spent in them.

ecfad924e0 Solution for the potential deadlock when needing to flush the profiling
buffer during a timer event that interrupted a kernel function: We do
now flush the buffer as soon as it is 70% full, *if* we didn't interrupt
a kernel function. When the buffer runs full and we still haven't hit a
user function, we drop the tick. The number of dropped ticks is recorded
and sent to the debugger with the next update message.
Reverted the previous partial solution (the temporary disabling of
profiling while in debugger support code).

eba9a4c3ee * Introduced a per-team counter that is incremented whenever an image
is created or deleted (or exec*() has been invoked). The counter is
  sent with several debugger messages.
* Track the image event counter that is used when samples are added to
  the profiling buffer. If the current team counter differs, we flush
  the buffer first (sending an update message to the debugger), so that
  the debugger has a chance to match the addresses to the correct images.
* Disable profiling for a thread while it runs in the debugger support
  code. This fixes potential deadlocks which could occur when a
  profiling timer event occurred that would require the buffer to be
  flushed while the thread was just sending something to the debugger or
  waiting for a command. As it turns out, this is not sufficient either,
  since we should never try to flush the buffer when the timer event
  occurred in the kernel, since the thread might hold a lock that the
  debugger thread could try to acquire. Will implement a more general
  solution later.

424f833bc9 * Changed the profiling API: Instead of sending all functions that shall
be tracked to the kernel, which then counts the hits, an area is
  passed to kernel in which the hits are recorded. When the area is
  full, the debugger is notified. For some reason that part doesn't work
  yet -- the whole system freezes when waiting for a reply.
* Reorganized the profile tool code a bit. For one with respect to the
  changed API, but also to prepare tracking of image creation/deletion.

cbcebd3330 * Extended the debugger API by sampling-based profiling support. This is
still pretty much work in progress.
* Introduced init_thread_debug_info() which is used instead of
  clear_thread_debug_info() when the thread is created. The latter
  requires former initialization.
* user_debug_thread_deleted() is now already invoked in thread_exit(),
  not in the undertaker.

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.

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().

get_debug_exception_string() to get a user-readable string for an

* 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.

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.
