6761f5a660 Move the handling of still running threads into scheduler_enqueue_in_run_queue().
This should be in line with all uses of scheduler_enqueue_in_run_queue() and
simplifies a few places where it is used.

34b3b26b3b Merged branch haiku/branches/developer/bonefish/optimization revision
23139 into trunk, with roughly the following changes (for details svn
log the branch):
* The int 99 syscall handler is now fully in assembly.
* Added a sysenter/sysexit handler and use it on Pentiums that support
  it (via commpage).
* Got rid of i386_handle_trap(). A bit of functionality was moved into
  the assembly handler which now uses a jump table to call C functions
  handling the respective interrupt.
* Some optimizations to get user debugger support code out of the
  interrupt handling path.
* Introduced a thread::flags fields which allows to skip handling of
  rare events (signals, user debug enabling/disabling) on the
  common interrupt handling path.
* Got rid of the explicit iframe stack. The iframes can still be
  retrieved by iterating through the stack frames.
* Made the commpage an architecture independent feature. It's used for
  the real time data stuff (instead of creating a separate area).
* The x86 CPU modules can now provide processor optimized versions for
  common functions (currently memcpy() only). They are used in the
  kernel and are provided to the userland via commpage entries.
* Introduced build system feature allowing easy use of C structure
  member offsets in assembly code.

Changes after merging:
* Fixed merge conflict in src/system/kernel/arch/x86/arch_debug.cpp
  (caused by refactoring and introduction of "call" debugger command).

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.

e68c6184ca user_debug_exception_occurred() now checks whether a non-default signal
action has been set for the signal. If so, it doesn't try to install a
debugger, but simply lets the caller deliver the signal.
Fixes bug #237 (VLC entering the debugger when checking for processor
extensions).

37a25a6ceb * Fail, if debug_thread() is invoked for the debug nub thread.
* To always be on the safe side, thread_hit_debug_event() now checks
  whether the thread is the debug nub thread.

6cd505cee7 Changed the boot procedure a bit.
Extracted scheduler_init() from start_scheduler() (which is now called scheduler_start()).
Moved scheduler related function prototypes from thread.h to the new scheduler.h.
Cleanup.

d3bdf71ea6 The debug nub port of a debugged team is owned by the debugger. Hence we
need to transfer the ownership, when handing over the team to another
debugger.

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.
