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.

2c97a8d164 Use -I instead of -isystem for system header directories when building
with gcc 4. Fixed resulting build errors (gcc is more lenient for
headers in -isystem directories).

1cbf8f4b3c initial support for a commpage, which is a chunk of memory in high kernel space with user readonly permissions.
The first use is to let the kernel decide what the preferred syscall mechanism is at boot time and copy the
appropriate user space code there. Can be used for routines the kernel can decide best how to use (memcpy, some
timing routines, etc).

716a16ce61 * Find out a few interesting information about the system (like CPU,
bus, and time base frequency) in the PPC boot loader, and propagate
  them to the kernel via kernel_args.
* Now we use the correct time base frequency for timer calculations.
* Implemented PPC specific system info stuff. Added a few PPC CPU
  types to <OS.h>.

758b1d0e05 Fixes that make Haiku build with gcc 4. Mainly out of the following
categories:
* Missing includes (like <stdlib.h> and <string.h>).
* Linking against $(TARGET_LIBSTDC++) instead of libstdc++.r4.so.
* Local variables shadowing parameters.
* Default parameters in function definitions (as opposed to function
  declarations).
* All C++ stuff (nothrow, map, set, vector, min, max,...) must be imported
  explicitly from the std:: namespace now.
* "new (sometype)[...]" must read "new sometype[...]", even if sometype is
  something like "const char *".
* __FUNCTION__ is no longer a string literal (but a string expression), i.e.
  'printf(__FUNCTION__ ": ...\n")' is invalid code.
* A type cast results in a non-lvalue. E.g. "(char *)buffer += bytes"
  is an invalid expression.
* "friend class SomeClass" only works when SomeClass is known before.
  Otherwise the an inner class with that name is considered as friend.
  gcc 4 is much pickier about scopes.
* gcc 4 is generally stricter with respect to type conversions in C.

1c016e0e3f Cleaned up OS.h a bit more.
Return type of thread_func is now status_t instead of the previous int32.
Added some more cpuid_info fields - many fields aren't just reserved anymore.
"sysinfo" now supports the extended features of Intel CPUs, and also knows
the "HTT" bit of the standard features indicating the hyper-threading capability.

794df3bf25 This removes the inline assembly code for find_thread
from OS.h, sorry for triggering a complete rebuild.
To avoid doing a syscall for find_thread(0), the assembly
version is now in libroot. For BeOS R5 compatibility, 
_kfind_thread_ is retained. This will fix some compile 
problems, and provides a cleaner OS.h for future Haiku
versions.

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.

183dee22cb Unlike R5, receive_data() could return an error code under Haiku - this
can now only happen if the thread is killed.
_user_receive_data() will now longer pass B_CAN_INTERRUPT to receive_data(),
but B_KILL_CAN_INTERRUPT - this should fix the problem Stefano experienced
with this function, even if I couldn't reproduce it.

34e92cad76 Added and implemented new system calls switch_sem() and switch_sem_etc(); even if
they are public now, they might become private later on.
It's almost the same as acquire_sem() but allows you to release another semaphore
atomically. This makes condvar implementations and the like very simple to do.
Added B_CHECK_PERMISSION flags to the user calls, although it's not honored yet.

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.

9a28130b32 Added (currently only) flag B_WAIT_TILL_LOADED for _kern_load_image()
(maybe this should better go into a private header?). If given the function
waits till the loader is done with loading and relocating the executable.
Otherwise it returns before the loader starts.

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.

    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.

bc93cc3fa7 Happy source compatibility breaking:
- Removed the OBOS_CPU_TYPE stuff - our types are now always defined.
- Made the cpu types consistent, renamed X86 to x86.

- Renamed cpuid_info.eax_0.vendorid to vendor_id.
- changed B_CPU_x86_VENDOR_MASK to 0xff to make some space for future changes.
- added some more CPU types (if anyone knows more Transmeta IDs; I
  couldn't find more of them).

9de969006b Added two experimental release_sem_etc() flags (both should stay, but they
may be renamed):
- B_RELEASE_ALL: the semaphore count is set to 0, all waiting threads are released
  (the "count" argument of release_etc_sem() is ignored then)
- B_RELEASE_IF_WAITING_ONLY: the semaphore count is only decreased if there
  are any waiting threads; ie. the semaphore is signaled
Together, they will make the pthread_cond_*() functions easy to implement, and
they come in handy at other places, too.
