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).

636bfc08ae * Renamed fs/vfs_select.cpp to wait_for_objects.cpp and got rid of
vfs_select.h, respectively moved most of it into the new kernel
  private header wait_for_objects.h.
* Added new experimental API functions wait_for_objects[_etc](). They
  work pretty much like poll(), but also for semaphores, ports, and
  threads.
* Removed the "ref" parameter from notify_select_events() and the
  select_sync_pool functions as well as from fd_ops::fd_[de]select(). It
  is no longer needed. The FS interface select() hook still has it,
  though -- the VFS will always pass 0.
* de]select_fd() take a select_info* instead of a select_sync* + ref
  pair, now. Added respective functions for semaphores, ports, and
  threads.

4bfe6b4b7f Don't reschedule at the end of every syscall. Speeds up syscalls by about 15%.

ea4ff0f689 is_computer_on() lives again as a true syscall.
Replaced the _kern_null syscall with _kern_is_computer_on.
is_computer_on_fire is a bit harder, since it returns a float from kernelland, which
at the moment isn't supported in haiku.

89ae57ba77 Removed sysctl(), there is no need for this BSD-ish call.

c88974d026 The app_server now updates the kernel's blue screen frame buffer on mode changes
(only the accelerant HW interface does this for now).
