bbd55fe16f Merge and commit patch.apic-zwane from CVS patches directory. 
the patch release notes by Zwane:

o Define symbols for constants like
o APIC arbitration
o Processor priority
o Various interrupt delivery fixes
o Focus processor checking
o ExtINT delivery

I need to release this now so that i don't fall too far behind CVS, when
it was part of the bochs-smp patch it could boot 2.4.18 4way. Apologies
for the whitespace changes.


Also remove patch.apic-ppr-zwane patch because it already included in
patch.apic-zwane.

I hope it will help to boot x86-64 or cmp systems required missed APIC
features !

98ef1412c3 - new graphics update API implemented (patch from Robin Kay) 
Description from the author:
  This API allows framebuffer device plugins to draw directly on to the
  GUI's tile buffer and hence eliminates the need to memcpy(3C) tiles to
  an intermediate buffer. Functions like update_hardware_cursor function
  are rendered unnecessary as framebuffer device plugins can now draw the
  full range of host colours. svga_cirrus will fallback to calling
  graphics_tile_update without a hardware cursor if the GUI doesn't support
  the new API. This patch includes implementations of graphics_tile_info,
  graphics_tile_get, and graphics_tile_update_in_place (the new API) for SDL
  and X11.
- new graphics update API implemented in wx and rfb
- common update functions for guis without support for the new API added (should
  be removed after implementing the new API in all display libraries)

8f0cf91fff This commit is the first commit in long series of changes the have several purposes: 
1. Review and commit patch

	[ 896733 ] Lazy flags, for more instructions, only 1 src op

   May be partially, but I hope to get all ideas from patch in

2. Get Bochs speedup after lazy flags optimization

3. Most important for me: improve correctness of emulation by handling several
   undocumented EFLAGS modifications. And finally pass

	UFLAGS - Undefined Flags Test v 3.0
	Copyright (C) Potemkin's Hackers Group (PHG) 1989,1995

   The test still fails on > 50% of its checks.

2. Fixed bug

[ 989478 ] I-Cache and undefined Instruktions

The L4 microkernel uses an undefined instruction to
trap for a special requests into the kernel (LOCK NOP).
The handler fixes this up and gives the user a special
code page with syscall stubs. If you're not using the
I-Cache optimization everthing works find on bochs. But
if you enable the I-Cache (--enable-icache), then the
undefined opcode exception is thrown only once for ever
virtual address it occurs. See the demodisk of the
L4KA::pistachio
(http://www.l4ka.org/projects/pistachio/download.php).
In this case the pingpong benchmark of this demo is of
interest. Everything runs fine until the program tries
to spawn a new task for its measurements. This new task
shares the code of the creating program. But the new
task stops executing at the undefined instruction
explained above and no exception is thrown.

f1a0f56d55 - support for serial port modes added. The mode defines what to do with the 
data written to the port and where to get the data read from it. Available
  modes are 'null' (no input/output), 'file' (output to a file specified as
  the 'dev' parameter), 'term' (serial terminal) and 'raw' (use the real serial
  port - under construction for win32).
- descriptions for serial and parallel options in bochsrc sample updated
