2ed21b8525 Some work in progress of the MTRR support. Shouldn't do any harm yet :-)

67a7102658 Fixed a pretty fatal bug in the page fault handling: interrupts were enabled
even if "kernel_startup" was "true". Page faults are now no longer allowed
during kernel startup (and could be easily avoided). The only situation where
we accept page faults with interrupts turned off now is during a kernel debugger
session.
Added a command debug_debugger_running() to test for that situation.
kernel_debugger() no longer sets kernel_startup while it's running; there should
be no situation when this could be helpful.
Interrupts are no longer enabled when a page fault happens in the kernel
debugger.
This potentially fixes all sorts of problems, and not only in the kernel debugger,
it could also have affected SMP (will test later).

ed65cbe349 The kernel debugger no longer uses dprintf() but kprintf() when printing
(dprintf() locks using acquire_spinlock() which can itself drop into the
kernel debugger, causing an endless loop (until the stack was full).
Removed debug_putchar().
The gdb interface is now calling arch_debug_serial_*() directly.

f33c8020e2 Removed debug/console.c, we no longer need it. frame_buffer_console_init() is now
called by debug_init_post_vm().
Since the availability of a blue screen specific getchar() is static anyway, there
is no need for the sBlueScreenGetChar variable (only the message "only serial input
available" gets lost, but since that is platform specific anyway...).
Hello blue screen! We now have an on-screen KDL, to be enabled by the kernel
setting "bluescreen", just like on BeOS.
The blue screen does not yet support any cursor actions or backspace, though (need
to grab some stuff from our console driver).

9a63135f7c Cleanup of the debug stuff, prepared for blue screen debugging.
kernel_debugger() didn't do enough before; panic() did all the work - but
since the former is a public function as well, I moved all the functionality
to it. Also fixed a possible buffer overrun in panic().
Renamed dbg_* to debug_*.
"serial_debug_port" setting did not ignore negative values.

b0d8e689ac Renamed some more init2 routines to init_post_vm() to make it clearer when
and why they are called.
Introduced a cpu_init_post_vm() that will now call arch_init_post_vm() instead
of letting main() doing it.
Fixed some return types (mostly from int to status_t).

3d78db8f17 Removed B_KDEBUG_* definitions; they are already part of KernelExport.h.
dbg_register_file[][] reserves now space for SMP_MAX_CPUS CPUs.
Removed old dbg_{set|get}_serial_debug() functions.
