all CPU specific implementations as much as possible.
AMD and Intel are now separated again, even though they are currently
equivalent besides the CPU vendor detection.

service depends on it, it doesn't make any sense to call it that early in the
game.
* The VFS now has a low memory handler for vnodes as well. If there is enough
memory left, it won't free any vnodes anymore.
* Potential crashing bug fix: some functions did not check if the FD passed
in belonged to the right type; they just assumed it had a valid vnode, but
it could have had a mount structure associated as well.

When memory gets low, the blocks on that list are also freed - but right now,
that only happens when a block is put back (not directly on demand, ie. via
a low memory handler).

* new arch_cpu_user_TLB_invalidate() that now does what arch_cpu_global_TLB_invalidate()

has not yet been tested, though - I'll do this after this commit):
* Removed the arch_memory_type stuff from vm_area; since there are only 8 memory
ranges on x86, it's simply overkill. The MTRR code now remembers the area ID
and finds the MTRR that way (it could also iterate over the existing MTRRs).
* Introduced some post_modules() init functions.
* If the other x86 CPUs out there don't differ a lot, MTRR functionality might
be put back into the kernel.
* x86_write_msr() was broken, it wrote the 64 bit number with the 32 bit words
switched - it took me some time (and lots of #GPs) to figure that one out.
* Removed the macro read_ebp() and introduced a function x86_read_ebp()
(it's not really a time critical call).
* Followed the Intel docs on how to change MTRRs (symmetrically on all CPUs
with caches turned off).
* Asking for memory types will automatically change the requested length to
a power of two - note that BeOS seems to behave in the same, although that's
not really very clean.
* fixed MTRRs are ignored for now - we should make sure at least, though,
that they are identical on all CPUs (or turn them off, even though I'd
prefer the BIOS stuff to be uncacheable, which we don't enforce yet, though).

It also fixed a bug in the old code - the handshake semaphores were created
acquirable, causing the BDirectWindow::DirectDaemonFunc() to call DirectConnected()
with an uninitialized buffer and way too early - this probably didn't show up
before since it called it before the BDirectWindow constructor ran through,
so that DirectConnected() would still point to the BDirectWindow version, and
not to the implemented one of its subclass...

Rearranged the IconCache node_ref hash computation to be padding-resistant

one of the TODOs already says, the architecture specific parts should be
factored out into separate source files.

but it compiles at least. :-)
* Pulled the architecture specific part out of <posix/setjmp.h> into
<posix/arch/<arch>/arch_setjmp.h>.
* Moved setjmp_save_sigs.c from the x86 specific implementation into a
"generic" sibling directory, since it is reusable (and actually used
by the PPC implementation).
* Added generic/longjmp_return.c containing a function __longjmp_return,
which is invoked at the end of siglongjmp(), resetting the signal mask
and validating the return value. It is used by the PPC implementation,
and should also be used by the x86 implementation, but I'll leave that
to someone who's motivated enough to also test it. :-)

using the clipping info from a BDirectWindow... I made it so that the window
used stays on top always, until I can think of something better. The other
problem is that you should not move the window, since Painter doesn't update
it's pointer into the frame buffer.
* Now the test environment is running at pretty much the same speed as it would
under Haiku, completely by-passing the BeOS app_server. It shows that Painter
needs to be optimized for writing to graphics memory, and also that we need to
figure out a way to distribute update sessions more equally. What happens is
this: The first invalidation of a window triggers an update on the client
side... the client cannot keep up with drawing, since it is pretty much
blocked all the time because the desktop thread moves a window and because
the clipping constantly changes. In the meantime, new update request are
added to the pending session because the client has still not finished with
the current session. Only when things settle a bit, the next update session
can be startet. On the bright side of things, the earlier problems with
scrolling seem to be fixed for good.
* some documentation updates on Painter

functions from glibc 2.3.2. Adding those one by one is extremely
boring and time-consuming work. We should probably just remove the
math stuff again, add a verbatim copy of the glibc directories, and
shuffle things around afterwards.
* Note that for x86 holds sizeof(long double) == 96. I removed the
generic 128 bit long double functions that were in use before and
added respective 96 bit versions to arch/x86 (or left them out, if
they weren't used). For PPC the System V ABI spec supplement specifies
sizeof(long double) == 128, but I had trouble configuring gcc to
actually use that setting (looks like there simply is no support for
TI mode for PPC 32). So we have to live with sizeof(long double) ==
sizeof(double) == 64 for the time being.
