Various cleanups. Remove PDB pending simpler GDB stub and/or NetBSD debugger.
Force emacs mode to appropriate tabbing in various files.

Bug fix to the scheduler for writable page tables.
Don't flush the writable page tables inside __enter_scheduler()
until after we've committed to switching to another domain.
Here's the problem: if enough debugging messages are enabled (for
example, shadow mode and/or writable page tables messages), then we
can get into a situation where we *always* visit
__enter_scheduler() after every page fault and/or hypercall. If we
flush the writable page tables every time we take a page fault,
we'll never end up actually getting into the domain with write
permissions enabled to its page table.

Name: pic-lib.patch
Description: support PIC code generation
Libraries have 2 methods of being compiled; a .so must contain non-pic
objects, while the .a can contain standard objects.

Name: tools-misc-TARGETS.patch
Description: Split compile/link stages
distcc behaves much better when you compile and link in 2 separate steps.
Plus, this is a more standard way of doing things.

1. Deleted slab.c, added xmalloc.c. Do not rename header or remove
unnecessary includes (yet).
2. Add explicit align arg, although current implementation
over-aligns.
3. Add list_for_each_entry_safe().
4. Make xmalloc_array use _xmalloc_array, to avoid duplicate eval
of "num" arg.
5. Rearrange slab.h a little to show the exposed functions/macros
first.

Defined per-CPU SYSCALL entry point for hypercalls. We enter the DOM0
kernel and can receive hypercalls. Now probably need to fix the
user-access (uaccess.h) functions and macros.

x86_64 progress: now entering ring 3. Need a hypercall (SYSCALL)
entry point, and some kind of DOM0 image to test against.

Beginning a sprean clean of the USB code.
Lots of cleanups and fixes (thanks to Harry Butterworth for pointing out several
locking and allocation errors).

Add checking ISA DMA flag in cpu_loop. Also need to do bios_init manually
for now. With this change, floppy is functional.

More x86_64 progress: currently churning through construct_dom0.
Then will need a few extensions to entry.S and I can jump to ring 3.
To get hypercalls working I will need a SYSCALL entry point and also
to add uaccess.h/usercopy.S functionality.
