Removed support from libxc and mini-os.
This also took me under xen/include/public via various symlinks.
Dropped tools/debugger/xenitp entirely, it was described upon commit
as:
"Xenitp is a low-level debugger for ia64" and doesn't appear to be
linked into the build anywhere.

The latter is GPL which makes the whole of mini-os GPL rather than BSD
as intended. In tree users are all GPL or GPL-compatible but we should
fix this so that mini-os is BSD. Do so by using the same BSD
sys/queue.h as we use in libxl.
Tested with the builtin mini-os test app and qemu stubdomain, both of which
appear to still function as expected.
Move tools/libxl/external and the associated sed script to
tools/include/xen-external to allow more sensible access from mini-os.
Also add s/NULL/0/ in the sed script due to NULL not always being
defined in stubdom code when mini-os/wait.h is included.
As well as the obvious ABI changes there are a few API updates
associated with the change:
- struct rw_semaphore.wait_list is unused
- remove_waiter needs to take the wait_queue_head
The latter requires a qemu update, so there is also a QEMU_TAG
update in this changeset.
I sprinkled some extra-emacs local variables around the files I edited
which didn't have them.
I think this should be backported to the stable branches since
external users of mini-os may have been mislead into thinking they
could safely link mini-os against GPL-incompatible code.

This is a necessary step to make minios build on NetBSD.

Currently the minios headers do this:
#define current get_current()
Obviously when porting general code to this environment, this can
cause problems !
The attached patch arranges for this only to be done if
#define __MINIOS__
is declared, which is set up by the makefile in extras/mini-os.
Suppressing the namespace pollution is necessary to get recent
upstream qemu's to compile, since they (quite properly) use `current'
as an ordinary identifier.

That permits to reduce the amount of difference with upstream.

This adds fixes to the stub domain build into compiling Ian Jackson's
qemu-xen. The most notable change is that mini-os headers now
#include each other through a mini-os/ prefix, so that we can turn all
-I into -isystem and still be sure that we include Mini-OS headers
(and not qemu's console.h or blktaplib's list.h for instance...).

- Move PAGE_SIZE and STACK_SIZE into __PAGE_SIZE and __STACK_SIZE in
arch_limits.h so as to permit getting them from there without
pulling all the internal Mini-OS defines.
- Setup a xen-elf cross-compilation environment in stubdom/cross-root
- Add a POSIX layer on top of Mini-OS by linking against the newlib C
library and lwIP, and implementing the Unixish part in mini-os/lib/sys.c
- Cross-compile zlib and libpci too.
- Add an xs.h-compatible layer on top of Mini-OS' xenbus.
- Cross-compile libxc with an additional xc_minios.c and a few things
disabled.
- Cross-compile ioemu with an additional block-vbd, but without sound,
tpm and other details. A few hacks are needed:
- Align ide and scsi buffers at least on sector size to permit
direct transmission to the block backend. While we are at it, just
page-align it to possibly save a segment. Also, limit the scsi
buffer size because of limitations of the block paravirtualization
protocol.
- Allocate big tables dynamically rather that letting them go to
bss: when Mini-OS gets installed in memory, bss is not lazily
allocated, and doing so during Mini-OS is unnecessarily trick while
we can simply use malloc.
- Had to change the Mini-OS compilation somehow, so as to export
Mini-OS compilation flags to the Makefiles of libxc and ioemu.

Fix x86 arch_switch_thread by making it pure assembly.
There were missing general register clobbers for x86_64, and BP should
theorically be clobbered too, but gcc does not believe that, so the
only simple safe solution is to use pure assembly.

arch/x86/mm.c and arch/x86/sched.c. Header files were also refactored:
arch specific code got moved to include/x86/arch_mm.h and
include/x86/sched_mm.h.
