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.

In order to do so it modifies map_frames_ex and do_map_frames to take
an int *err as parameter and return any error that way.

This is a port of XenLinux xen_alloc_contig_memory() to mini-os. A
sufficiently privileged mini-os guest can exchange a small number of
its pages with machine contiguous pages.

Add ioremap and iounmap functions to minios. Also move some unmapping
code from and clean up mem_test.

allocate_ondemand can be used to allocate addresse space. Primarily
used for mapping MFNs, it can also be used e.g. to map grant refs.

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...).

That permits to stick a bit more to upstream qemu.

- 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.

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.

1. Make Mini-OS start from 0x0.
2. Fixes the pagetable builder to handle half full, but already mapped
pt frames.=20
3. Add a bounds check to ensure than Mini-OS does not try to use Xen
virtual space.
