Replace the stubdom/ioemu link farm creation in stubdom/Makefile,
with code which arranges that:
* No symlinks are made for output files - in particular, any
symlinks for .d files would be written through by the compiler
and cause damage to the original tree and other strange
behaviours
* All subdirectories are made as local subdirectories rather than
links
* Any interrupted or half-completed creation of the link farm
leaves the directory in a state where the link farming will be
restarted
* We use make's inherent ability to test for the existence of files
rather than using [ -f ... ] at the start of the rule's commands
* The list of files to be excluded from the link farm can be
easily updated
etc.
This should fix some problems particularly with parallel builds,
or by-hand builds where directories are entered in other than the
usual order.

* Move code for generating an absolute version of XEN_ROOT
into a common make variable set in Config.mk
* Use this common code when invoking make -C ioemu-dir clean
from tools/, which avoids a problem where `make clean' fails
because qemu's (ioemu-remote's) build system wants to run
`make clean' in `tests' but XEN_ROOT is a confection involving
../'s.
* Use this common code in stubdom/Makefile, instead of $(abspath...)
as the latter is a relatively new feature in GNU make and is not
available in all the places that we want to be able to build
(cf c/s 17997:3f23e01d31985899dbd1660b166f229f1ee74292)

We can decide to make off_t 64bit instead of implementing the LFS
tricks. Name corresponding functions foo64 to permit simple caml
programs linking.

While building stubdom, I saw an error.
install: cannot stat `lib/{config,header,pci,types}.h': No such file
or directory
It seems brace expansion is not available in some environments, so we
had better avoid using it.

make should not have to regenerate the libxc and ioemu directories
since that is part of the mk-headers target. Use the subdirectory
clean targets instead to clean just the object files.

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...).

This makes stubdom use the host's gcc instead of downloading/compiling
binutils+gcc. That requires a bunch of changes and even uncovered a
few bugs, but saves a lot of time.

This fetches GRUB1 sources, applies the {graphical, print function,
save default, and ext3_256byte} patches from debian, and applies a
patch to make it work on x86_64 and port it to Mini-OS. By using
libxc, PV-GRUB can then "kexec" the loaded kernel from inside the
domain itself, hence permitting to avoid the security-concerned
pygrub.
