Newlib unaccountably defines _daylight, _timezone and _tzname, rather
than daylight, timezone and tzname. The latter are specified in
SuSv3.
So do a global search and replace as part of our newlib patching :-(.

In a few places in the tree the Makefiles have constructs like this:
one_file another_file:
$(COMMAND_WHICH_GENERATES_BOTH_AT_ONCE)
This is wrong, because make will run _two copies_ of the same command
at once. This generally causes races and hard-to-reproduce build
failures.
Notably, `make -j4' at the top level will build stubdom libxc twice
simultaneously!
In this patch we replace the occurrences of this construct with the
correct idiom:
one_file: another_file
another_file:
$(COMMAND_WHICH_GENERATES_BOTH_AT_ONCE)

The headers libelf.h and elfstructs.h were removed from
xen/include/public in 19011:7df072566b8c. But this broke the stubdom
build because parts of libxc depend on them. This patch adds
$(XEN_ROOT)/xen/include/xen to the stubdom -I path.

xen-setup runs the upstream configure script, and ends up
autodetecting various properties of the host and then trying to use
them in stubdom, which works badly.
In commit c609854fe18aab3216f28e1e5291b75970d398d5 in
qemu-xen-unstable we provide a new `xen-setup-stubdom' script, which
hardcodes the relevant answers.
With these two changes, stubdom should compile again.

Changeset 19011:7df072566b8c moved some of the libelf headers.
However, no changes were made to stubdom/Makefile.
stubdom/Makefile unfortunately contains embedded in it knowledge about
the header directory structures, and must therefore typically be
updated if new header directories are created.

I have copied the tarballs that the xen-unstable build downloads to
xenbits.xensource.com (which also hosts our hg and git). This patch
changes the download URLs to use that location.
That way the build will depend on only one external machine, under one
administration, rather than many. Also it means that the build won't
break if these sites become permanently unavailable or are rearranged
and we don't run a risk of having to panic and beg if a file should go
missing.

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

While building stubdom, I saw an error.

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

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 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.
