Various fixes to mini-os needed to build lwip 1.3.2:
- Don't build the tests.
- Add BSD-style endianness macros to endian.h.
- free() is called via a function pointer so it needs to be a real
function. Do the same for malloc() and realloc().

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.

- xmalloc currently faults if xmalloc_new_page fails due to OOM
- realloc treats xmalloc_hdr.size as the size of just the data region
rather than the total size of data region + headers + padding.

As part of making stubdom usable on NetBSD, it is necessary to
restructure the minios headers to avoid conflicts with NetBSD's
crossbuild toolchain.

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.

It has to check first if the memory to free is so big as to be freed
directly by free_pages. mini-os domains crash without this patch if
vfb is misconfigured.
