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().

This patch adds 3 new drivers to mini-os.
tpmfront - paravirtualized tpm frontend driver
tpmback - paravirtualized tpm backend driver
tpm_tis - hardware tpm driver
Unfortunately these drivers were derived from GPL
licensed linux kernel drivers so they must carry
the GPL license. However, since mini-os now
supports conditional compilation, hopefully these
drivers can be included into the xen tree and
conditionally removed from non-gpl projects.
By default they are disabled in the makefile.

This adds compile-time logic to disable certain frontends in mini-os:
- pcifront is disabled by default, enabled for ioemu
- blkfront, netfront, fbfront, kbdfront, consfront are enabled by default
- xenbus is required for any frontend, and is enabled by default
If all frontends and xenbus are disabled, mini-os will run without
needing to communicate with xenstore, making it suitable to run the
xenstore daemon. The console frontend is not required for the initial
console, only consoles opened via openpt or ptmx.

Instead of using CONFIG_QEMU and CONFIG_GRUB to enable or disable minios
code, create CONFIG_ items for features and use application-specific
configuration files to enable or disable the features.
The configuration flags are currently added to the compiler command
line; as the number of flags grows this may need to move to a header.

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.

Otherwise make can search the path relative to certain standard paths
such as /usr/include (e.g., the line '-include $(XEN_ROOT)/.config' in
Config.mk suffers from this).

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.

Allow extra application objects to be linked against a partial link of
minios with non-global names localised. For now we assume that global
names ill be assigned a xenos_ prefix in due course. We may decide to
choose a different prefix.
Those who wish to finish the link from an external Makefile can link
their own objects against mini-os.o (which must be first in link
order!) and specify the appropriate architecture linker script.
