Similar to xenbus_read_integer, this function reads a xenstore path
and parses it as a uuid. See include/xenbus.h for details.

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.

When xenbus_switch_state has to retry the transaction which it just
created, it needs to recreate another one. Clearing xbt triggers it.

The return value of Xenbus routines xenbus_transaction_start(),
xenbus_printf(), xenbus_transaction_end(), etc. is a pointer of error
message. This pointer should be passed to free() to release the
allocated memory when it is no longer needed.

this patch implements dynamic connections and disconnections in
pcifront.
This feature is required to properly support pci hotplug, because when
no pci devices are assigned to a guest, xend will remove the pci
backend altogether.

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.

evtchn_bind_interdomain used to clear any already pending event before
binding a handler, because else the handler may be called before it is
ready. That however leads to missed events, which I had to workaround
for the HVM case.
This changes the semantics of bind_evtchn, and thus of all the
event channel binding functions (bind_virq, evtchn_alloc_unbound,
evtchn_bind_interdomain) into not unmasking the event itself, hence
letting the caller initialize properly before unmasking the port (e.g.
record the port number in an appropriate place).

version compiles and starts up, but I'm not really sure how to test the new
xenbus implementation.
* Added unbind_evtchn
* Copied parts of the Linux spinlock implementation to make the changes to
xenbus compared to Linux smaller. Also added a dummy rwsem implementation.
* Updated the xenbus-files

is pretty big, but this is mostly because I've replaced hypervisor.h with the
hypercalls.h header file from Linux (which seems easier to maintain
anyway). I've ignored X86_64.
