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.

xs is a too short identifier and does not matche the library. Renaming

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

configuration files to enable or disable the features.

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.

This blocks the main thread indefinitely if there is no PCI backend present in
xenstore.
Even in the case where there are passthrough devices configured libxl creates
the stubdom and waits for it to startup _before_ adding the backend. Since the
stub domains main thread is blocked before it can write the "running" state to
xenstore the toolstack eventually times out and kills everything.
There is already a separate pcifront thread which waits for the backend to
appear and calls init_pcifront at the appropriate time should a backend ever
appear.
Unfortunately I don't have any free test boxes with VT-d so I haven't been able
to test the cases where PCI deivces are passed through but I obviously have
tested that I can now start an HVM domain with stub qemu without PCI devices
passed through which I couldn't do before so this is an improvement. This stuff
is a bit like pushing the lump around the carpet :-/

I'm seeing pvgrub crashing when running CTORs. It appears its because
the magic in the linker script is generating junk. If I get ld to
output a map, I see:
.ctors 0x0000000000097000 0x18
0x0000000000097000 __CTOR_LIST__ = .
0x0000000000097000 0x4 LONG 0x25c04
(((__CTOR_END__ - __CTOR_LIST__) / 0x4) - 0x2)
*(.ctors)
.ctors 0x0000000000097004 0x10
/home/jeremy/hg/xen/unstable/stubdom/mini-os-x86_32-grub/mini-os.o
0x0000000000097014 0x4 LONG 0x0
0x0000000000097018 __CTOR_END__ = .
In other words, somehow ((0x97018-0x97000) / 4) - 2 = 0x25c04
The specific crash is that the ctor loop tries to call the NULL
sentinel. I'm seeing the same with the DTOR list.
Avoid this by terminating the loop with the NULL sentinel, and get rid
of the CTOR count entirely.

Its access controls are really not OK. In particular, it's not good for
libxl, which stores per-VM config blobs in a directory that is exported
to all VMs.
This will break stub-qemu save/restore, which is the only user of
fs-front that I'm aware of, but:
- It's currently broken anyway (fs-back isn't run by default and crashes
if it is run manually); and
- Stefano has a plan to plumb qemu save records through a dedicated
console channel instead.

This patch eliminate the global variables in libxenctrl (used for
logging and error reporting).
Instead the information which was in the global variables is now in a
new xc_interface* opaque structure, which xc_interface open returns
instead of the raw file descriptor; furthermore, logging is done via
xentoollog.
There are three new parameters to xc_interface_open to control the
logging, but existing callers can just pass "0" for all three to get
the old behaviour.
All libxc callers have been adjusted accordingly.
Also update QEMU_TAG for corresponding qemu change.
