Attached patch adds dynamic frame buffer size support to the xenfb PV
backend QEMU xenfb. Backend sets feature-resize and handles the
resize frame buffer event.
Corresponding frontend LINUX patch is required for functionality but
this patch is not dependent on it, preserving backwards
compatibility.

Some versions of Windows 2000 only support no more than 15 cpus in
ACPI table, otherwise it will cause a BSOD
KMODE_EXCEPTION_NOT_HANDLED. This patch decrease the cpu count in the
ACPI DSDT to 15.

Even if we don't need to tell the client to redepth, we need to tell
e.g. xenfb that we can't share the buffer any more.

With some combinations of compiler flags (no optimization, -Werror),
the compiler may complain that the function doesn't have a return
statement (even if the function actually just never returns), reported
as bug 1128. This adds a dummy return statement.

This patch fixes methods in SrvDomain class for inactive managed

to the missing UUID. This patch fixes this.

Add opengl support for rendering the guest framebuffer in the SDL
window. SDL is needed anyway to open the window and handle the
events. Opengl rendering is optional and can be turned off at both
compile time and in the vm configuration file.
Some of the benefits of using opengl are:
- faster rendering, less CPU intensive, especially with good graphic
cards;
- makes the window resizing possible and hardware accelerated, thus
very efficient and smooth;
- allows other optimizations like sharing directly a buffer in vram
with the guest (not yet implemented).

When I stopped xend by xend stop command, a domain suspend processing
is frequently failed. This patch solves the problem.
Step to reproduce:
1. xm new XXX on_xend_stop="suspend"
2. xm start XXX
3. xend stop
In the xend stop, if the domain suspend processing is slept by
state_updated.wait() of waitForShutdown(), then the domain suspend
processing is not waked up again because state_updated.notifyAll()
of _stateSet() is not executed.
For the reason, processing of _on_domains_changed() is waited by
domains_lock.acquire() because the domain suspend processing is
keeping domains_lock and sleeping. The domain suspend processing
got domains_lock at cleanup_domains().

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).
