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.

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).

XenAPI defines the platform attribute of a VM as a string-string map
but in various code paths in xend the platform entries are expected to be
another type, e.g. int. This patch defines the types of each platform
entry and converts the entry values to appropriate type when new domU
configuration is created via XenAPI.
Alternatively the values could be casted to appropriate type when used
but seems prudent to do the conversion when domU configuration is
created.

When creating a rfb console via XenAPI the device model is not being
set to qemu-dm, resulting in no pvfb since qemu-dm is not launched
when domU is started. This patch sets device model when a rfb console

Many of the new domU config options related to hvm guests (e.g. hpet,
rtc_timeoffset, etc.) are not initialized with default values via
XenAPI, which prevents starting an hvm domU created through XenAPI.
This patch ensures the new options are set with appropriate default
values in XendConfig platform sanity check.

Add support for a tap:ioemu pseudo driver. Devices using this driver
won't use tapdisk (containing the code duplication) any more, but will
connect to the qemu-dm of the domain. In this way no working
configuration should be broken right now as you can still choose to
use the tapdisk drivers.

We cannot currently change cpu affinity definitions of inactive
managed domains by xm vcpu-pin command. This patch enables changing
cpu affinity definitions of inactive managed domains. However, we
cannot change cpu affinity definitions to each vcpu because we cannot
currently define cpu affinity definitions to each vcpu to domain
configuration definitions. Therefore, we need to specify 'all' to

Right now qemu takes care of converting pixels between the guest pixel
format and the sdl pixel format, after that qemu also memcpy the
converted pixels to the sdl buffer in video ram. This process can be
improved using the SDL blit capabilities: the patch I am attaching
creates an SDL Surface from the Cirrus VGA framebuffer and uses SDL
blitting functions to convert and write pixels to video ram. SDL
blitting functions are optimized and can even be hardware accelerated
on some platforms.
