ioemu: actually check for errors in bdrv_flush et al
bdrv_flush is declared to return void, but this is wrong because it

Indeed, the implementations generally ignore errors.
This patch corrects this by making it return int (implicitly, either 0
or -errno, as for other similar functions). All of the
implementations and callers are adjusted too.

x86: stub domains and page ownership for mapping in dom0
In the case of an ioemu stubdomain with SDL or vnc server running in
dom0, we want to have the stubdomain expose the HVM guest's video RAM
through PVFB.
However, to map the pages from dom0, xenfb uses xc_map_foreign_pages
with the stubdomain ID as domid (since that is what is advertised in
the PVFB protocol, and needed for other parts of the protocol), and
thus get_page_from_l1e() complains because the stubdomain is not the
owner of the pages. In such case, this patch checks that the
stubdomain has privileges on the actual owner of the pages, and then
accept the mapping.

x86: fix feature availability for PV guests
PV guests should not be allowed to believe features not currently
virtualized (in many cases, requiring special MSRs) are available. Of
course it is bad enough that to work on older hypervisors guests will
still need to special case this, but better fix it now than never.

ioemu: SDL rendering using OpenGL
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).
