arm_boot: Change initrd load address to "halfway through RAM"

to account for larger kernel images, put the initrd halfway
through RAM. This allows large kernels on new boards with lots

boards with only 32MB of RAM.

Note that this change fixes in passing a bug where we were
passing an overly large max_size to load_image_targphys()
for the initrd, which meant that we wouldn't correctly refuse

Second is the current server's view of the screen content.  The vnc code

surface gets replaced by a pixman image.  The format changes too,
instead of using the guest screen format we'll use fixed 32bit rgb
framebuffer and convert the pixels on the fly when comparing and
updating the server framebuffer.

Third surface carries the format expected by the vnc client.  That isn't
used to store image data.  This surface is switched to PixelFormat and a
boolean for bigendian byte order.

raw-win32: implement native asynchronous I/O

With the new support for EventNotifiers in the AIO event loop, we
can hook a completion port to every opened file and use asynchronous
I/O on them.

Wine's support is extremely inefficient, also because it really does
the I/O synchronously on regular files. (!)  But it works, and it is
good to keep the Win32 and POSIX ports as similar as possible.

Paolo Bonzini [Thu, 23 Feb 2012 12:23:34 +0000 (13:23 +0100)]
aio: add generic thread-pool facility

Add a generic thread-pool.  The code is roughly based on posix-aio-compat.c,
with some changes, especially the following:

- use QemuSemaphore instead of QemuCond;

- separate the state of the thread from the return code of the worker
function.  The return code is totally opaque for the thread pool;

- do not busy wait when doing cancellation.

A more generic threadpool (but still specific to I/O so that in the future
it can use special scheduling classes or PI mutexes) can have many uses:
it allows more flexibility in raw-posix.c and can more easily be extended
to Win32, and it will also be used to do an msync of the persistent bitmap.
