To support live migration, we override QEMUFile so that instead of writing to
disk, the save/restore state happens over a network connection.

This patch makes QEMUFile read/write operations function pointers so that we
can override them for live migration.

the CPUID specification. This patch addresses this by specifying exactly 
what is missing.
While going along the missing CPUID entries I also stumbled across 
invalid and missing CPUID #defines while comparing them to the Intel 
Documentation. This patch also addresses these. I found them too minor 
to split them up in a separate patch.

Furthermore I looked through CPUID functions > 5 and realized that it 
should be safe to bump the level to 10. I tried booting Linux with that 
and it worked fine.

This does the reverse of bt-host.c, proxying from guest to host.

This implements most of the logic of a real HCI (at least the pieces
marked as mandatory).  It doesn't support keys, authentication etc.
It works on top of the LMP layer, which is not fully emulated because
software never has direct access to it.

This allows using a host's physical HCI as one of the HCIs attached
to the virtual machine.  This brings various limitations because not
all commands/events are passed through by Linux kernel, some are
interpreted by the host's kernel for a speed gain.

Instead of having (current)three command line switches -std-vga,
-cirrusvga and -vmwarevga, provide one -vga switch which takes
an argument, so that:
qemu -std-vga   becomes qemu -vga std
qemu -cirrusvga becomes qemu -vga cirrus
qemu -vmwarevga becomes qemu -vga vmware

Update documentation accordingly.

Be more friendly when signalfd() fails, and also add configure checks to detect
that syscall(SYS_signalfd) actually works.  malc pointed out that some installs
do not have /usr/include/linux headers that are in sync with the glibc headers
so why SYS_signalfd is defined, it's #defined to _NR_signalfd which is not
defined in the /usr/include/linux header.

While this is a distro bug, it doesn't hurt to do a more thorough job in
detection.

This patch implements a simple fd pool to allow many AIO requests with
posix-aio.  The result is significantly improved performance (identical to that
reported for linux-aio) for both cache=on and cache=off.

The fundamental problem with posix-aio is that it limits itself to one thread
per-file descriptor.  I don't know why this is, but this patch provides a simple
mechanism to work around this (duplicating the file descriptor).

This isn't a great solution, but it seems like a reasonable intermediate step
between posix-aio and a custom thread-pool to replace it.

Ryan Harper will be posting some performance analysis he did comparing posix-aio
with fd pooling against linux-aio.  The size of the posix-aio thread pool and
the fd pool were largely determined by him based on this analysis.

__GLIBC_PREREQ is defined in such a way that the ! cannot be used in front of
it on FreeBSD.  Also, -lpthread is not implied by the build and we definitely
use it for compatfd support.

While at it, I added a default initialization for posix-aio that seems to
perform well in our testing.

This patch adds a Core 2 Duo CPU to the available CPU types. The CPU
definition tries to resemble a real CPU as good as possible, whilst not
exposing features qemu does not implement.
The patch also includes some minor additions that Core 2 Duo CPUs have:

- New MSR: MSR_IA32_PERF_STATUS
- CPUID up to level 5 (cache info and mwait)

During the debugging of the new revision of the zero dedup patch I
stepped on the following bug in block-qcow2.c:alloc_cluster_offset(). I
am not sure what the exact damage this bug can do, but it may be very
nasty because you way not notice it effects until you will do some
snapshot operations or similar actions that rely on the reference
counting.

The bug is easy to spot using the new "check" verb I added to the
qemu-img in one of the previous patches. I will resend the qemu-img
patch again with the new version of the zero dedup.
