x86-kvm: only sync SREGS when doing address translation
cpu_synchronize_state is 10x or more expensive on AMD then on intel.
This makes all nand read/writes extremely slow (eg: mounting /system takes
over a minute when KVM is enabled on AMD).
Looking at hw/goldfish* all callers of cpu_synchronize_state want to do
is translate virtual to physical addresses. You can do that with 1 ioctl
(KVM_GET_SREGS). Performance on AMD is significant improved (matching
intel) and intel is not affected.
Converted all callers of cpu_synchronize_state in hw/goldfish-* to sync
over only KVM_GET_SREGS when running in KVM mode.

Changes to existing files to add HAX support
HAX (Hardware-based Accelerated eXecution) employes hardware virtualization
technology to boost performance of the Android emulator on Mac OS X or Windows
hosts.
This changeset includes the changes required to the existing files. To pass
the compilation, hax.h is added, but CONFIG_HAX is disabled so that no
real changes added.

x86: Workaorund for the KVM GS_BASE MSR save/restore issue.
In some versions of the kvm module in Ubuntu, the host's GS_BASE MSR is not save/restored correctly
when running guests on 64-bit hosts if the qemu/emulator is 32-bit.
This patch implements a workaround in the emulator code.

x86: Enable KVM mode for Android x86 emulator (update/rebase)
This patch enables KVM mode on x86 Linux to boost performance of x86 emulaiton
if the hardware-based virtualization feature is present on the host machine.

Merge upstream QEMU 10.0.50 into the Android source tree.
This change integrates many changes from the upstream QEMU sources.
Its main purpose is to enable correct ARMv6 and ARMv7 support to the
Android emulator. Due to the nature of the upstream code base, this
unfortunately also required changes to many other parts of the source.
Note that to ensure easier integrations in the future, some source files
and directories that have heavy Android-specific customization have been
renamed with an -android suffix. The original files are still there for
easier integration tracking, but *never* compiled. For example:
net.c net-android.c
qemu-char.c qemu-char-android.c
slirp/ slirp-android/
etc...
Tested on linux-x86, darwin-x86 and windows host machines.
