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.

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.

Remove compiler warnings when building the emulator. This forces -Wall during the build. Note that this patch doesn't remove all warnings, but most of the remaining ones are from upstream anyway. Change-Id: I8808d8495e99866e156ce5780d2e3c305eab491f

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.
