kvm: Simplify cpu_synchronize_state()
cpu_synchronize_state() is a little unreadable since the 'modified'argument isn't self-explanatory. Simplify it by making it alwayssynchronize the kernel state into qemu, and automatically flush theregisters back to the kernel if they've been synchronized on this...
Check block driver read error in pflash_cfi0x
If a flash file of size smaller than the flash size is specified inthe -pflash option, the block driver returns error. But thepflash_cfi0x ignores the error. This results in a flash content of allzeroes. And the simulation aborts while executing code....

raw-posix: refactor AIO support
Currently the raw-posix.c code contains a lot of knowledge about theasynchronous I/O scheme that is mostly implemented in posix-aio-compat.c.All this code does not really belong here and is getting a bit in theway of implementing native AIO on Linux....
