[Sheng Yang <sheng@linux.intel.com>]

Change from v4:
1. Rebased on latest KVM
2. Fix minor comments.
3. Drop big-endian patch because unable to guarantee the correctless. Add TODO for it.

Change from v3:
1. Re-design the userspace API.
2. Add big-endian support for msix_mmio_read/write()(untested!)

Change from v2:
1. Move all mask handling to kernel, and userspace has to access it using API.
2. Discard userspace mask bit operation API.
