Subject: [PATCH] cpu: Move CPU_COMMON_THREAD into CPUState
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

CPU_COMMON_THREAD was only used for Windows, adding an hThread field
to CPU_COMMON.

Move the field into QOM CPUState and change its type to HANDLE,
which it is assigned from. This requires Windows headers, pulled in
through qemu-thread.h.
