38d8f5c84e exec: Return CPUState from qemu_get_cpu()
Move the declaration to qemu/cpu.h and add documentation.
The implementation still depends on CPUArchState for CPU iteration.

b2a8658ef5 protect the ramlist with a separate mutex
Add the new mutex that protects shared state between ram_save_live
and the iothread.  If the iothread mutex has to be taken together
with the ramlist mutex, the iothread shall always be _outside_.

f798b07f51 add a version number to ram_list
This will be used to detect if last_block might have become invalid
across different calls to ram_save_live.

0d6d3c87a2 exec: change ramlist from MRU order to a 1-item cache
Most of the time, only 2 items will be active (from/to for a string operation,
or code/data).  But TCG guests likely won't have gigabytes of memory, so
this actually goes down to 1 item.
