hw: move headers to include/

Many of these should be cleaned up with proper qdev-/QOM-ification.
Right now there are many catch-all headers in include/hw/ARCH depending
on cpu.h, and this makes it necessary to compile these files per-target.
However, fixing this does not belong in these patches....

block: fix I/O throttling accounting blind spot

I/O throttling relies on bdrv_acct_done() which is called when a request
completes. This leaves a blind spot since we only charge for completed
requests, not submitted requests.

For example, if there is 1 operation remaining in this time slice the...

cpu: Move halted and interrupt_request fields to CPUState

Both fields are used in VMState, thus need to be moved together.
Explicitly zero them on reset since they were located before
breakpoints.

cpu: Register VMStateDescription through CPUState

In comparison to DeviceClass::vmsd, CPU VMState is split in two,

Therefore add a CPU-specific CPUClass::vmsd field.

Unlike the legacy CPUArchState registration, rather register CPUState....

There is no reason for outgoing exec migration to do popen manually
