main-loop: add qemu_get_aio_context()

It is very useful to get the main loop AioContext, which is a static

I'm not sure whether qemu_get_aio_context() will be necessary in the
future once devices focus on using their own AioContext instead of the...

host-utils: Use __int128_t for mul[us]64

Replace some x86_64 specific inline assembly with something that
all 64-bit hosts ought to optimize well. At worst this becomes
a call to the gcc __multi3 routine, which is no worse than our
implementation in util/host-utils.c....

cpu: Move current_tb field to CPUState

Explictly NULL it on CPU reset since it was located before breakpoints.

Change vapic_report_tpr_access() argument to CPUState. This also
resolves the use of void* for cpu.h independence.

cpu: Add CPUArchState pointer to CPUState

The target-specific ENV_GET_CPU() macros have allowed us to navigate
from CPUArchState to CPUState. The reverse direction was not supported.
Avoid introducing CPU_GET_ENV() macros by initializing an untyped
pointer that is initialized in derived instance_init functions....

is no longer used.

hbitmap: Use non-bitops ctzl

Both uses of ctz have already eliminated zero, and thus the difference

cpus.c: Drop unnecessary set_cpu_log()

The set_cpu_log() function in cpus.c is a fairly simple wrapper

into vl.c, since there is no need to indirect it via cpus.c
and the handling of the error case is more appropriate to vl.c....
