cpus: Access CPUState::thread_kicked atomically
cpus_kick_thread() is called via cpu_exit() -> qemu_cpu_kick(),
and also via gdb_syscall_handling(). Access the CPUState field
using atomic accesses. See commit 8ac2ca02744 ("accel: use atomic
accesses for exit_request") for rationale.

bql: Fix bql_locked status with condvar APIs
QEMU has a per-thread "bql_locked" variable stored in TLS section, showing
whether the current thread is holding the BQL lock.
It's a pretty handy variable. Function-wise, QEMU have codes trying to
conditionally take bql, relying on the var reflecting the locking status
(e.g. BQL_LOCK_GUARD), or in a GDB debugging session, we could also look at
the variable (in reality, co_tls_bql_locked), to see which thread is
currently holding the bql.
When using that as a debugging facility, sometimes we can observe multiple
threads holding bql at the same time. It's because QEMU's condvar APIs
bypassed the bql_*() API, hence they do not update bql_locked even if they
have released the mutex while waiting.
It can cause confusion if one does "thread apply all p co_tls_bql_locked"
and see multiple threads reporting true.
Fix this by moving the bql status updates into the mutex debug hooks. Now
the variable should always reflect the reality.

rx: cpu: fix interrupts check in rx_cpu_do_interrupt()
Commit 87511341c30 broke interrupt handling, replacing interrupts
fetch with a bool and then the remaining code attempting to check
individual bits on that bool value, which effectively masked those
interrupts.
Fix it by checking individual interrupt bits directly instead of
old 'fetch then check' approach.
Fixes: 87511341c30d ("add cpu_test_interrupt()/cpu_set_interrupt() helpers and
use them tree wide")

Add IgvmNativeVpContextX64 struct holding the register state (see igvm
spec), and the qigvm_x86_load_context() function to load the register
state.
Wire up using two new functions: qigvm_x86_set_vp_context() is called
from igvm file handling code and stores the boot processor context.
qigvm_x86_bsp_reset() is called from i386 target cpu reset code and
loads the context into the cpu registers.
