Peter Crosthwaite ae1f36f12b cpus: Don't kick un-realized cpus. 
following a464982499, it's now possible for
there to be attempts to take the BQL before CPUs have been realized in
cases where a machine model inits peripherals before the first CPU.

BQL lock aquisition kicks the first_cpu, leading to a segfault if this
happens pre-realize. Guard the CPU kick routine to perform no action for
a CPU that doesn't exist or doesn't have a thread yet.

There was a fix to this with commit
6b49809c59, but the check there misses
the case where the CPU has been inited and not realized. Strengthen the
check to make sure that the first_cpu has a thread (i.e. it is
realized) before allowing the kick.

Paolo Bonzini c5d92c871f cpus: be more paranoid in avoiding deadlocks 
For good measure, ensure that the following sequence:

   thread 1 calls qemu_mutex_lock_iothread
   thread 2 calls qemu_mutex_lock_iothread
   VCPU thread are created
   VCPU thread enters execution loop

results in the VCPU threads letting the other two threads run
and obeying iothread_requesting_mutex even if the VCPUs are
not halted.  To do this, check iothread_requesting_mutex
before execution starts.

Paolo Bonzini 620f0af8d5 cpus: fix deadlock and segfault in qemu_mutex_lock_iothread 
When two threads (other than the low-priority TCG VCPU thread)
are competing for the iothread lock, a deadlock can happen.  This
is because iothread_requesting_mutex is set to false by the first
thread that gets the mutex, and then the VCPU thread might never
yield from the execution loop.  If iothread_requesting_mutex is
changed from a bool to a counter, the deadlock is fixed.

However, there is another bug in qemu_mutex_lock_iothread that
can be triggered by the new call_rcu thread.  The bug happens
if qemu_mutex_lock_iothread is called before the CPUs are
created.  In that case, first_cpu is NULL and the caller
segfaults in qemu_mutex_lock_iothread.  To fix this, just
do not do the kick if first_cpu is NULL.
