This patch combines qtest and -icount together to turn the vm_clock
into a source that can be fully managed by the client. To this end new
commands clock_step and clock_set are added. Hooking them with libqtest
is left as an exercise to the reader.

After the removal of the non-threaded mode cpu_exec_all is now only used
by TCG. Refactor it accordingly, also dropping its unused return value.

Add command line support for logging to a location other than /tmp/qemu.log.
With logging enabled (command line option -d), the log is written to
the hard-coded path /tmp/qemu.log. This patch adds support for writing
the log to a different location by passing the -D option.

Instead of fiddling with debug_requested and vmstop_requested directly,
introduce qemu_system_debug_request and turn qemu_system_vmstop_request
into a public interface. This aligns those services with exiting ones in
vl.c.

If some I/O operation ends up calling qemu_system_reset_request in VCPU
context, we record this and inform the io-thread, but we do not
terminate the VCPU loop. This can lead to fairly unexpected behavior if
the triggering reset operation is supposed to work synchronously.
Fix this for TCG (when run in deterministic I/O mode) by setting the
VCPU on stop and issuing a cpu_exit. KVM requires some more work on its
VCPU loop.

These functions are also used for kvm under !CONFIG_IOTHREAD, having
'tcg' in their name is just misleading.
