Xen was left behind when CpusAccel became mandatory and fails the assert
in qemu_init_vcpu(). It relied on the same dummy cpu threads as qtest.
Move the qtest cpu functions to a common location and reuse them for
Xen.
v2:
New patch "accel: Remove _WIN32 ifdef from qtest-cpus.c"
Use accel/dummy-cpus.c for filename
Put prototype in include/sysemu/cpus.h

Xen was broken by commit 1583a3898853 ("cpus: extract out qtest-specific
code to accel/qtest"). Xen relied on qemu_init_vcpu() calling
qemu_dummy_start_vcpu() in the default case, but that was replaced by
g_assert_not_reached().
Add a minimal "CpusAccel" for Xen using the dummy-cpus implementation
used by qtest.

Thank you, Paolo. Also Anthony Acked and Claudio Reviewed patch 3.
How can we get this into the tree?

Since Anthony acked patch 3, I think I can also take it through the qtest tree.
