[Qemu-devel] [PATCH v2 00/13] allow tools to use the QEMU main loop

[Paolo Bonzini <pbonzini@redhat.com>]

This patch series makes the QEMU main loop usable out of the executable,
and especially in tools and possibly unit tests.  The series already
starts using the refactored main loop in qemu-nbd.

This is cleaner because it avoids introducing partial transitions to
GIOChannel.  Interfacing with the glib main loop is still possible.

The main loop code is currently split in cpus.c and vl.c.  Moving it
to a new file is easy; the problem is that the main loop depends on the
timer infrastructure in qemu-timer.c, and that file currently contains
the implementation of icount and the vm_clock.  This is bad for the
perspective of linking qemu-timer.c into the tools.  Luckily, it is
relatively easy to untie them and move them out of the way.  This is
what the largest part of the series does (patches 1-9).

Patches 10-13 complete the refactoring and cleanup some surrounding
code.
