[libvirt] [PATCH 4/4] Add support for qemu's guestfwd



This patch allows the following to be specified in a qemu domain:

<channel type='pipe'>
  <source path='/tmp/guestfwd'/>
  <target type='guestfwd' address='10.0.2.1' port='4600'/>
</channel>

This will output the following on the qemu command line:

-chardev pipe,id=channel0,path=/tmp/guestfwd \
-net user,guestfwd=tcp:10.0.2.1:4600-chardev:channel0

* docs/schemas/domain.rng: Add <channel> and <guestfwd> elements
* proxy/Makefile.am: add network.c as dep of domain_conf.c
* src/conf/domain_conf.[ch]: Add xml parsing/formatting for channel and guestfwd
* src/qemu/qemu_conf.c: Add argument output for guestfwd
* tests/qemuxml2(argv|xml)test.c: Add test for guestfwd domain syntax
