daemon: Export SDL audio environment variables
/etc/sysconfig/libvirtd has a few environment variables for configuring
libvirt SDL audio. The libvirtd process doesn't see these, however, because
they are never exported. Let's export the variables after sourcing the
sysconfig script.
There is another problem here that the commented out values in the
sysconfig script are not neccessarily the actual defaults, we are qemus
mercy here. Not sure how to solve that.

qemu: Allow using regular audio backends with VNC
Currently all host audio backends are disabled if a VM is using VNC, in
favor of the QEMU VNC audio extension. Unfortunately no released VNC
client supports this extension, so users have no way of getting audio
to work if using VNC.
Add a new config option in qemu.conf which allows changing libvirt's
behavior, but keep the default intact.
v2: Fix doc typos, change name to vnc_allow_host_audio

network: bridge: Don't start network if it collides with host routing
Fedora bug https://bugzilla.redhat.com/show_bug.cgi?id=235961
If using the default virtual network, an easy way to lose guest network
connectivity is to install libvirt inside the VM. The autostarted
default network inside the guest collides with host virtual network
routing. This is a long standing issue that has caused users quite a
bit of pain and confusion.
On network startup, parse /proc/net/route and compare the requested
IP+netmask against host routing destinations: if any matches are found,
refuse to start the network.
v2: Drop sscanf, fix a comment typo, comment that function could use
libnl instead of /proc
v3: Consider route netmask. Compare binary data rather than convert to
string.
v4: Return to using sscanf, drop inet functions in favor of virSocket,
parsing safety checks. Don't make parse failures fatal, in case
expected format changes.
v5: Try and continue if we receive unexpected. Delimit parsed lines to
prevent scanning past newline

commit 07f6c3a95f1caca368c8723b5b0a25ae2faa1ffe
Author: David Allan <dallan@redhat.com>
Date: Thu May 27 10:44:02 2010 -0400
v2 of Cole's wlan support
* Incorporated Jim's feedback (v1 & v2)
* Moved case of DEVTYPE == "wlan" up as it's definitive that we have a network interface.
* Made comment more detailed about the wired case to explain better
how it differentiates between wired network interfaces and USB
devices.
