a8db4dc31f qemuVirtioFSStop: Simplify daemon kill
Now, that we know that the virtiofsd will have the pidfile open
and locked we can use virPidFileForceCleanupPath() to kill it and
unlink the pidfile.

7055af6c22 qemu: virtiofs: shorten pid filename
There is no need to repeat the shortName, since it's
already present in the directory path.

Also use just 'fs' instead of 'virtiofsd'.

071a1ab92f qemu: use the vhost-user schemas to find binary
Look into /usr/share/qemu/vhost-user to see whether we can find
a suitable virtiofsd binary, in case the user did not provide one
in the domain XML.

f0f986efa8 qemu: add code for handling virtiofsd
Start virtiofsd for each <filesystem> device using it.

Pre-create the socket for communication with QEMU and pass it
to virtiofsd.

Note that virtiofsd needs to run as root.
