[Libvir] [PATCH] Add help to qemu daemon, and a small bug

This patch adds command-line help to the libvirt qemu daemon. One small bug: On my machine at least, QEMUD_PID_FILE is defined as (literally) "${prefix}/var/run/libvirt_qemud.pid". It shouldn't have the "${prefix}" at the beginning, and even if that is fixed it looks like this could result in a path like "/usr/var/run/..." which would be wrong. I fiddled with AC_DEFINE_UNQUOTED and the quoting of the string itself inside configure.in and I couldn't work out how to get the quoting right.
