While thinking about this today I realized it is actually quite a rat hole. I 
started by making a list of tasks associated with the rename

- Replace 'libxl' with 'xen' in the docs
- Change configure option to '--with-xen' and drop '--with-libxl'
- Rename virt-driver-libxl.m4 to virt-driver-xen.m4
- Rename src/libxl to src/xen
- Rename src/xen/libxl_*.[ch] to src/xen/xen_*.[ch}
- Rename all the libxl files under tests/

These are easy enough, but should the list continue with renaming functions in 
all those files? And what about things that are not so easy to rename, e.g. 
runtime directories such as /etc/libvirt/libxl, /var/lib/libvirt/libxl/, 
/var/log/libvirt/libxl, etc. Would renaming some things but leaving others cause 
more confusion than the current situation?

Regardless of how far to go with renaming libxl to xen, I think moving the 
xen<->libvirt config converter files from src/xenconfig to src/libxl and nuking 
the xenconfig directory is a worthy endeavor.
