We support gluster volumes in domain XML, so we also ought to support them as a storage pool. Besides, a future patch will want to take advantage of libgfapi to handle the case of a gluster device holding qcow2 rather than raw storage, and for that to work, we need a storage backend that can read gluster storage volume contents. This sets up the framework. Note that the new pool is named 'gluster' to match a <disk type='network'><source protocol='gluster'> image source already supported in a <domain>; it does NOT match the <pool type='netfs'><source><target type='glusterfs'>, since that uses a FUSE mount to a local file name rather than a network name. This and subsequent patches have been tested against glusterfs 3.4.1 (available on Fedora 19); there are likely bugs in older versions that may prevent decent use of gfapi, so this patch enforces the minimum version tested. A future patch may lower the minimum. On the other hand, I hit at least two bugs in 3.4.1 that will be fixed in 3.5/3.4.2, where it might be worth raising the minimum: glfs_readdir is nicer to use than glfs_readdir_r [1], and glfs_fini should only return failure on an actual failure [2].
