[libvirt] [PATCH 0/2] Filesystem pool probing & filesystem building

The following patches add support for building a filesystem on the source device when building a filesystem pool. The first patch adds mkfs and libblkid to the build system. The second patch adds two flags to virStorageBackendFileSystemBuild. The first flag causes the build operation to probe for an existing filesystem of the type specified in the pool XML. If an existing filesystem of the specified type is present, mkfs is not executed and the build call returns an error. Any other data present on the source device will be overwritten. The second flag causes the build to execute mkfs unconditionally overwriting whatever is currently on the source device. Calling virStorageBackendFileSystemBuild without any flags preserves the current behavior, which is to make the directory on which the filesystem will be mounted, but to leave the source device untouched.
