qemu-block: deprecated/defunct, remove from tree

qemu-block xlator is not used by anyone, or so I'm told.

It's also substantially out of date. There's little reason to keep
it in our sources. (And FedoraProject doesn't like bundled software
either.)

-/* QB_XATTR_KEY_FMT is the on-disk xattr stored in the inode which

-   logic. The value of the key is of the pattern:

-   "format:virtual_size"
-
-   e.g
-
-   "qcow2:20GB" or "qed:100GB"
-
-   The format and virtual size are colon separated. The format is
-   a case sensitive string which qemu recognizes. virtual_size is
-   specified as a size which glusterfs recognizes as size (i.e.,
-   value accepted by gf_string2bytesize())
