Add support for custom backend metadatabackend_metadata_adder
A backend may have the need to add custom metadata to the
encoded data/parity fragments, in addition to the
liberasurecode "fragment metadata headers". This patch
gives the ability to a EC backend writer to specify a
"metadata adder" that is taken into account when allocating
output data/parity fragment buffers.
