Many ciphers perform better when allowed to operate on data sizes that are
larger than the natural block size of the algorithm.
This patch adds a struct member .cia_interleave which holds the preferred
number of blocks processed in a single invocation. The invocations themselves
should occur through .cia_enc_interleave and .cia_dec_interleave.
