Modify Keyed_Filter so it is a pure interface

Modify ECB to use parallel encryption/decryption where possible

Add toggles in build.h specifying how many blocks to process in parallel.
Defaults to 8 blocks for all modes, which is sufficient that any likely
parallelism can be extracted (via SIMD or concurrent execution) but not
so much as to seem likely to cause cache problems (8*128 bits = 128 bytes,
or two x86 cache lines)
