  1. colblk: add a KeySchema-specific header 

    We add a fixed-size KeySchema-specific header to the beginning of the
custom block header. A KeySchema implementation can store there
information and retrieve it when initializing the key seeker.

We use this to add a byte to cockroach blocks which indicates what
types of suffixes are contained in the block (mvcc, empty, non-mvcc).
This will be used for optimized fast paths for the common cases.
