Consolidate the function pointer types used by dshash.c.
Commit 8c0d7bafad36434cb08ac2c78e69ae72c194ca20 introduced dshash with hash
and compare functions like DynaHash's, and also variants that take a user
data pointer instead of size. Simplify the interface by merging them into
a single pair of function pointer types that take both size and a user data
pointer.
Since it is anticipated that memcmp and tag_hash behavior will be a common
requirement, provide wrapper functions dshash_memcmp and dshash_memhash that
conform to the new function types.
