Hash_tree_root -> hash_tree_root_internal
...
Clarifies the distinction between "internal" hash roots (may be < 32 bytes for trivial objects) and "external" ones (zpadded to 32).

SSZ list Merkle hashing change
...
The current spec is arguably inconsistent, in that if a set of N values gets chunked into M chunks where M is not an exact power of 2, the chunks between M and next_power_of_2(M) are filled with SSZ_CHUNK_SIZE zero bytes each, but the last chunk is not padded, and could be arbitrarily short (eg. if the values are 4 bytes and there are 257 of them, then that gets serialized into eight chunks chunks where the first four are 64 values each, the fifth is 4 bytes corresponding to the last value, and the last three chunks are SSZ_CHUNK_SIZE zero bytes). This PR fills every chunk up to exactly SSZ_CHUNK_SIZE bytes for consistency.

simplify merkle tree chunking
...
* pack small items tightly to fit more items in single chunk, decreasing
the number of hash operations needed
* remove chunk padding - hash algorithm will pad to its own block size
anyway
* express data length in number of items instead of binary bytes at leaf
level (equivalent)
