chainhash: Abstract hash logic to new package. (#729)

This is mostly a backport of some of the same modifications made in
Decred along with a few additional things cleaned up.  In particular,
this updates the code to make use of the new chainhash package.

Also, since this required API changes anyways and the hash algorithm is
no longer tied specifically to SHA, all other functions throughout the
code base which had "Sha" in their name have been changed to Hash so
they are not incorrectly implying the hash algorithm.

The following is an overview of the changes:

- Remove the wire.ShaHash type
- Update all references to wire.ShaHash to the new chainhash.Hash type
- Rename the following functions and update all references:
  - wire.BlockHeader.BlockSha -> BlockHash
  - wire.MsgBlock.BlockSha -> BlockHash
  - wire.MsgBlock.TxShas -> TxHashes
  - wire.MsgTx.TxSha -> TxHash
  - blockchain.ShaHashToBig -> HashToBig
  - peer.ShaFunc -> peer.HashFunc
- Rename all variables that included sha in their name to include hash
  instead
- Update for function name changes in other dependent packages such as
  btcutil
- Update copyright dates on all modified files
- Update glide.lock file to use the required version of btcutil
