Andrew Poelstra 8e7d763310 Parallelize transaction verification in utxoset
We no longer confirm that chained transactions occur in the correct order
in blocks, which is a minor consensus regression and should be dealt with
in future.

Andrew Poelstra ecdb750148 Implement script except for crypto opcodes, replace zero_hash by Default
Looks like to implement the crypto opcodes I may need to switch from
rust-crypto to rust-openssl.. or implement RIPEMD-160 for rust-crypto.
In either case I will need to generalize the hash.rs stuff to support
other hashes, so I'm committing here as a checkpoint before doing all
that.

Andrew Poelstra 2986e1f983 Fix for new partial-move rules; swap hash le_hex_string and be_hex_string
I noticed that the little/big endian hex string functions for Sha256dHash
did not match my intuition. What we should have is that the raw bytes
correspond to a little-endian representation (since we convert to Uint256
by transmuting, and Uint256's have little-endian representation) while
the reversed raw bytes are big-endian.

This means that the output from `sha256sum` is "little-endian", while the
standard "zeros on the left" output from bitcoind is "big-endian". This
is correct since we think of blockhashes as being "below the target" when
they have lots of zeros on the left, and we also notice that when hashing
Bitcoin objects with sha256sum that the output hashes are always reversed.

These two functions le_hex_string and be_hex_string should really not be
used outside of the library; the Encodable trait should give access to a
"big endian" representation while ConsensusEncodable gives access to a
"little endian" representation. That way we describe the split in terms
of user-facing/consensus code rather than big/little endian code, which
is a better way of thinking about it. After all, a hash is a collection
of bytes, not a number --- it doesn't have an intrinsic endianness.

Oh, and by the way, to compute a sha256d hash from sha256sum, you do

  echo -n 'data' | sha256sum | xxd -r -p | sha256dsum

Andrew Poelstra 474d04d154 Manually implement Encodable/Decodable/Show for Network
Since TOML will not encode C-like enums as strings, we do it
ourselves. This is also worthwhile so that we can get the
lowercase "bitcoin" and "testnet" as encodings for the actual
enum values, which are more verbose and camel case.

Andrew Poelstra a6eb33efd0 Actually encode network message
A pretty serious oversight :) this was not noticed because I was
simultaneously dealing with a serious tcp connection bug in rustc,
and I had thought bitcoind's angry disconnects were a further
symptom of that.

Andrew Poelstra a2ce000b2b Revamp Serializable interface to be similar to Encoder/Encodable
This is a massive simplification, fixes a couple endianness bugs (though
not all of them I don't think), should give a speedup, gets rid of the
`serialize_iter` crap.
