Andrew Poelstra f906c2fddd Add `first_push_as_number` function to contracthash templates
This is a bit of a hack to let users of the contracthash API to determine
how many sigs are required when signing a multisig contract.

Andrew Poelstra e05e6d2215 [BREAKING CHANGE] Drop UtxoSet
This code was unmaintained, is unlikely to work on the majority of systems
(since it holds the whole utxoset in RAM, and not in a terribly efficient
manner), and has a dependency on `eventual` which has been broken for a
long time.

The library no longer compiles on nightly because of this, and without any
known usecases for `UtxoSet`, nor good ability to test it, I'm simply
removing the code.

I recommend anyone who cares about this extracts the code from the previous
commit and creates a new crate. It should be more featureful anyway, e.g.
support a backing store.

Andrew Poelstra c1993a12c6 Add TxOutRef type to blockdata::transaction; don't use it anywhere in the library itself
This is just a convenience type for the (txid, vout) pairs that get produced
a lot in Bitcoin code. To the best of my knowledge there is nowhere this can
be used in the actual library (in particular, TxOutRef.index is a usize for
convenience while TxIn.prev_index is a u32 for correct consensus encoding,
so there is not redundancy here).

Wladimir J. van der Laan 404176a5ee Fix data leak in CommandString::consensus_encode
A fixed buffer of 12 bytes was unsafely copied from the bytes of a
string - if the string was shorter than that, memory from outside would
leak into the packet.

Replace the unsafe copy by a safe loop. Also add a panic if
an attempt is made to use a command string longer than 12 bytes.

Andrew Poelstra 66eb08aab5 [BREAKING CHANGE] Make `script::Builder` implement the actual Builder pattern
Rather than having methods taking &mut self, have them consume self
and return another Builder, so that methods can be chained.

Bump major version number.

Andrew Poelstra 3491c5057e Make contracthashtool check that the number of keys matches the template's requirement
This is easy to satisfy given that the template-to-script code takes a
slice of keys. Just do &keys[..n_keys] if you have too many keys. (If
you have too few you're SOL no matter what.) This way we can catch
likely configuration errors without putting much of a burden on users
who legitimately have more keys than the template requires.

Also add a method required_keys() to Template so that users can check
how many keys they ought to have.

Andrew Poelstra fdc854edd9 Remove Script() from LowerHex impl of Script
This is easy for downstream to add, not easy for them to remove. Plus scripts
have a pretty recognizable form and are usually obvious from context anyway.

Andrew Poelstra ed34bb30f1 Add support for deserializing a script into a contracthash template
This is something Matt's contracthashtool does, so to copy its functionality
I need to support it. And it also seems generally useful.

Andrew Poelstra 16e2a3519b Implement basic contract-hash support
Does not do stuff like validating the form of contracts, since this seems like
more of an application thing. Does not even distinguish a "nonce", just assumes
the contract has whatever uniqueness is needed baked in.
