bitcoin_script: fix out-by-one error in multisig.
Was using 3 instead of 2. OP_LITERAL() was a bad idea anyway,
as it would only handle numbers up to 16 (and we use 32).

This exits status 1 and prints to stderr.

Use pubkey structures in bitcoin_script, rather than protobufs.
This ensures we do checking beforehand, and keeps abstractions clear.

Make an explicit bitcoin_txid() call.
Neater than open-coding it. We still need the raw version for
signatures though.

Explicit pubkey structure.
This checks that the protobuf is the right form, also handles uncompressed
keys (though you shouldn't be using those any more, should you?)

Use raw 64-byte signatures in protocol.
DER encoding introduces problems for non-canonical encodings; we should
do that only at the lightning<->bitcoin interface.
