script: Use pkh to construct p2pkh output scripts
So far we always needed to know the public key, which was not the case
for addresses that we don't own. Moving the hashing outside of the
script construction allows us to send to arbitrary addresses. I also
added the hash computation to the pubkey primitives.

struct secret: use everywhere.
We alternated between using a sha256 and using a privkey, but there are
numerous places where we have a random 32 bytes which are neither.
This fixes many of them (plus, struct privkey is now defined in terms of
struct secret).

Use global secp256k1_ctx instead of passing it around.
If I'd known how large this patch would be (though trivial), I'd
have done it in parts.

key_from_base58 / pubkey_from_privkey: don't support non-compressed keys.
It just clutters the API, and we don't support them on the wire anyway.

pubkey: don't carry around DER encoding.
We just wrap the libsecp256k1 structure, and convert to DER on demand.

protocol: remove support for uncompressed pubkeys.
There's no good reason to support them, and this way every key is 33 bytes.

bitcoin: hand in a secp256k1_context to all routines.
We don't want to re-create them internally, ever.
The test-cli tools are patched to generate them all the time, but
they're not performance critical.

We still use openssl for bignums (base58) and for ripemd.

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?)
