Adds:

  • Generic threshold tree code, and ability to iterate over their allowed combinations and count them.
  • Keytree layer that adds serializable key tree objects (which are threshold trees over public key leaves), and ability to compute their Merkle root and branches in logspace.
  • Human-readable format/parse code for key trees.
  • Signing/ismine code that can cope with key tree outputs.
  • Unit tests for all the above.
  • Wallet/walletdb code to store key trees.
  • RPCs addtreesigaddress and createtreesig.

I'm not sure about this. It has tests. Is that allowed in elements? :P

I tried to remain consistent with the existing style which includes some rudimentary tests. Perhaps these were just a leftover from an older codebase and should be removed?

I'd like to also have this line at the top of ParseKeyTreeCall and at the top of the while loop in that function. That allows to have whitespace before ( and ,.

Whitespace is not very deterministic...

Are you missing a return true here?

Closing; I'd like to use a different implementation, once bitcoin-core/secp256k1#322 is merged.
