19769ba6c5 Auto merge of #976 - ebfull:implement-joinsplit-signatures, r=ebfull 
Signing pours with ed25519

This is an alternative to #964 which uses ed25519 instead of secp256k1, and avoids the separate hash for fitting the public key into the `h_sig` block. It's based on @defuse's work in that branch.

Closes #808.

212cdc4fa4 Auto merge of #972 - bitcartel:zc.v0.11.2.z3_issue_651_remove_bitcoin_seeds, r=ebfull 
Remove Bitcoin mainnet and testnet seeds.

Simple patch for issue #651 to remove hard-coded mainnet and testnet seeds
- they currently point to bitcoin nodes
- some are .onion addresses but Tor support has not yet been added
- gets rid of error messages in debug.log which might confuse people testing the alpha builds

Enforce first four bits are zero for all spending keys and phi.

This introduces a `uint252` to ensure these fields are 252-bits for the PRFs.
