zkbot d0cc00207b Auto merge of #929 - bitcartel:zc.v0.11.2.z2_fix_717, r=ebfull 
Fix issue #717 t

Fix issue #717 where if addrman is starved of addresses (e.g. on testnet)
the Select_() function will loop endlessly trying to find an address,
and therefore eat up 100% cpu time on the 'opencon' thread.

Solution is to (1) add a delay to the loop and (2) restrict the number
of attempts to find an address.  On exiting the loop, we return
to an outer loop in net.cpp which will sleep, add seed nodes and
calculate new addresses.

Simon edab3ddd2e Implement issue #997 to reduce time for test_bitcoin due to sleeps in 
addrman.  Related to issue #717.

zkbot 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.

zkbot 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
