New RPCs

• Add getquorumproofchain and verifyquorumproofchain for compact mining-transaction proofs from an independently trusted snapshot, plus getchainlockbyheight for historical coinbase-carried certificates. The RPCs read required blocks on demand, without an additional index or startup scan, and keep what they read in bounded in-memory caches of up to about 50 MiB. Nodes must retain the required historical blocks to generate proofs. (#7107, #7727)
