Notable changes

Optimize release build

The release build now sets CLAGS/CXXFLAGS to use the -O3 optimization option, which turns on more optimization flags than the previously used -O1. This produces a faster build, addressing a performance regression in v4.1.0.

Correctly report Founders' Reward amount in getblocktemplate

This release correctly returns the foundersreward field from getblocktemplate output pre-Canopy and removes the field post-Canopy. (The Founders' Reward will expire exactly as Canopy activates, as specified in ZIP 207.) To obtain information about funding stream amounts, use getblocksubsidy HEIGHT, passing in the height returned by the getblocktemplate API.
