problem: qt daemon uses significant cpu resources while following the tip. solution: update /depends/ boost library to 1.84 change main.h typedef BlockMap ... mapBlockIndex from std::unordered_map to boost::unordered_map to take advantage of reduced cpu usage during "tip" following. see benchmark info: https://www.boost.org/doc/libs/develop/libs/unordered/doc/html/unordered.html#buckets_benchmarks https://medium.com/@pavel.odintsov/boost-unordered-map-is-a-new-king-of-data-structures-292124d3ee2

problem: qt daemon uses significant cpu resources while following the tip.
solution: update /depends/ boost library to 1.84 to take advantage of new Boost.Unordered improvements
observed improvement on 3.6 ghz Xeon 12 real (24 virtual) core processor
BEFORE: periods of 15 - 30 minutes with 100% of a single virtual core in use, GUI unresponsive for minutes at a time
AFTER: a few seconds of <35-58% cpu utilization occasionally
change main.h
typedef BlockMap ... mapBlockIndex
from std::unordered_map to boost::unordered_map
to take advantage of reduced cpu usage during "tip" following.
