* common, core, eth, les, trie: make prque generic * les/vflux/server: fixed issues in priorityPool * common, core, eth, les, trie: make priority also generic in prque * les/flowcontrol: add test case for priority accumulator overflow * les/flowcontrol: avoid priority value overflow * common/prque: use int priority in some tests No need to convert to int64 when we can just change the type used by the queue. * common/prque: remove comment about int64 range --------- Co-authored-by: Zsolt Felfoldi <zsfelfoldi@gmail.com> Co-authored-by: Felix Lange <fjl@twurst.com>
