Trigger -alertnotify if network is upgrading without you
This adds a -regetest-only undocumented (for regression testing only) command-line option -blockversion=N to set block.nVersion. Adds to the "has the rest of the network upgraded to a block.nVersion we don't understand" code so it calls -alertnotify when 51 of the last 100 blocks are up-version. But it only alerts once, not with every subsequent new, upversion block. And adds a forknotify.py regression test to make sure it works. Tested using forknotify.py: Before adding CAlert::Notify, get: Assertion failed: -alertnotify did not warn of up-version blocks Before adding code to only alert once: Assertion failed: -alertnotify excessive warning of up-version blocks After final code in this pull: Tests successful
