@laanwj Yes, nice change. I've added that here. Edit: Added as a new commit to preserve the previous ACKs. Will squash when you're ready. |

The PRs are as follows: - bitcoin#9037 - net: Add test-before-evict discipline to addrman - bitcoin#5151 - make CMessageHeader a dumb storage class - bitcoin#6589 - log bytes recv/sent per command - bitcoin#8688 - Move static global randomizer seeds into CConnman - bitcoin#9050 - net: make a few values immutable, and use deterministic randomness for the localnonce - bitcoin#8708 - net: have CConnman handle message sending - bitcoin#9128 - net: Decouple CConnman and message serialization - bitcoin#8822 - net: Consistent checksum handling - bitcoin#9441 - Net: Massive speedup. Net locks overhaul - bitcoin#9609 - net: fix remaining net assertions - bitcoin#9626 - Clean up a few CConnman cs_vNodes/CNode things - bitcoin#9698 - net: fix socket close race - bitcoin#9708 - Clean up all known races/platform-specific UB at the time PR was opened - Excluded bitcoin/bitcoin@512731b and bitcoin/bitcoin@d8f2b8a, to be done in a separate PR ACKs for top commit: furszy: code ACK 30d5c66 , testnet sync from scratch went well and tested with #1829 on top as well and all good. furszy: mainnet sync went fine, ACK 30d5c66 . random-zebra: ACK 30d5c66 and merging...

It shouldn't know or care about bitcoind's chain param selection. MessageStartChars is changed to be passed into CMessageHeader's ctor rather than having it pulled from the current app state.
This isn't necessary for the current consensus lib work, but PR'ing now anyway since it's pretty straightforward and non-intrusive. Fine to wait until post-0.10 if preferred.
