Summary

Since Antminer S9s now are able to do overt asicboost, there are many unknown
versions on mainnet headers. This is triggering warnings in the debug.log and it
is not apparent that this is meaningful any longer. Additionally, the BIP9 code
has been removed for activating any softforks based on the version bits anyways.

Depends on D3381

Depends on itself?

This revision now requires changes to proceed.Jun 21 2019, 22:06

Note backports are basically caught up on this part of the code, except weak overlap with the incomplete parts of D1972, and some linting-related stuff in #12891 (which it looks like will we cannot take as-is due to code style differences).

This revision is now accepted and ready to land.Jun 24 2019, 18:32
