Pull request description:

  Current backports for *0.21.1*.

  One conflict was in the test case.

ACKs for top commit:
  ajtowns:
    ACK 5a2d98c640cf308d3c7e85ba51fbb7e84f99322a -- checked 'rebased-from' patches are in master, and rebased patches are clean rebases (except for the first one which changes `""s` to `std::string("")` to avoid c++17 dependency). commits seem fine, but haven't reviewed in detail.
  fanquake:
    ACK 5a2d98c640cf308d3c7e85ba51fbb7e84f99322a - branched off `0.21` and redid the backports. Minor conflict in c33fbab25c82b6a18773b80e8b355c987066ae5a. The diff between my branch and #20901 was just in release notes, `_CLIENT_VERSION_RC` (#20901 branched before 95ea54ba089610019a74c1176a2c7c0dba144b1c) and #21490 which has already been merged into `0.21`.

Tree-SHA512: 75d16d3cf9066a45759758b8185dc3b9dad6a6102c2ac9921f758a310e48d5d3122f0dafa515df42475235fc66a42cc04dd156ee1e61c86a1238bd11707642ea
