Rebased to Chromium Dev Channel 76.0.3809.12.
The stable channel 75.0.3770.80 is skipped because there has been a major refactor in the socket pool system https://bugs.chromium.org/p/chromium/issues/detail?id=927084, and v75 is in the middle of the refactor series.
Chromium v76 has upgraded from gQUIC to IETF QUIC, which doesn't work with Caddy yet.
A -1 release will be made when Chromium v76 is released as stable version.
