Merge aarzilli/xgb, branch xcb1.12 as nexgb
History has been linearized and rewritten to stay under the new
subdirectory. I want to make changes incompatible to BurntSushi/xgb.
The history begs for being thrown away entirely because of its quality
and because it doesn't cover the Google period but it is still useful
for copyright tracking.
