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.

+	Tests for XGB.
+
+	These tests only test the core X protocol at the moment. It isn't even
+	close to complete coverage (and probably never will be), but it does test
+	a number of different corners: requests with no replies, requests without
+	replies, checked (i.e., synchronous) errors, unchecked (i.e., asynchronous)
+	errors, and sequence number wrapping.
+
+	There are also a couple of benchmarks that show the difference between
+	correctly issuing lots of requests and gathering replies and
+	incorrectly doing the same. (This particular difference is one of the
+	claimed advantages of the XCB, and therefore XGB, family.)
+
+	In sum, these tests are more focused on testing the core xgb package itself,
+	rather than whether xproto has properly implemented the core X client
+	protocol.
