util: enhance `nullcontextmanager` to be able to return __enter__ result

This makes its functionality and signature equivalent to Python 3.7’s
contextlib.nullcontext().

Tests for wire protocol version 2 exchange.
Tests in this file should be folded into existing tests once protocol
v2 has enough features that it can be enabled via #testcase in existing
tests.
