Most H2G messages are FAST_REQ which means no synchronous response is
expected. However, errors can still be returned. Add support for
tracking the FAST_REQ H2Gs and matching up an error response to its
originator.
v2: Split RESPONSE define into separate patch, re-word
comments/prints, fix consistency of conditional compilation (review
feedback from Daniele & Michal W).
v3: Split into more patches, add more RESPONSE defines, improve
debug print message (review feedback from Michal W).
v4: Bunch of minor tweaks (more review feedback from Michal W).
