utACK dd8654b

Running now to compare coverage before and after this patch. I like that the fuzzers now have SendMessages coverage.

Coverage from dd8654b:
https://crypt-iq.github.io/20370_review/covrun1/src/net_processing.cpp.gcov.html

Compared to a recent master commit (should have recorded this...oh well):
https://crypt-iq.github.io/20370_review/covrun_master/src/net_processing.cpp.gcov.html

Coverage goes up because of SendMessages, but ProcessMessage coverage is worse. I think it's probably due to the seed change.
