Summary

Discovered while debugging parked chain behavior. I noticed the BlockStatus had unexpected combinations of state. With a chain A->B->C (tip):

parkblock(blockB) produces: A (no state change) -> B (parked, parked-parent) -> C (parked-parent)
Expected is: A (no state change) -> B (parked) -> C (parked-parent)

invalidateblock(blockB) produces: A (no state change) -> B (invalid, invalid-parent) -> C (invalid-parent)
Expected is: A (no state change) -> B (invalid) -> C (invalid-parent)

jasonbcox added a child revision: D1977: Merge #11531: Check that new headers are not a descendant of an invalid block (more effeciently).Nov 1 2018, 18:48

This change is actually incorporated into this backport: D1977, so is unnecessary as long as that change gets in soon.

Then again, I don't think it's a good assumption to think D1977 will go through a quick review. This fix may be necessary in the short term.
