* Merge #13199: Bugfix: ensure consistency of m_failed_blocks after reconsiderblock
11fa6bb66e Bugfix: ensure consistency of m_failed_blocks after reconsiderblock (Suhas Daftuar)
Pull request description:
This was introduced in 015a5258ad and could cause a node to crash (due to assertion failure) when using the `reconsiderblock` rpc.
Tree-SHA512: 820dcd761bf983e36f5d0f16777ed75c833daaf62a6b3a4dbd17f6caaf9287223e3a202d06540ac62f8ba72926b73b0873bb76c6273ddcb19d9408f4c1cd325e
* bugfix: Mark all nearest BLOCK_FAILED_CHILD descendants (if any) as BLOCK_FAILED_VALID while removing the invalidity flag from all ancestors in ResetBlockFailureFlags
Fixes `Assertion failed: ((pindex->nStatus & BLOCK_FAILED_MASK) == 0), function CheckBlockIndex`
* tests: Make sure ResetBlockFailureFlags does the job correctly
* Wait for the expected block height, check the final chain tip hash
