Crucial fix for the UTXO difference mechanism (#2114)
* Illustrate the bug through prints

* Change consensus API to a single ResolveVirtual call

* nil changeset is not expected when err=nil

* Fixes a deep bug in the resolve virtual process

* Be more defensive at resolving virtual when adding a block

* When finally resolved, set virtual parents properly

* Return nil changeset when nothing happened

* Make sure the block at the split point is reversed to new chain as well

* bump to version 0.12.4

* Avoid locking consensus twice in the common case of adding block with updateVirtual=true

* check err

* Parents must be picked first before set as virtual parents

* Keep the flag for tracking virtual state, since tip sorting perf is high with many tips

* Improve and clarify resolve virtual tests

* Addressing minor review comments

* Fixed a bug in the reported virtual changeset, and modified the test to verify it

* Addressing review comments

Fix UTXO diff child error (#2084)
* Avoid creating the chain iterator if high hash is actually low hash

* Always use iterator in nextPruningPointAndCandidateByBlockHash

* Initial failing test

* Minimal failing test + some comments

* go lint

* Add simpler tests with two different errors

* Missed some error checks

* Minor

* A workaround patch for preventing the missing utxo child diff bug

* Make sure we fully resolve virtual

* Move ResolveVirtualWithMaxParam to test consensus

* Mark virtual not updated and loop in batches

* Refactor: remove VirtualChangeSet from functions return values

* Remove workaround comments

* If block has no body, virtual is still considered updated

* Remove special error ErrReverseUTXODiffsUTXODiffChildNotFound
