Agree with Udjin on waiting for tests |
We'll need this from another method as well later.
These allow to easily delete multiple chains (actually trees) of ISLOCKs in one go.
…orLock Also add "retryChildren" parameter to RemoveNonLockedTx so that we can skip retrying of non-locked children TXs.
But only when a block is known to have a conflict and at the same time is ChainLocked, which causes the ISLOCK to be pruned.

This PR adds code to handle conflicts between ChainLocks and InstantSend. The probability of such conflicts is practically zero (due to the "safe TXs" concept, as described here), but these should still be handled properly to assure consensus.
This PR lacks tests atm, which I'm working on now. We can either merge this PR first and then later merge the tests, or wait with merging until I'm done with the tests.Update: Added tests
