Final reindex algorithm (#1430)
* Mine JSON

* [Reindex tests] add test_params and validate_mining flag to test_consensus

* Rename file and extend tests

* Ignore local test datasets

* Use spaces over tabs

* Reindex algorithm - full algorithm, initial commit, some tests fail

* Reindex algorithm - a few critical fixes

* Reindex algorithm - move reindex struct and all related operations to new file

* Reindex algorithm - added a validateIntervals method and modified tests to use it (instead of exact comparisons)

* Reindex algorithm - modified reindexIntervals to receive the new child as argument and fixed an important related bug

* Reindex attack tests - move logic to helper function and add stretch test

* Reindex algorithm - variable names and some comments

* Reindex algorithm - minor changes

* Reindex algorithm - minor changes 2

* Reindex algorithm - extended stretch test

* Reindex algorithm - small fix to validate function

* Reindex tests - move tests and add DAG files

* go format fixes

* TestParams doc comment

* Reindex tests - exact comparisons are not needed

* Update to version 0.8.6

* Remove TestParams and use AddUTXOInvalidHeader instead

* Use gzipeed test files

* This unintended change somehow slipped in through branch merges

* Rename test

* Move interval increase/decrease methods to reachability interval file

* Addressing a bunch of minor review comments

* Addressed a few more minor review comments

* Make code of offsetSiblingsBefore and offsetSiblingsAfter symmetric

* Optimize reindex logic in cases where reorg occurs + reorg test

* Do not change reindex root too fast (on reorg)

* Some comments

* A few more comments

* Addressing review comments

* Remove TestNoAttackAlternateReorg and assert chain attack

* Minor
