Merge #13431: validation: count blocks correctly for check level < 3
f618ebc4e4 validation: count blocks correctly for check level < 3 (Karl-Johan Alm) Pull request description: As noted in https://github.com/bitcoin/bitcoin/pull/13428#issuecomment-396129295 there is a bug where if check level < 3, the resulting count for blocks is wrong, because `pindexState` is never updated. Post-commit `./bitcoin-cli verifychain 1 3`: ``` 2018-06-11T07:12:28Z Verifying last 3 blocks at level 1 2018-06-11T07:12:28Z [0%]...[33%]...[66%]...[99%]...[DONE]. 2018-06-11T07:12:28Z No coin database inconsistencies in last 3 blocks (0 transactions) ``` Pre-commit `./bitcoin-cli verifychain 1 3`: ``` 2018-06-11T07:13:34Z Verifying last 3 blocks at level 1 2018-06-11T07:13:34Z [0%]...[33%]...[66%]...[99%]...[DONE]. 2018-06-11T07:13:34Z No coin database inconsistencies in last 0 blocks (0 transactions) ``` Tree-SHA512: 3d82ed26665162c9615fb0e6e91a46ed4d229a5e6797c6c420e6b0bf1be6e5e02401c6e9a93b7a5aec503a2650d8c20d1b45fe300a922379e4cef8ee26e18d96
