  6. Add a switch to allow running in a pruned state. 

    These are the main functional changes on this state:

* Do not allow running with a wallet or txindex.
* Check for data at startup is mandatory only up to the last 288 blocks.
* NODE_NETWORK flag is unset.
* Requests for pruned blocks from other peers is answered with "notfound" and they are disconnected, not to stall their IBD.

  9. Simplify CheckBlockFiles routine. 

    We can do it now that the logic to avoid opening the files several times has been
moved to their own functions and is handled mainly through variables.
