* Prune block and undo files (blk???.dat and undo???.dat) so that the disk space used is less than a user-defined target.

* space is allocated in a block or undo file, staying below the target. Changing back to unpruned requires a reindex
* (which in this case means the blockchain must be re-downloaded.)
*
* Pruning functions are called from FlushStateToDisk when the global fCheckForPruning flag has been set.
* Block and undo files are deleted in lock-step (when blk00003.dat is deleted, so is rev00003.dat.)
* Pruning cannot take place until the longest chain is at least a certain length (100000 on mainnet, 1000 on testnet, 1000 on regtest).
* Pruning will never delete a block within a defined distance (currently 288) from the active chain's tip.
* The block index is updated by unsetting HAVE_DATA and HAVE_UNDO for any blocks that were stored in the deleted files.
* A db flag records the fact that at least some block files have been pruned.
