Zcash: Makes future extensions easier.
Original description (when this was introduced upstream):
Pass parent wrapper directly instead of obfuscation key. This
makes it possible for other databases which re-use this code
to use other properties from the database.
Add a namespace dbwrapper_private for private functions to be used
only in dbwrapper.h/cpp and dbwrapper_tests.
If a block is insufficiently-validated against a particular branch ID, then we
cannot guarantee that even the block header will be valid under the actual
consensus rules the node will want to apply. Instead require that the blocks are
completely re-validated, by removing them from the block index (which is
equivalent to reducing their validity to BLOCK_VALID_UNKNOWN).
The Equihash check caused block index loading to take around 38x longer.
However, we don't need to check it directly, as the only paths to writing a
block header to disk already go through a proof-of-work check (e.g. receiving a
block over the network). By forcing the block header inside the CBlockIndex to
be re-serialized, we retain the benefits of the consistency check without the
overhead at startup.

Check Equihash solution when loading block index
An additional consistency check, which also ensures that the in-memory representation
matches the stored index.
read hashReserved from disk
This fixes a bug where the hashReserved field of the block header is not properly read back into CBlockIndex when loaded from disk. This happens to cause no issues currently because hashReserved has always been its default value (== 0), but if a block were ever mined where this was not the case, headers read back from disk would appear to have an invalid solution
