Instead of iterating over 0 .. 1 and then deciding on an actual desired
value, use a range based for loop for the desired value.

Use of `sprintf` is seen as a red flag as many of its uses are insecure.
OpenBSD warns about it while compiling, and some modern platforms, e.g.
[cloudlibc from cloudabi](https://github.com/NuxiNL/cloudlibc) don't
even provide it anymore.
Although our uses of these functions are secure, it can't hurt to
replace them anyway. There are only 3 occurences left, all in the
tests.
I made a silly mistake in a database wrapper where keys
were sorted by char instead of uint8_t. As x86 char is signed
the sorting for the block index database was messed up, resulting
in a segfault due to missing records.
Add a test to catch:
- Wrong sorting
- Seeking errors
- Iteration result not complete
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.
When rewinding, remove insufficiently-validated blocks
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).
Closes#3100.

Return JoinSplit and JoinSplitOutput indexes in z_listreceivedbyaddress
This implements a feature request by @nathan-at-least in https://github.com/zcash/zcash/issues/2932 and I wanted to ask for feedback about the exact form of the data returned before updating tests and docs.
Add Note Locking to z_mergetoaddress
Adds note locking to `z_mergetoaddress` allowing it to be invoked multiple times before previous `z_mergetoaddress` operations have finished.

Make Rust compilation mandatory
The temporary integration check in CheckEquihashSolution() remains, until we
have "real" Rust code to integrate.
Closes#2688.
Ignore -mempooltxinputlimit once Overwinter activates
Overwinter changes the SignatureHash function to solve the quadratic hashing problem, so this option will no longer be needed.
