Pull request description:

  At wallet load time, the crypted key "checksum_valid" variable is always set to false. Which, on every wallet decryption call, forces the process to re-write all the ckeys to db when it's not needed.

  Note:
  The first commit fixes the issue, the two commits in the middle are cleanups so `DuplicateMockDatabase`
  can be used without duplicating code. And, the last one is pure test coverage for the crypted keys loading
  process.

  Includes test coverage for the following scenarios:

  1) "All ckeys checksums valid" test:
  Loads an encrypted wallet with all the crypted keys with a valid checksum and
  verifies that 'CWallet::Unlock' doesn't force an entire crypted keys re-write.

      (we force a complete ckeys re-write if we find any missing crypted key checksum
  during the wallet loading process)

  2) "Missing checksum in one ckey" test:
  Verifies that loading up a wallet with, at least one, 'ckey' with no checksum
  triggers a complete re-write of the crypted keys.

  3) "Invalid ckey checksum error" test:
  Verifies that loading up a ckey with an invalid checksum stops the wallet loading
  process with a corruption error.

  4) "Invalid ckey pubkey error" test:
  Verifies that loading up a ckey with an invalid pubkey stops the wallet loading
  process with a corruption error.

Test library

This contains files for the test library, which is used by the test binaries (unit tests, benchmarks, fuzzers, gui tests).

Generally, the files in this folder should be well-separated modules. New code should be added to existing modules or (when in doubt) a new module should be created.

The utilities in here are compiled into a library, which does not hold any state. However, the main file setup_common defines the common test setup for all test binaries. The test binaries will handle the global state when they instantiate the BasicTestingSetup (or one of its derived classes).
