TODO: solve memory leak in RewardsCalc (seems in few places we totally
forgot about call `mpz_clear` to clear the memory allocated for each
used variable).

If tests in other translation units leave pblocktree and pcoinsTip
in an initialized state, free the memory and set it to nullptr.

Unlike ZCash, we still have libsnark included in both the
build and dependency systems. Therefore, this commit should
remove all the libsnark-related components from both systems.

The KIP0003 consensus rule was added in the `dev` branch
as "logging only", i.e. as disabled. However, in the
`patch-s8-prepare-hf-test` branch, which we used for
testing on hfnet, it's already enabled
(as seen in [this commit](783fc1f)).
For the release, we should enable this rule and make the
logging optional using the hfnet category.
