instead of block.nTime (pblock->nTime). This should prevent existance of
txes, which are already added in mempool, but never will be added to a
block (skipped on create blocktemplate stage), bcz of MTP too far away
from block creation time in case of big gaps between blocks.

… error

Before debug.log in case of komodo_validate_interest failed was like:

2022-04-29 03:14:33 AcceptToMemoryPool komodo_validate_interest failure
2022-04-29 03:14:33 ERROR: AcceptToMemoryPool: komodo_validate_interest failed

We removed 1st message and added txid to 2nd.

# Conflicts:
#	src/main.cpp

We don't need to call pindexPrev->GetMedianTimePast() on every mempool
tx iteration, it's calculated before in nMedianTimePast. Also we don't
need params variable, as we already have consensusParams defined above.

- re-format, remove useless comments and dead code.
- remove unused variables.
- remove set<CBitcoinAddress> setAddress and conditions containing
  it, bcz setAddress.size() is always 0, so these paths in the code
  are dead.
- get rid of most pointer operations, instead of memcmp passed notarypub33,
  we construct targetP2PKScript and compare it with scripts from
  available utxos.
- don't allow to spend unconfirmed 10k sat. utxos, bcz we don't ensure that they would be included in the same block.

to pass two params in a function earlier we used a (void **) to
handle pointers on these 2 params in "array". also there was "hidden"
parameter, this pointer itself, if pointer == 0 -> it before HF time,
if pointer !=0 -> after HF time, and we should extract two params from
array of passed pointers. of course it can be replaced with tuple, or
boost::optional with tuple "inside", but much more simple way is to
pass params (CScript and nLockTime) in komodo_notaryvin same way as they
exits and assume that if passed CScript().size() == 0, it before HF
and if size() > 0 - it after HF.
