Teach RPC interface about dpow-enabled minconfs (#1231)

* Make minconfs dpow-aware in z_listunspent + z_listreceivedbyaddress

* Add dpow-related test files to test suite

* Add dpow simulation to regtest every 7 blocks

* Fix compiler errors

* Fix link error

* Fix stdout spam when running regtests

* Dpowminconfs for listreceivedbyaddress

* dpowconfs tests

* Start adding specific tests for dpowminconfs in listreceivedbyaddress

* Get dpowminconfs tests for listreceivedbyaddress working

* Add dpowminconfs to getreceivedbyaddress + listunspent

* Add test for listtransactions + getreceivedbyaddress support

* Reliably passing dpowminconf tests. We only check for notarized-ness now, not exact confirmation numbers, to avoid race conditions

* Poll for the expected notarization info before running further tests; add support for getbalance

* Migrate tx_height() to a place where asyncrpcoperation_sendmany.cpp can use it

* fix

* Teach GetFilteredNotes about dpowconfs

Many RPCs rely on this internal function, which now correctly uses
dpowconfs to filter by the minconf/maxconf parameters.

* Fix sendmany when using non-default minconf

* inline seems to make things happy

* cleanup

* Add some code to test z_sendmany, which points out https://github.com/jl777/komodo/issues/1247

* try this

* Use already calculated value of dpowconfs instead of calculating it again
