* Unify autoIS/send_smth functions
* Rename autoix-mempool.py -> autois-mempool.py
* Make sure create_raw_trx produces expected results
* Make sure sender has enough inputs and nodes are synced before starting the actual test
* Mine one block to clean mempool up
* 2 blocks is enough for IS on regtest
This also unifies it across different IS tests
* Allow wait_for_instantlock to be called on any node, not only on the one that has the tx in the wallet
* No need to query for tx this often in wait_for_instantlock
* Rename create_raw_trx -> create_raw_tx
* Fund sender with a single TX instead of 30
* Require only 3 out of 5 signatures for old InstantSend in regtest mode
* Use LLMQs of size 5 with threshold of 3 for regtest
* Fix wrong check for out-of-range bits in CFixedBitSet
* Reduce number of masternodes in masternode/LLMQ tests
* Add missing \n to LogPrintf call
* Use correct indexes for isolated/receiver/sender nodes
The way it was before resulted in nodes 1-3 being unused and 6-8 being used
for these 3 special nodes even though these are masternodes.
* Avoid stopping/starting isolated node in p2p-instantsend.py
It's enough to disable networking for this node.
* Fix remaining `print`s in tests
* use AssertLockHeld(cs) instead of relying on comments
* actually use `clsig` in `EnforceBestChainLock()`
* fix log output in `EnforceBestChainLock()`
* drop comments
* Implement copy_datadir to allow easy copying of state from one node to another
* Instead of starting with a fresh datadir for MNs, reuse a copy of the faucet
* Start masternodes in parallel instead of waiting for the previous to finish
* Allow specifying of window and threshold with -bip9params
* Implement -dip3activationheight for regtests
* Implement fast DIP3 activation in DashTestFramework
* Speed up activation of DIP3 in dip3-deterministicmns.py
* Update qa/rpc-tests/test_framework/test_framework.py

* Always assign fast_dip3_activation
* create base class for dash-specific tests
* use common base class in p2p-autoinstantsend.py
* use common base class in p2p-instantsend.py
* rename check_IX_lock to wait_for_instantlock
* fix issue with trx amounts precision in autoix-mempool.py
* fix issue with trx amounts precision in p2p-autoinstantsend.py
* fix issue with trx amounts precision in p2p-instantsend.py
* Rallback adding empty line
* Rallback adding empty line
