Merge v0.12.3.4 commits into develop (#2582)
* Bump to 0.12.3.3

* Fix crash bug with duplicate inputs within a transaction

Introduced by #9049

* Remove redundant parameter fCheckDuplicateInputs from CheckTransaction

* Release notes 0.12.3.3

* Bump nPowKGWHeight for testnet and cause a fork at height 4001

This will reset testnet so that we can start with a clean state.

* Change CSV, DIP0001 and BIP147 deployments to start today

* Update nMinimumChainWork and defaultAssumeValid for block 4000

* Remove checkpoints above block 4000

* Bump to 0.12.3.4

* Update release-notes.md and copy 0.12.3.3 release-notes

* Don't check for nSuperblockStartHash on testnet

* Remove temporary fork handling for emergency difficulty reduction on testnet

As we reset testnet, we can also remove the special handling for old blocks.

Dash Core version 0.12.3.3
==========================
Release is now available from:
<https://www.dash.org/downloads/#wallets>
This is a critical bugfix release.
Please report bugs using the issue tracker at github:
<https://github.com/dashpay/dash/issues>
Upgrading and downgrading
=========================
How to Upgrade
--------------
If you are running an older version, shut it down. Wait until it has completely
shut down (which might take a few minutes for older versions), then run the
installer (on Windows) or just copy over /Applications/Dash-Qt (on Mac) or
dashd/dash-qt (on Linux).
Downgrade warning
-----------------
### Downgrade to a version < 0.12.2.2
Because release 0.12.2.2 included the [per-UTXO fix](release-notes/dash/release-notes-0.12.2.2.md#per-utxo-fix)
which changed the structure of the internal database, you will have to reindex
the database if you decide to use any pre-0.12.2.2 version.
Wallet forward or backward compatibility was not affected.
### Downgrade to 0.12.2.2/3, 0.12.3.1/2
Downgrading to these versions does not require any additional actions, should be
fully compatible.
Notable changes
