Bumping `DASH_HASH_VERSION` invalidates docker cache.

NOTE:
[`linux64_tsan-test`](https://gitlab.com/dashpay/dash/-/jobs/4197383660)
failed because tsan build binaries are super slow and we hit 30 minutes
timeout for 1 single test because of that. This is not an actual test
failure.

- Bumped version of `CbTx`. Added fields `bestCLHeightDiff`,
`bestCLSignature`
- Miner starting from v20 fork, includes best CL signature in `CbTx` (if
available) or null signature.
- All nodes should verify included CL signature before accepting the
block.
## How Has This Been Tested?

`feature_llmq_chainlocks.py`

Yes, new version of CbTx

## Issue being fixed or feature implemented
Functional tests in CI and locally often fails without a good reason
(pretty randomly)
## What was done?
It was re-implemented `get_recovered_sig` and updated `create_raw_tx`
for better selection/change output.
## How Has This Been Tested?
Run functional times with bug amount of parrallel jobs:
```
test/functional/test_runner.py -j 20 feature_llmq_is_cl_conflicts.py feature_llmq_is_cl_conflicts.py feature_llmq_is_cl_conflicts.py feature_llmq_is_cl_conflicts.py feature_llmq_is_cl_conflicts.py feature_llmq_is_cl_conflicts.py feature_llmq_is_cl_conflicts.py feature_llmq_is_cl_conflicts.py feature_llmq_is_cl_conflicts.py feature_llmq_is_cl_conflicts.py feature_llmq_is_cl_conflicts.py feature_llmq_is_cl_conflicts.py feature_llmq_is_cl_conflicts.py feature_llmq_is_cl_conflicts.py feature_llmq_is_cl_conflicts.py feature_llmq_is_cl_conflicts.py feature_llmq_is_cl_conflicts.py feature_llmq_is_cl_conflicts.py feature_llmq_is_cl_conflicts.py feature_llmq_is_cl_conflicts.py feature_llmq_is_cl_conflicts.py
```
Without these changes usually 2-3 instance fails.
With these changes all failures happened only for `p2p_addrv2_relay.py`
and `mempool_unbroadcast.py`. Beside feature_llmq_is_conflicts.py
improved stability of `interface_zmq_dash.py` also.

Pull request description:
This hardcodes CSV and segwit activation heights, similar to the BIP 90 buried deployments for BIPs 34, 65 and 66.
CSV and segwit have been active for over 18 months. Hardcoding the activation height is a code simplification, makes it easier to understand segwit activation status, and reduces technical debt.
This was originally attempted by jl2012 in #11398 and again by me in #12360.

faa079db92e614bddfe8bd323ddcd2adb77e0961 travis: Disable feature_block in tsan run (MarcoFalke)
Pull request description:
The `feature_block` test causes the travis machine to OOM, when run with the thread sanitizer.
The stderr says:
```
==27237==ERROR: ThreadSanitizer failed to allocate 0xf6000 (1007616) bytes of LargeMmapAllocator (error code: 12)
...
FATAL: ThreadSanitizer CHECK failed: /build/llvm-toolchain-3.8-_PD09B/llvm-toolchain-3.8-3.8/projects/compiler-rt/lib/sanitizer_common/sanitizer_common.cc:183 "((0 && "unable to mmap")) != (0)" (0x0, 0x0)
ERROR: Failed to mmap
```
(from https://travis-ci.org/bitcoin/bitcoin/jobs/588194563#L10505)
Fix this by disabling `feature_block` on travis. Longer term, I'd like to move away from travis, but I'll leave this for a follow-up.

376f4929f8f75011b72b2f9c3164980db482278a build: disable BIP70 support by default (fanquake)
Pull request description:
Disable BIP70 support in the GUI by default for `0.19.0` (for eventual removal in `0.20.0`?).
Users who want to compile with BIP70 support enabled can pass `--enable-bip70` to `./configure`.
I've inverted the current `--disable-bip70` test to instead pass `--enable-bip70`.
Tested configurations on `macOS` (`protobuf` installed with `brew`).
Protobuf available and `./configure`:
```
Options used to compile and link:
with wallet = yes
with gui / qt = yes
with bip70 = no
```
Protobuf available and `./configure --enable-bip70`:
```
Options used to compile and link:
with wallet = yes
with gui / qt = yes
with bip70 = yes
```
Protobuf not available (i.e `brew unlink protobuf`) and `./configure`:
```
Options used to compile and link:
with wallet = yes
with gui / qt = yes
with bip70 = no
```
Protobuf not available and `./configure --enable-bip70`:
```
checking whether to build test_bitcoin-qt... yes
checking whether to build BIP70 support... configure: error: protobuf missing
```
TODO:
- [x] Remove `protobuf` from other Travis builds
- [ ] Documentation updates (mention that `protobuf` is now optional)?
- [ ] Could split release notes into GUI and build

On master (a6f6333ba253cda83221ee529810cacf930e413f) and on 0.19.0.1 the intro dialog with prune enabled (checkbox "Discard blocks..." is checked) provides a user with wrong info about the required disk space:

Also the paragraph "If you have chosen to limit..." is missed.

With this PR when prune checkbox is toggled, the related text labels and the amount of required space shown are updated (previously they were only updated when the data directory was updated):

Pull request description:
This adds a checkbox to the intro screen to enable pruning from the get go.
If the user has plenty of space, it's unchecked by default:

If the user has insufficient space it's checked by default:
<img width="897" alt="low" src="https://user-images.githubusercontent.com/10217/63641276-d4002f80-c6ab-11e9-9f5b-a53472f814ff.png">
When the user has barely enough space and is likely to need pruning in the near future, this is shown in yellow and we also check the prune box:

The cut-off for this 10 GB above `m_assumed_blockchain_size` (`=240` in `chainparams.cpp`).
If the user launches the first time with `-prune=...` then we disable the check box and display the correct size (rounded to GB):

The 2 GB default matches the settings default. The user can't change it in the intro screen, but can change it later. I'm tempted to increase that default to 10 GB, and then have the intro screen reduce it if space is really tight.
Tips for testing:
* move your existing data dir elsewhere
* wipe data dir at every restart (behavior is different if it exists)
* launch with `bitcoin-qt -resetguisettings -lang=en` (there's some space issues in different languages)
* fake your free space by changing `intro.cpp` line 90: `freeBytesAvailable = 5000000000; // 5 GB`
* try both testnet and mainnet, because settings are seperate. In particular note how step 7 in `GuiMain` switches where `QTSettings settings` points to; this had me thoroughly confused on testnet, because I was setting them too early.

utACK 9924bce317b96ab0c57efb99330abd11b6f16b9a. The changes are very logical, and implement the feature in a clean that way that doesn't add a lot of complication and shouldn't interfere with future improvements. I looked at Luke's branch too, and I think there's also a lot of great stuff there that seems fully compatible with this change.

Pull request description:
Separated from #8994 as suggested by MarcoFalke and Sjors in https://github.com/bitcoin/bitcoin/pull/8994#issuecomment-522555390
You can't really test the qt changes on their own, so to test them, use #8994 .

## Issue being fixed or feature implemented
The benefits of using custom struct `maybe_error` is less significant
since the interface `TxValidationState` became simpler after
refactorings from bitcoin#15921 and bitcoin#17004
The refactoring of `maybe_error` as a class result from PR #5109 is
still useful but not for case of TxValidationState.
## What was done?
Unified using TxValidationState in dash's related code.
## How Has This Been Tested?
Run unit/functional tests
## Breaking Changes
No breaking changes, logic are same.
