dac7a111bdd3b0233d94cf68dae7a8bfc6ac9c64 refactor: test: use _ variable for unused loop counters (Sebastian Falbesoner)
Pull request description:
This tiny PR substitutes Python loops in the form of `for x in range(N): ...` by `for _ in range(N): ...` where applicable. The idea is indicating to the reader that a block (or statement, in list comprehensions) is just repeated N times, and that the loop counter is not used in the body, hence using the throwaway variable. This is already done quite often in the current tests (see e.g. `$ git grep "for _ in range("`). Another alternative would be using `itertools.repeat` (according to Python core developer Raymond Hettinger it's [even faster](https://twitter.com/raymondh/status/1144527183341375488)), but that doesn't seem to be widespread in use and I'm not sure about a readability increase.
The only drawback I see is that whenever one wants to debug loop iterations, one would need to introduce a loop variable again. Reviewing this is basically a no-brainer, since tests would fail immediately if a a substitution has taken place on a loop where the variable is used.
Instances to replace were found by `$ git grep "for.*in range("` and manually checked.

ACK dac7a111bdd3b0233d94cf68dae7a8bfc6ac9c64 -- the updated code is easier to reason about since the throwaway nature of a variable is expressed explicitly (using the Pythonic `_` idiom) instead of implicitly. Explicit is better than implicit was we all know by now :)

## Issue being fixed or feature implemented
Be more explicit about the fact that spork24 is for non-mainnet only,
enforce it in code.
NOTE: I know we have EHF signalling disabled for mainnet in v20 but I
think it still makes sense to make sure spork24 condition won't slip
into mainnet in some future version accidentally.

`Params()` should be const; global variable `CMNHFManager` is a better
out-come.
## What was done?
The helpers and direct calls of `UpdateMNParams` for each block to
update non-constant member in `Params()` is not needed anymore. Instead
`CMNHFManager` takes cares about status of Signals for each block,
update them dynamically and save in evo db.
## How Has This Been Tested?
Run unit/functional tests.
## Breaking Changes
Changed rpc `getblockchaininfo`.
the field `ehf` changed meaning: it's now only a flag -1/0; but it is
introduced a new field `ehf_height` now that a height.

Implementation EHF mechanism, part 4. Previous changes are:

- https://github.com/dashpay/dash/pull/5505
- https://github.com/dashpay/dash/pull/5469
## Issue being fixed or feature implemented
Currently MN_RR is activated automatically by soft-fork activation after
v20 is activated.
It is not flexible enough, because platform may not be released by that
time yet or in opposite it can be too long to wait.
Also, any signal of EHF requires manual actions from MN owners to sign
EHF signal - it is automated here.
## What was done?
New spork `SPORK_24_MN_RR_READY`; new EHF manager that sign EHF signals
semi-automatically without manual actions; and send transaction with EHF
signal when signal is signed to network.
Updated rpc `getblockchaininfo` to return information about of EHF
activated forks.
Fixed function `IsTxSafeForMining` in chainlock's handler to skip
transactions without inputs (empty `vin`).
## How Has This Been Tested?
Run unit/functional tests. Some tests have been updated due to new way
of MN_RR activation: `feature_asset_locks.py`, `feature_mnehf.py`,
`feature_llmq_evo.py` and unit test `block_reward_reallocation_tests`.
## Breaking Changes
New way of MN_RR activation.
