…tests (speed, prevent timeout)

12f094e test: use constants for CSV/CLTV activation heights in rpc_signrawtransaction (Sebastian Falbesoner)
746f203 test: introduce `generate_to_height` helper, use in rpc_signrawtransaction (Sebastian Falbesoner)
e3237b1 test: check that CSV/CLTV are active in rpc_signrawtransaction (Sebastian Falbesoner)

Pull request description:

  This PR primarily aims to solve the current RPC timeout problem for test rpc_signrawtransaction.py, as described in bitcoin#22542. In the course of that the test is also improved in other ways (see bitcoin#22542 (review)).

  Reviewers guideline:
  * In `test_signing_with_cltv()`, a comment is fixed -- it wrongly referred to CSV, it should be CLTV.
  * As preparation, assertions are added that ensure that CSV and CLTV have been really activated after generating blocks by checking the 'softforks' output of the getblockchaininfo() RPC. Right now in master, one could remove (or decrease, like in bitcoin#22542) the generate calls and the test would still pass, when it shouldn't.
  * A helper `generate_to_height()` is introduced which improves the previous way of reaching a block height in two ways:
      - instead of blindly generating TH blocks to reach target block height >= TH, the current block height CH is taken into account, and only (TH - CH) are generated in total
      - to avoid potential RPC timeouts, the block generation is split up into multiple generatetoaddress RPC calls ([as suggested by laanwj](bitcoin#22542 (comment))); here chunks of 200 blocks have been chosen
   * The helper is used in the affected sub-tests, which should both speed-up the test (from ~18s to ~12s on my machine) and avoid potential timeouts
   * Finally, the activation constants for CSV and CLTV are used instead of using magic numbers 500 and 1500

  Open questions:
  * Any good naming alternatives for `generate_to_height()`? Not really happy with the name, happy to hear suggestions
  * Where to put the CSV and CLTV activation height constants in the test_framewor folder? I guess importing constants from other tests isn't really the desired way to go

… to avoid gcc warning

0591710 consensus/params: simplify ValidDeployment check to avoid gcc warning (Anthony Towns)

Pull request description:

  Simplifies the ValidDeployment check to only check the upperbound, relying on the lower bound to be trivially true due to enum values starting at the minimum value of the underlying type (which is checked at compile time in deploymentstatus.cpp). Avoids a "comparison always true" warning in some versions of gcc.

  Fixes bitcoin#22587

fafe896 test: Set regtest.BIP66Height = 102 to speed up tests (MarcoFalke)

Pull request description:

  No need to waste time by forcing creation of more than 1000 blocks to get the benefits of being able to test BIP 66. Also, reducing the height makes it more likely that (third-party) tests are conforming to BIP 66, which is enforced on mainnet for all new blocks.

fa676db test: pep-8 whitespace (MarcoFalke)
faed284 test: Avoid intermittent test failure in feature_csv_activation.py (MarcoFalke)

Pull request description:

  Otherwise there will be disconnects if the test runs longer than the default peertimeout (60s):

  ```
   node0 2021-09-05T20:28:30.973116Z (mocktime: 2021-09-01T07:17:29Z) [net] [net.cpp:1323] [InactivityCheck] socket receive timeout: 393061s peer=0
  ```

  Fix that by skipping `InactivityCheck` via a large `-peertimeout`.

222290f test: Set BIP34Height = 2 for regtest (MarcoFalke)
fac90c5 test: Create all blocks with version 4 or higher (MarcoFalke)

Pull request description:

  BIP34 is active on the current tip of mainnet, so all miners must obey it. It would be nice if it also was active in fresh regtest instances from the earliest time possible.

  I changed the BIP34 height to `2`, so that the block at height=1 may be used to mine a duplicate coinbase. (Needed to test mainnet behaviour)

  This pull is done in two commits:

  *  test: Create all blocks with version 4 or higher:
     Now that BIP34 is activated earlier, we need to create blocks with a higher version number. Just bump it to 4 instead of 2 to avoid having to bump it again later.

  *  test: Set BIP34Height = 2 for regtest:
     This fixes the BIP34 implementation in the tests (to match the one of the Core codebase) and updates the tests where needed
