Wladimir J. van der Laan c0902624b0 Merge #10699 : Make all script validation flags backward compatible

01013f5 Simplify tx validation tests (Pieter Wuille)
2dd6f80 Add a test that all flags are softforks (Pieter Wuille)
2851b77 Make all script verification flags softforks (Pieter Wuille)

Pull request description:

  This change makes `SCRIPT_VERIFY_UPGRADABLE_NOPS` not apply to `OP_CHECKLOCKTIMEVERIFY` and `OP_CHECKSEQUENCEVERIFY`. This is a no-op as `UPGRADABLE_NOPS` is only set for mempool transactions, and those always have `SCRIPT_VERIFY_CHECKLOCKTIMEVERIFY` and `SCRIPT_VERIFY_CHECKSEQUENCEVERIFY` set as well. The advantage is that setting more flags now always results in a reduction in acceptable scripts (=softfork).

  This results in a nice and testable property for validation, for which a new test is added.

  This also means that the introduction of a new definition for a NOP or witness version will likely need the following procedure (example OP_NOP8 here)
  * Remove OP_NOP8 from being affected by `SCRIPT_VERIFY_DISCOURAGE_UPGRADABLE_NOPS`.
  * Add a `SCRIPT_VERIFY_DISCOURAGE_NOP8`, which only applies to `OP_NOP8`.
  * Add a `SCRIPT_VERIFY_NOP8` which implements the new consensus logic.
  * Before activation, add `SCRIPT_VERIFY_DISCOURAGE_NOP8` to the mempool flags.
  * After activation, add `SCRIPT_VERIFY_NOP8` to both the mempool and consensus flags.
