Merge bitcoin#10695: [qa] Rewrite BIP65/BIP66 functional tests

4ccc12a [qa] Rewrite BIP66 functional tests (Suhas Daftuar)
d4f0d87 [qa] Rewrite BIP65 functional tests (Suhas Daftuar)

Pull request description:

  After 122786d, BIP65 and BIP66 activate at
  particular fixed heights (without regard to version numbers of blocks
  below those heights).  Rewrite the functional tests to take
  this into account, and remove two tests that weren't really testing anything.

  Moves the rewritten functional tests out of the extended test suite, so that they run in travis regularly.

  Note: I discovered that the ComparisonTestFramework (which the original versions of these p2p tests were written is, has a bug that caused them to not catch obvious errors, eg if you just comment out setting the script flags for these softforks in ConnectBlock, the versions of these tests in master do not fail(!) -- will separately PR a fix for the comparison test framework).
