Test notes:
This test uses the script_valid and script_invalid tests from the unittest
framework to do end-to-end testing where we compare that two nodes agree on
whether blocks containing a given test script are valid.
We generally ignore the script flags associated with each test (since we lack
the precision to test each script using those flags in this framework), but
for tests with SCRIPT_VERIFY_P2SH, we can use a block time after the BIP16
switchover date to try to test with that flag enabled (and for tests without
that flag, we use a block time before the switchover date).
NOTE: This test is very slow and may take more than 40 minutes to run.
