Merge #11423: [Policy] Several transaction standardness rules
364bae5 qa: Pad scriptPubKeys to get minimum sized txs (MarcoFalke)
7485488 Policy to reject extremely small transactions (Johnson Lau)
0f8719b Add transaction tests for constant scriptCode (Johnson Lau)
9dabfe4 Add constant scriptCode policy in non-segwit scripts (Johnson Lau)

Pull request description:

  This disables `OP_CODESEPARATOR` in non-segwit scripts (even in an unexecuted branch), and makes a positive `FindAndDelete` result invalid. This ensures that the `scriptCode` serialized in `SignatureHash` is always the same as the script passing to the `EvalScript`.

7384a35849 [tests] Remove spurious error log in p2p_segwit.py
Since 265d7c44b1, when wait_until() fails,
an error message is logged to the test framework log. This means that if
wait_until() is called inside a try-except with the expectation that it
will fail, a spurious error message is logged.

wait_until() shouldn't be called with the expectation of failure. Fix
that in p2p_segwit.py.

Pull request description:

  As discussed at the IRC meeting back in October (https://botbot.me/freenode/bitcoin-core-dev/2017-10-12/?msg=92231929&page=2), I had looked into the feasibility of enforcing P2SH and SCRIPT_VERIFY_WITNESS back to the genesis block.

  The P2SH change is pretty straightforward -- there was only one historical block on mainnet that violated the rule, so I carved out an exception to it, similar to the way we have exceptions for the BIP30 violators.

  The segwit change is not entirely as clear.  The code changes themselves are relatively straightforward: we can just always turn on SCRIPT_VERIFY_WITNESS whenever P2SH is active.  However conceptually, this amounts to splitting up BIP141 into two parts, the part that implements new script rules, and the part that handles witness commitments in blocks.

  Arguably though the script rules are really defined in BIP 143 anyway, and so this really amounts to backdating BIP 143 -- script rules for v0 segwit outputs -- back to genesis.  So maybe conceptually this isn't so bad...

  I don't feel strongly about this change in either direction; I started working on it because I was searching for a way to simplify the way we understand and implement the consensus rules around segwit, but I'm not yet sure whether I think this achieves anything toward that goal.

Pull request description:

  Unfortunately I messed up my repo while trying to squash #12593 so I created a PR with just the correct fixes.

728667b771 scripted-diff: rename TestNode to TestP2PConn in tests
Several test scripts define a subclass of P2PInterface called TestNode.
This commit renames those to TestP2PConn since we already have a
TestNode class in the test framework.
