  There currently exist seven ([1](https://github.com/bitcoin/bitcoin/blob/master/test/functional/feature_cltv.py#L52-L60), [2](https://github.com/bitcoin/bitcoin/blob/master/test/functional/feature_csv_activation.py#L88-L95) [3](https://github.com/bitcoin/bitcoin/blob/master/test/functional/feature_dersig.py#L40-L48), [4](https://github.com/bitcoin/bitcoin/blob/master/test/functional/feature_nulldummy.py#L100-L108), [5](https://github.com/bitcoin/bitcoin/blob/master/test/functional/test_framework/util.py#L529-L535), [6](https://github.com/bitcoin/bitcoin/blob/master/test/functional/test_framework/blocktools.py#L120-L129), [7](https://github.com/bitcoin/bitcoin/blob/master/test/functional/feature_block.py#L1218-L1220)) implementations of a function called something similar to `create_transaction` in the functional tests, some of which are exact copies of each other.

  This PR aims to clean this up into [three different cases implemented in blocktools.py](https://github.com/conscott/bitcoin/blob/create_tx_cleanup/test/functional/test_framework/blocktools.py#L121-L149)
  1. `create_tx_with_script`: Return transaction object spending generic tx output optionally specifying scriptSig and scriptPubKey
  2. `create_transaction`: Return transaction object spending coinbase tx
  2. `create_raw_transaction`: Return raw transaction (hex string) spending coinbase tx

  I am not committed to any of these function names, so I'll gladly take suggestions on there.

  Additionally there are some related cleanups to feature_block.py tests, specifically removing the [PreviousSpendableOutput](https://github.com/conscott/bitcoin/blob/master/test/functional/feature_block.py#L51-L54) object, which seems like an unnecessary layer given that every instance spends the 0 output.
