This deals with the `feature_*.py`, `interface_*.py` and `mining_*.py` tests.

"""Test loadblock option
|

|
|
Test the option to start a node with the option loadblock which loads

a serialized blockchain from a file (usually called bootstrap.dat).
|

To generate that file this test uses the helper scripts available

in contrib/linearize.
