Almost all test scripts currently need to override the __init__()
method. When they do that they need to call into super().__init__() as
the base class does some generic initialization.
This commit makes the base class __init__() call into set_test_params()
method. Individual test cases can override set_test_params() to setup
their test parameters.
This commit fixes the module-level docstrings for the tests and helper
modules in qa. Many of these tests were uncommented previously - this
commit ensures that every test case has at least a minimum level of
commenting.
Port over https://github.com/chronokings/huntercoin/pull/19 from
Huntercoin: This implements a new RPC command "getchaintips" that can be
used to find all currently active chain heads. This is similar to the
-printblocktree startup option, but it can be used without restarting
just via the RPC interface on a running daemon.
