Separates the act of creating a TestNode object from starting the node.
The test_framework now keeps track of its list of TestNodes, and test
writers can call start_node() and stop_node() without having to update
the self.nodes list.

sync_with_ping currently returns false if the timeout expires, and it is
the caller's responsibility to fail the test. However, none of the tests
currently assert on sync_with_ping()'s return code. This commit adds an
assert to sync_with_ping so the test will fail if the timeout expires.
This commit also removes all the duplicate implementations of
sync_with_ping() from the individual tests.
This commit merges the NodeConnCB and SingleNodeConnCB into a single
class (called NodeConnCB). The original intent for the NodeConnCB was to
be able to have a python 'mininode' connect to multiple running
bitcoinds. This has never been used and can be achieved more easily by
having multiple NodeConns backed by a common datastore if it is ever
needed.
The changes in mininode.py are just code moves (and merging the two
classes into a single class). The code changes in the individual test
cases are changing the subclasses to subclass from NodeConnCB instead of
SingleNodeConnCB. There is a lot of duplicate code in the subclasses
that can be removed in future commits.
assumevalid was merged as part of PR 9484, but was not added to the
test_runner, so is not run even as part of the extended tests.
This commit adds assumevalid to the list of tests in test_runner. It
also clarifies the code in assumevalid considerably.
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.
Adds a qa testcase testing the new "-assumevalid" option. The testcase builds
a chain that includes and invalid signature for one of the transactions and
sends that chain to three nodes:
- node0 has no -assumevalid parameter and rejects the invalid chain.
- node1 has -assumevalid set and accepts the invalid chain.
- node2 has -assumevalid set but the invalid block is not buried deep
enough to assume invalid, and so rejects the invalid chain.
