The checks from the new clang-tidy file are applied to the source tree
using:
$ find . -name "*.cpp" | sort -u | xargs \
--max-procs 8 --max-args 1 clang-tidy --format-style=file \
--fix -p /path/to/compile_commands.json

This commit adds a unit test for the USE_MAP property forwarding policy.
It also adds a pair of new mock RFNoC nodes for use in unit testing:
- mock_edge_node_t is a node with a configurable number of input and
output ports each having an edge property named 'prop' associated with
each. The node is also able to source actions from any of its edges and
records incoming actions in a map.
- mock_routing_node_t is a do-nothing node specifically for testing
property and action forwarding between edges with the USE_MAP forwarding
strategy. The node has functions to configure the property and action
forwarding maps.

This introduces the concept of a resolution context, because the
property propagation algorithm needs to behave differently when called
during an initialization step (e.g. when the graph is committed), or
when the user changes a property on one of the nodes after it was
committed.
The algorithm is modified as follows:
- When called during an initialization step, then all nodes get resolved
at least once. If nodes added new properties, then all nodes get
touched again until the max number of iterations is reached.
- When called because a node modified one of its properties, then that
node is always resolved first. From there, all other nodes are
resolved in topological order. However, the algorithm immediately
terminates as soon as there are no more dirty nodes.
- When called because a node modified one of its properties, but the
graph is currently not in a committed state, then that node will do
a local property resolution.

When a node has multiple properties that depend on each other (and
possible have circular dependencies), the previous version of property
propagation would not correctly resolve properties that got flagged
dirty during the execution of other resolvers.

- Adds a detail::graph_t class, which handles the propagation
- Adds methods to node_t to aid with propagation
- Adds unit tests
- Adds dynamic property forwarding:
Nodes are now able to forward properties they don't know about by
providing a forwarding policy. A good example is the FIFO block which
simply forwards most properties verbatim.
