Previously, there was no way to traverse the trie structure and no way
to identify specific nodes in the trie. That made it impossible to
analyze the trie structure resulting from loading a set of flags. This
change adds type and selector properties to nodes as well as access to
the child nodes of a node to allow for the structure to be analyzed.

Previously, it used a structured string of format <type>:<value>. A
tuple is more efficient and less prone to edge cases, such as when the
value is a field signature which itself contains a ":".

Previously, signature_to_elements would return a string array where
non-wildcard strings were of the form <type>:<value> but wildcard
strings were just * or **. This change makes it handle wildcards
consistently with the other element types and adds some extra
checking for edge cases.

Makes the efficient pattern matching of hidden API flags that is used
by verify_overlaps.py available for use in other scripts.
As part of the move this cleans up the python to use consistent quotes,
and fix pylint issues.
