Module QualifiedCppName.Match

Module to match qualified C++ procnames "fuzzily", that is up to namescapes and templating. In particular, this deals with the following issues:

1. 'std::' namespace may have inline namespace afterwards: std::move becomes std::__1::move. This happens on libc++ and to some extent on libstdc++. To work around this problem, make matching against 'std::' more fuzzier: std::X::Y::Z will match std::.*::X::Y::Z (but only for the 'std' namespace).

1. The names are allowed not to commit to a template specialization: we want std::move to match std::__1::move<const X&> and std::__1::move<int>. To do so, comparison function for qualifiers will ignore template specializations.

For example:

"std", "move":

• matches: "std", "blah", "move"
• matches: "std", "blah<int>", "move"
• does not match: "std","blah", "move", "BAD" - we don't want std::.*::X::.* to pass
• does not match: "stdBAD", "move", - it's not std namespace anymore

"folly", "someFunction"

• matches: "folly","someFunction"
• matches: "folly","someFunction<int>"
• matches: "folly<int>","someFunction"
• does not match: "folly", "BAD", "someFunction" - unlike 'std' any other namespace needs all qualifiers to match
• does not match: "folly","someFunction<int>", "BAD" - same as previous example
