 """Compute global interface information, including public information, dependencies, and inheritance.

 Computed data is stored in a global variable, |interfaces_info|, and written as
 output (concretely, exported as a pickle). This is then used by the IDL compiler
 itself, so it does not need to compute global information itself, and so that
 inter-IDL dependencies are clear, since they are all computed here.

 The |interfaces_info| pickle is a *global* dependency: any changes cause a full
 rebuild. This is to avoid having to compute which public data is visible by
 which IDL files on a file-by-file basis, which is very complex for little
 benefit.
 |interfaces_info| should thus only contain data about an interface that
 contains paths or is needed by *other* interfaces, e.g., path data (to abstract
 the compiler from OS-specific file paths) or public data (to avoid having to
 read other interfaces unnecessarily).
 It should *not* contain full information about an interface (e.g., all
 extended attributes), as this would cause unnecessary rebuilds.

 |interfaces_info| is a dict, keyed by |interface_name|.

 Current keys are:
 * dependencies:
     'implements_interfaces': targets of 'implements' statements
     'referenced_interfaces': reference interfaces that are introspected
                              (currently just targets of [PutForwards])

 * inheritance:
     'ancestors': all ancestor interfaces
     'inherited_extended_attributes': inherited extended attributes
                                      (all controlling memory management)

 * public:
     'is_callback_interface': bool, callback interface or not
     'implemented_as': value of [ImplementedAs=...] on interface (C++ class name)

 * paths:
     'full_path': path to the IDL file, so can lookup an IDL by interface name
     'include_path': path for use in C++ #include directives
     'dependencies_full_paths': paths to dependencies (for merging into main)
     'dependencies_include_paths': paths for use in C++ #include directives
     'dependencies_other_component_full_paths':
         paths to dependencies (cannot merge because of other component)
     'dependencies_other_component_include_paths':
         paths for use in C++ #include directives because of dependencies in
         other component

 Note that all of these are stable information, unlikely to change without
 moving or deleting files (hence requiring a full rebuild anyway) or significant
 code changes (for inherited extended attributes).
