BridgeSupport handling QuartzCore

This is how BridgeSupport generates XML descriptions of a framework : it collects the framework's structures, methods, enums and generates C files to get their Type Encodings, parses the output, and stores the result in a .bridgesupport file. This renders C functions, enums and structures usable in any language once you add some bridging code. This is how RubyCocoa can access the system's frameworks.

Below is a log of BridgeSupport describing QuartzCore, called with :

gen_bridge_metadata.rb -f /System/Library/Frameworks/QuartzCore.framework -c '-framework QuartzCore -F/System/Library/Frameworks/QuartzCore.framework'.
(Some logging code added in gen_bridge_metadata.rb's compile_and_execute_code to display generated code and its output).
