Features: Add cxx_auto_type. Record the availability of this feature for GNU 4.8 on (UNIX AND NOT APPLE) only. In the future, availability can be recorded for earlier GNU, for other platforms and for other compilers. Initially the affected configurations are as restricted as possible to allow for easy testing while extending the features vector in only one dimension. The error message when using the set_property API directly is not very good, but follow up commits will provide origin debugging of the property and a target_compile_features command which will provide a configure-time backtrace when possible.
