GitSetup upstream added an attribute to export `.gitattributes` so that
importing snapshots into the sources of other projects would bring along
the attributes.  However, we don't want to export them from CMake.  Drop
`.gitattributes` entries not relevant to CMake.

This allows a single condition to be used to choose between two

Add missing pieces for RelWithDebInfo and MinSizeRel.

Add a space to the imported include directories used for the test.
This works around funny quoted-`;` interpretation by Visual Studio.

Do not duplicate the list of include directories 4 times.

These new global properties were added:

* FeatureSummary_PKG_TYPES: Package types accepted by FeatureSummary
  (default REQUIRED RECOMMENDED OPTIONAL RUNTIME).
* FeatureSummary_REQUIRED_PKG_TYPES: Package types that will cause
  FeatureSummary to abort when called with
  FATAL_ON_MISSING_REQUIRED_PACKAGES and a package in these categories
  is missing (default REQUIRED).
* FeatureSummary_DEFAULT_PKG_TYPE: Default package type assigned when
  not explicitly assigned by the user (default OPTIONAL).

This allows to add and remove new package types that can be printed
selectively using the "WHAT" argument.

This option suppresses the output when the list of packages that belong
to the selected category is empty.

The OPTIONAL type is used anyway as default when the type is not set

Since RUNTIME < OPTIONAL, forcing it here forces the user to set
"RUNTIME" at the first SET_PACKAGE_PROPERTIES, otherwise it is
impossible to set it later.
Without this it is impossible, for example, to add package information
(URL and DESCRIPTION) in the FindPackage file, but allow the package
to be RUNTIME.

* Remove space before commas
* Do not add an empty line before the first type of packages

Also fix a typo in unit test.

At least the scratchbox compiler for the N900, which basically is a gcc 4.2,
sets only __GNUG__ in C++ mode, but not __GNUC__. It does indeed set
__GNUC_MINOR__ and __GNUC_PATCHLEVEL__. Extend the compiler detection code for
GNU compilers in C++ mode to look at __GNUG__ in case __GNUC__ is absent.

The presence of CMAKE_CXX_COMPILE_FEATURES doesn't mean cxx_auto_type is always
available.
