...which was least buggy.

The bugs fixed by the changes we revert here (highlighting/completion
for code involving templates) were minor compared to ones we currently
have. Those bugs will be addressed by the clang code model anyway.

Relevant commits were collected via:

  $ cd ${QTC}/src/libs/cplusplus
  $ git log \
   --no-merges \
   --format=oneline \
   v3.4.2..HEAD \
   -- LookupContext.* ResolveExpression.* TypeResolver.* TypeOfExpression.* \
      ../../plugins/cpptools/cppcompletion_test.cpp

From this list the following were skipped due to irrelevance:

  88c5b47e # CppTools: Minor cleanup in completion tests
  e5255a1f # CppTools: Add a test for ObjC not replacing dot with arrow
  5b12c8d6 # CppTools: Support ObjC in member access operator tests
  9fef4fb9 # CPlusPlus: Fix warnings about overriding visit(...) methods

There were only minor conflicts while reverting those.

This changes touches so many files because there were quite some
cleanups and renames after the 3.4.2 release.

The functionality in that class is covered by initializers and
Utils::unique, so there is no need to keep a custom class.

This way FileNameList plays way nicer with utils/algorithm.h.

    Modify CppModel::ProjectInfo

    Adding per project node information, to pass on the correct
    defines/includes for each file, instead of aggregating them incorrectly.

    Also split up SOURCES and OBJECTIVE_SOURCES.

    Also ask the toolchain to convert the compilerflags to flags the
    codemodel understands, for now only gcc and only c++11.

    Also make the toolchain aware of the flags used to compile, so that it
    can emit the correct defines.

    Note: No header files are passed on.

Now the type hierarchy widget will also show the classes
derived from the selected one. For consistency the way
the base classes are shown was changed too. The diagram
below is an example from Creator's code when openining
the type hierarchy for BaseTextEditorWidget:

Bases
 +QObject
  +QWidget
   +...
     BaseTextEditorWidget
 +QPaintDevice
  +...
    BaseTextEditorWidget
Derived
 +BaseTextEditorWidget
  +VCSBaseEditorWidget
    GitEditor
    MercurialEditor
    ...
   GLSLEditorWidget
   CppEditorWidget
   QmlJSTextEditorWidget
   ...

Depending on the project and on the selected class the
hierarchy widget might take a bit to be constructed.
This should be improved later.
