The project that was referenced at cppeditor.cpp:711 was already
deleted. CppModelManager::m_fileToProjectParts contained outdated
information. Now it is updated if a project is closed.

Exposed by commit d411c076.

If two files from different (sub-)projects include the same header file,
and the defined macros differ for both files, the header file will be
parsed with only the appropriate macros for the including file.

The model-manager now supports multiple code models for semantic
highlighting and code completion, and will choose one based on the
mime-type of the editor.

The settings page is currently disabled. It will get enabled when a
second plug-in lands that has a ModelManagerSupport class.

Both semantic highlighting and code-completion go hand-in-hand, so now
the ModelManagerSupport class acts as a "factory" for the model manager.
Depending on the mime-type of the document in the editor, the model
manager will return the appropriate highlighter or code-completion
engine. If none is registered, the built-in fall-back is used.

When a file is not part of any other project part, this project part can
be used to get at least some compiler flags, defines, etc. to use. This
can happen when either a file outside a project is opened, or when the
project description is incomplete.

This is step 1 of 2 for merging the various provider factories into a
single class. Merging has the advantage that selecting based on editor
(content) mime-type only has to select one class, instead of re-doing
the selection for each class separately.

And not from the global object pool. This way, the editors that have

(a) The code model manager figures out by itself which files were added
    or removed from the project.

    If this was done successfully, check also the timestamp of the
    common files and reindex if necessary.

(b) A full reindexing is only triggered if the project configuration
    changes (defines, includes, framework paths).

(c) If project files were removed, the garbage collector is called.

Currently GC() is invoked if
   - 5 CppEditors were closed or the last CppEditor was closed
   - a project is about to be removed
   - a session is about to be unloaded

Thus, for the following use cases, too much GC() calls (can) happen:
    - File > Close All
    - Close All Projects and Editors
    - Changing the session

Fixed by introducing a timer.

Track the typical #ifndef/#define/#endif usage in header files to see if
the macro is an include guard. If so, store it in the Document. No
behavioural change, just recording the name.

This can be used in the future to track if a file needs to be re-parsed
when a macro changes: if it was used in the file, and not defined in it
nor being the include-guard, a file should be re-preprocessed and
re-parsed.

It can also be used to check if two files have the same include guard.
