Feeding libclang with unsaved files (e.g. in-memory generated ui_*.h)
that do not exist on disk leads to regeneration of the preamble on every
parse/reparse/completion and thus renders the clang code model useless.
We could check the existence in the file system for every unsaved file
just before every parse/reparse/completion. Obviously this does not
scale (e.g. qtcreator.pro generates about 200 unsaves files) and would
also slow down the responsiveness of the completion, especially for the
dot-to-arrow correction case.
We could also set up a file system watcher. However, implementing the
"file got created" case is not trivial because QFileSystemWatcher does
not support it out of the box.
Instead, set up a custom include directory and create empty files in it
that represent the unsaved files and pass that include directory to
libclang as the last one. While this fixes the performance problems, it
also comes with at least two problems:
* Because ui_*.h files are "relocated" to the same directory, two or
more "foo.ui" in the same session will be problematic.
* Because of the custom include directory, problems might arise for
projects that include the ui_*.h as "some/relative/path/ui_foo.h"
instead of "ui_foo.h". This should be the less common case.

Most of the time, the updated diagnostics/highlightings will be send by
the backend on translation unit update.
The other use case is changing the font settings (e.g. color), here we
need to request the highlightings explicitly.

Fix the following use case:
* Open foo.h
* Open foo.cpp
* Change both files externally (e.g. git checkout) e.g. by adding a
function (declaration + definition)
* Confirm the reload dialog in Qt Creator
* The added function in foo.cpp gets a diagnostic that it's out of line
although foo.h is also reloaded.
TextDocument::contentsChangedWithPosition() is also emitted during a
reload. However, the revision of the document at that point is not yet
updated. This led to an out-dated copy of the unsaved files in the clang
backend.

Ensure that first the editors unregister with the removed project part,
then unregister the project part.
This makes testing and following the message logs easier.
It also fixes the following race condition:
* Unload project of opened file
* Immediately close the editor before a new project part is calculated
==> The editor is closed, but the translation unit is not properly
unregistered.

They are invokable by the usual means (Alt+Enter, editor's context menu

related line.
The fixit text comes directly from libclang and is thus not translated.
We modify the text slighty by stripping the diagnostic category prefix
("note:", "error:", ...) and capitalizing the first letter.
A follow-up change should properly indicate available refactorings with
a refactoring icon in the editor's left margin.

This mainly takes CppEditorSupport apart.
* Parsing is now invoked by CPPEditorDocument itself by listening to
QTextDocument::contentsChanged().
* Upon construction and destruction CPPEditorDocument creates and
deletes an EditorDocumentHandle for (un)registration in the model
manager. This handle provides everything to generate the working copy
and to access the editor document processor.
* A CPPEditorDocument owns a BaseEditorDocumentProcessor instance that
controls parsing, semantic info recalculation and the semantic
highlighting for the document. This is more or less what is left from
CppEditorSupport and can be considered as the backend of a
CPPEditorDocument. CPPEditorDocument itself is quite small.
* BuiltinEditorDocumentProcessor and ClangEditorDocumentProcessor
derive from BaseEditorDocumentProcessor and implement the gaps.
* Since the semantic info calculation was bound to the widget, it
also calculated the local uses, which depend on the cursor
position. This calculation got moved into the extracted class
UseSeletionsUpdater in the cppeditor plugin, which is run once the
cursor position changes or the semantic info document is updated.
* Some more logic got extracted:
- SemanticInfoUpdater (logic was in CppEditorSupport)
- SemanticHighlighter (logic was in CppEditorSupport)
* The *Parser and *Processor classes can be easily accessed by the
static function get().
* CppHighlightingSupport is gone since it turned out to be useless.
* The editor dependency in CompletionAssistProviders is gone since we
actually only need the file path now.
