Recently tons of warnings show up for presumably "problematic"
singned <-> unsigned and size conversions.
The Qt side uses 'int', and that's the biggest 'integration surface'
for us, so instead of establishing some internal boundary between
signed and unsigned areas, push that boundary out of creator core code,
and use 'int' everywhere.
Because it reduces friction further, also do it in libcplusplus.

With this change ClangCodeModel only needs to sort completions by prefix.
Also some other optimization have become possible and are implemented here:
1. Getting completions after '{' for constructor overloads by replacing
it with '(' inside usaved file.
2. Checking for all overloads requires only previous item check because
all Class completions are already sorted to go before all CXXConstructor
completions. Since they are not mixed no extra search is required.

Each completion coming from libclang now has it's own
list of fix-its which are required to be applied before
completion itself.
This saves one extra reparse cycle and gives an ability

one) for cases like shared_ptr, unique_ptr or any other
class with overloaded arrow operator.
Each of these extra fix-its is applied together with
corresponding completion dircetly before completion itself.

Reproduce with:
1. Create a new class named Foo with the wizard.
2. Close foo.h
3. In foo.cpp, add some class member function.
4. In foo.cpp, trigger the refactoring action "Add public Declaration"
for the just defined member function. As a result, foo.h will be
opened.
==> While the declaration was added, the header file is not yet
reparsed with the new content - this can be verified by setting
a custom color for "Function".
In this use case, the refactoring action opens the editor and
immediately modifies the document (RefactoringFile::apply).
Fix by sending the document content along for the very first
RegisterTranslationUnitForEditorMessage if the document was already
