    Creates a document's BasicManager and loads it, if we are already based on

    a storage.

    [Note]

    (with its pStor parameter) and by implementations of <SvPersist::InitNew()>

    (with pStor = 0).

    /*  #163556# (DR) - Handling of recursive calls while creating the Basic

        manager.

        It is possible that (while creating the Basic manager) the code that

        imports the Basic storage wants to access the Basic manager again.

        Especially in VBA compatibility mode, there is code that wants to

        access the "VBA Globals" object which is stored as global UNO constant

        in the Basic manager.

        To achieve correct handling of the recursive calls of this function

        from lcl_getBasicManagerForDocument(), the implementation of the

        function BasicManagerRepository::getDocumentBasicManager() has been

        changed to return the Basic manager currently under construction, when

        called repeatedly.

        The variable pImpl->bBasicInitialized will be set to sal_True after

        construction now, to ensure that the recursive call of the function

        lcl_getBasicManagerForDocument() will be routed into this function too.

        Calling BasicManagerHolder::reset() twice is not a big problem, as it

        does not take ownership but stores only the raw pointer. Owner of all

        Basic managers is the global BasicManagerRepository instance.
