Express the allocation of a new view handle by a dedicated RPC function
instead of passing an invalid view handle to the existing 'view_handle'
function.
This eliminates the notion of invalid view handles at the GUI session
interface, clearing the way for managing view handles via an Id_space.
Issue #5242
- Rename framebuffer_session to framebuffer and
input_session to input as those RPC interfaces are no longer
meant to be used as stand-alone sessions.
- Host Connection::input and Connection::framebuffer as public
members, thereby removing the use of pointers. This simplifies
the client-sized code. E.g., '_gui.input()->pending()' becomes
'_gui.input.pending()'.
Issue #5242
To maintain ease of use at the client side, the OUT_OF_RAM and
OUT_OF_CAPS results are handled at the 'Gui::Connection' now.
Gui::Connection does not inherit the Gui::Session interface any longer,
which allows for the use of different result types.

Issue #5245
This patch replaces the optional parent argument of the create_view
RPC function by a dedicated create_child_view RPC function. This
is a preparatory step of removing the notion of an invalid handle
as a special case.
Issue #5242
- Replace 'typedef' by 'using'
- Avoid plain pointers
- Import Genode namespace into Gui::
- Use enum class
- Use Attr struct for passing multiple attributes
- Turn testnit into proper Genode::Component
- Use distinct types for top-level and child views
- Remove dependency from timer
- Use util/geometry.h
