Add Input::Session::exclusive() interface

Browse Source 
This interface allows a GUI client to express the intent to exclusively
observe relative motion events while locking the absolute pointer
position. This patch merely extends the interface without implementing
it.

As this change touches os/include/input/component.h, it moves the
manage/dissolve operations into the class, ensuring the call of
dissolve at destruction time.
