Use ref-counting to make editwin ownership saner When creating an editwin, one creates an editcontext which takes a reference to the editwin. Likewise, the pointer in owl_global holds reference. The reference counting manages their ownership claims. In addition, owl_global_set_typwin_inactive now does release a reference. Instead, the callback-calling commands take a reference and release it later. We may wish to further improve that so that the contexts are also ref-counted such that, when their commands are running, they will not be deallocated, even if popped. That will avoid the callback dance.
