patches: fix all compile errors and review issues

- ZV_S -> BUF_ZV (undefined macro)
- cf->current_buffer -> XWINDOW(cf->selected_window)->contents
  (current_buffer is a thread macro, can't use as field name)
- find_newline: add record_unwind_current_buffer + set_buffer_internal_1
- ns_zoom_track_completion: add specpdl unwind protection
- ns_zoom_face_is_selected: replace with forward decl of ns_ax_face_is_selected
  (eliminates duplicate)
- childFrameLastBuffer: struct buffer * -> Lisp_Object (safe vs kill-buffer)
- EmacsView dealloc: xfree childFrameLastCandidate (memory leak)
- postCompletionAnnouncementForBuffer: add block_input/unblock_input
