Scott Prager b6296f4e84 terminal: Handle loss of focus in event loop.
While in a terminal and insert mode, if an event caused loss of focus,
nvim would stay in the terminal event loop causing an inconsistent view
of internal state and/or segfault.

Remove the "term" argument from terminal_enter() as it only makes sense
to call it with curbuf->terminal. Terminate the loop when switched to a
different buffer.
