add extern, refactor some term functions

* Add an extern() call. Maybe it should be defined on client. It
  certainly should accept a dictionary instead of the enum type we use
  now. Perhaps it should return the error code?
  I'll leave it undocumented until I figure this out.
* Refactor enableRawMode, unblockStdin, etc. so that they operate on
  the term object instead of global state.
* Move editor to a separate folder, and factor out runprocess into
  a different module.
