Add support for the location change state machine and related

* src/ntl-types.h, src/ntl-uri-map.[ch], src/ntl-window-msgs.c, src/ntl-window.[ch]:
  Add support for the location change state machine and related notifications,
  to allow much better error handling.

* src/ntl-view.[ch]: Catch client failures, also allow for active sensing of client death.
* src/file-manager/fm-directory-view.c: Send progress notifications.
* components/html/ntl-web-browser.c: Send progress
  notifications. Try to fix crashes caused by ending an error stream
  twice.
