implemented tere_set_is_interrupted_cb()

Allows you to set up a callback that's invoked repeatedly during
matching. If it returns non-0 matching will abort and REG_EINTR is
returned.
Allows you to interrupt long-running regexp executions that would
otherwise block the UI or hang the entire application.
