gtk_text_iter_get_line and get_line_offset work fine on the end iter. Don't bail if we are at the end of buffer.

Fixes one part of bug #1516281, the other part is controversial and probably not reasonable to change.
Also deal with NULL being passed as the x or y pointer, as is done also on wxMSW (this was done on 2.6 branch as
well, but not noted).
