  1. Avoid returning a negative value from Field.get_linelen. 

    A sufficiently messed-up frame (e.g. a player skip) can cause the
linelocs list to be non-monotonic. In PAL mode, ld-decode correctly
reports the TBC failure, but then crashes because demod_pilot is empty.

Fix this by returning the default line length if the length would
otherwise be zero or negative.
