#3486: SWS bicubiclin resizing filter doesn't work anymore
---------------------------------+--------------------------------------

---------------------------------+--------------------------------------
Summary of the bug: when I try to resize using the bicubiclin algorithm, I
just get an error, while others as sinc, lanczos or vanilla bicubic are
working fine.
Also when trying to programmatically use SWS_BICUBLIN with
sws_getCachedContext(), I get a C runtime exception.
Maybe, SWS_BICUBLIN has been removed from FFmpeg?
How to reproduce:
