8b19ae0761 crc: fix signed overflow
This fixes a signed overflow from i << 24 when i == 255 by
making i unsigned.  The result of the shift is already
assigned to an variable of unsigned type.

b3e144a7df des: add possibility to calculate DES-CBC-MAC with small buffer
This patch adds the possibility to calculate the DES-CBC-MAC of a
source buffer (i.e. the last block of the buffer encrypted in CBC
mode) without having to allocate a destination buffer that is as
long as the complete source buffer, but instead only 8 bytes
for the MAC.

They will only ever be <=0 if the option is broken, in which case this

79eff91325 AVOptions: deprecate av_opt_set_defaults2
It's a hack which was created to allow for multiple options with

a726d7fd4e AVOptions: in av_opt_find() don't return named constants unless unit is specified.
That is, unless the caller explicitly asks for them.

Prevents conflict between e.g. the 'loop' option in img2 demuxer and
'loop' flag in AVCodecContext.
