Alexander Strasser baad01d8b4 h264: improve checks before calling ff_h264_decode_extradata 
The ff_h264_decode_extradata routine now checks for the buffer size
and pointer internally. This makes it possible to remove the external
checks in ff_h264_decode_init.

  In decode_frame there was a size check missing because the buffer
gets tested prior to the invocation of ff_h264_decode_extradata().

Alexander Strasser 715f259bf9 h264: ff_h264_decode_extradata: check buffer args 
The buffer size and pointer were not checked prior to testing the first
byte of the buffer. These were sometimes checked before calling, but it is
better to add it inside the function as it takes buf and size arguments.

Reimar Döffinger 424bcc46b5 Compile x86/swscale_template with -mno-red-zone. 
Replaces a very hackish hack to fix the same issue (call instruction
overwriting stack variables).
