Andreas Rheinhardt 2273902be8 avfilter/lavfutils: Avoid copying frame in ff_load_image()
Return the data in an AVFrame instead. This is what several users
({find,cover}_rect*) want anyway. This also avoids accessing
AVFrame.format (an int) via an enum AVPixelFormat*.

*: This commit actually avoids two frame copies For find_rect:
av_frame_clone() contained an implicit alloc+copy.
