998c9f15d1 idct: remove call to ff_idctdsp_init from ff_MPV_common_init 
One step in untangling the mpegvideo code and fixing some problems in
the order that initialization is being done in h263dec and h261dec.

f6774f905f mpegvideo: operate with pointers to AVFrames instead of whole structs 
The most interesting parts are initialization in ff_MPV_common_init() and
uninitialization in ff_MPV_common_end().

ff_mpeg_unref_picture and ff_thread_release_buffer have additional NULL
checks for Picture.f, because these functions can be called on
uninitialized or partially initialized Pictures.

NULL pointer checks are added to ff_thread_release_buffer() stub function.

ebfe622bb1 mpegvideo: drop support for real (non-emulated) edges 
Several decoders disable those anyway and they are not measurably faster
on x86. They might be somewhat faster on other platforms due to missing
emu edge SIMD, but the gain is not large enough (and those decoders
relevant enough) to justify the added complexity.

02beb9826b lavc: deprecate AVCodecContext.sub_id. 
In most places where it's used, it's as a pointless write-only field.

Only rv10 decoder actually reads from it, but it stores some internal
version info in it. There is no reason for it to be in a public field.

9791c02733 Saner RV1/2 initialisation and RV2 header parsing. 
Old version was based on lots of guesswork which had different hacks based on
32-bit version field instead of splitting it into major/minor/micro version.
RV2 picture header parser also had a few places where it deviated from binary
decoder.
