bebe72f4a0 lavc: deprecate FF_*_TYPE macros in favor of AV_PICTURE_TYPE_* enums 
Also deprecate av_get_pict_type_char() in favor of
av_get_picture_type_char().

The new enum and av_get_picture_type_char() are defined in libavutil.
This allows the use in libavfilter without the need to link against
libavcodec.

b04d1abb40 fade: fix draw_slice() check on fade->factor value 
draw_slice() checks that the fade factor is < 65536 and only
calculates the fade if so. But the fade factor is clipped in
end_frame() by av_clip_uint16() to 65535, so the fade is calculated
for every frame.  This patch alters the check so that it compares with
< 65535 (UINT16_MAX).

737eb5976f Merge libavcore into libavutil 
It is pretty hopeless that other considerable projects will adopt
libavutil alone in other projects. Projects that need small footprint
are better off with more specialized libraries such as gnulib or rather
just copy the necessary parts that they need. With this in mind, nobody
is helped by having libavutil and libavcore split. In order to ease
maintenance inside and around FFmpeg and to reduce confusion where to
put common code, avcore's functionality is merged (back) to avutil.

3e5bc7ff6a In the start_frame() debug log, print the reference pos value rather than the evaluated value converted to int. 
That's required because -1 is evaluated as NAN, which converted back

debugging sources with undefined pos (as the video4linux2 device).

    The vflip filter does not need to keep ownership of a picture reference.
    Avoid creating and releasing useless extra picture references in the
    start_frame and end_frame callbacks.

    Originally committed as revision 22596 to svn://svn.ffmpeg.org/ffmpeg/trunk

The new reference creation is required when the linesizes are used by the
previous filters in the filterchain, for example as in "pad=W:H:X:Y,vflip".
