vf_overlay: implement poll_frame()
...
Signal that it can output a frame when there are frames on the main
input and EOF on the overlay input, but a frame is buffered -- e.g.
single picture overlay.

avfiltergraph: try to reduce format conversions in filters.
...
Current code, with a filterchain such as
(input - yuv411) -> (scale - any) -> (sink - any)
will result in yuv420 being chosen for the second link, which is clearly
not right.
This commit attempts to improve in the following way:
repeat until convergence:
loop over all filters
find input link with exactly one format
force this format on all output links of the same type (if possible)

drawtext: add 'fix_bounds' option on coords fixing

Add 'fix_bounds', to make it usable in such cases (by setting its value to 0).
Default behavior is not changed, and non-fitting text coords are fixed.

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).

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.

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".
