5bb5c1dc86 Add AVFilterPicRef.pos field and make libavfilter propagate stream
byte position information, as stored in the pkt.pos, through the
filterchain.

Note that the pos field is added *non* at the end of the
AVFilterPicRef struct, thus breaking ABI compatibility, which is
allowed as the API is still considered non-stable.

b4b6645655 Avoid usage of avcodec_get_pix_fmt_name() and
avcodec_get_chroma_sub_sample(), directly access
av_pix_fmt_descriptors instead.

a13a543797 Add a slice_dir parameter to avfilter_draw_slice().
Avoid the need to implement slice direction detection code, thus
reducing code duplication.

86a60fa1ac Implement a new registration system for filters.
Create a new static array containing pointers to the AVFilter
definitions, so that the non-constant next filter in the AVFilter
struct is not anymore required and the AVFilter definitions may be
stored in shareable memory.

Also change the signature for avfilter_register(), make it return an
int since it may fail if there is not enough space in the static array
for the registered filters.

da23d42476 Make avfilter_get_video_buffer() use
avfilter_default_get_video_buffer() if the get_video_buffer() callback
is not defined in a filter.

Libavfilter filters author have to explicitely define the
get_video_buffer() callback if they want the buffer to be requested to
the filter following in the filterchain.

See the thread:
"[FFmpeg-devel] [PATCH] Make avfilter_get_video_buffer() use
default_get_video_buffer if callback not defined".

3555d2e88e Introduce first_avfilter and use that, together with AVFilter.next,
for registering and finding filters, rather than use the struct
AVFilterList, which is removed.

9dd08b4e1e Fix recursive avfilter_poll_frame(). It was doing
min = FFMIN(min, avfilter_poll_frame(link->src->inputs[i]))
which, since FFMIN is a macro, was calling itself
twice for every input, causing an exponential cost in time.

0eb4ff9e37 Make avfilter_get_video_buffer() recursive.
When called on a link with a filter whose destination pad has not a
get_video_buffer callback defined, it will call
avfilter_get_video_buffer() on the first output link of the
destination filer, rather than use avfilter_default_get_buffer(), so
the video buffer can be allocated forward in the filterchain.

Also add the w and h parameters to avfilter_get_video_buffer(), as the
minimum width and height requested by each filter in the filterchain
may change, this allows for example a memcpy-less pad filter.

This change breaks API / ABI backward compatibility.

See the thread:
"[PATCH] Implement recusive avfilter_get_video_buffer()".
