avfilter_copy_frame_props() avoids code duplication and increases
robustness.

The added files libavfilter/avcodec.[ch] are used for containing
utilities useful for gluing togheter libavfilter and libavcodec.

Improve consistency with libavcodec.

This breaks libavfilter API/ABI.

The non-sequential 2.1.0 -> 2.4.0 bump is due to the mess previously
done with the lavfi minor number.

The sample aspect ratio is a per-frame property, so it makes sense to
define it in AVFrame rather than in the codec/stream context.
Simplify application-level sample aspect ratio information extraction,
and allow further simplifications.

This is similar to what was done with pkt_pts. This simplifies the
operation of extracting the pos information from the AVPacket, and
allows further simplifications.

Move output_picture() code to queue_picture(), and remove it.
Simplify code path.

The new name is shorter and less confusing.

The new names are less misleading and more reciprocally consistent.

Also automatically select the show mode only if not specified by the
user.

Fix trac issue #109.

In video_image_display(), fix exception occurring when the size of the
rectangle passed to SDL_DisplayYUVOverlay() is 0x0, which happens when
interactively resizing the SDL window.
This is done by forcing the minimum size to 1x1.

The new name is less misleading, since the function will resume the
stream if it is currently paused.

The new option allows to select the starting show mode.

Also rename VideoState->show_audio to show_mode.
Improve readability.

Move up the definition of audio_write_get_buf_size(), so that it is
defined before it is used. Simplify.

When CONFIG_AVFILTER, use a AVFrame -> AVPicture cast rather than
explicitely copy the image information from AVFrame to a new
AVPicture.

In high bit depth the pixels will not be stored in uint8_t like in the
normal case, but in uint16_t. The pixel size is thus 1 in normal bit
depth and 2 in high bit depth.

Preparatory patch for high bit depth h264 decoding support.

Fix crash if ic->pb is NULL and ic->pb->error is evaluated. This
