e1d9dbf2d4 lavfi: add a new function av_buffersrc_buffer(). 
It can be used to directly pass a AVFilterBufferRef to lavfi, avoiding a
memcpy.

1c9e340d35 lavfi: add avfilter_copy_frame_props()

b58dbb5b03 lavc: add a sample_aspect_ratio field to AVFrame 
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.

e555119c73 mandelbrot: correct and simplify the formula used in NORMALIZED_ITERATION_COUNT 
Use log(sqrt(mb->bailout)) instead of log(mb->bailout) because mb->bailout represent
the bailout radius squared, and then simplify the two sqrt().
This is also slightly faster.
