Clément Bœsch 768c47ec37 lavfi: remove mp=pp filter.
Native pp filter is available.

postproc dependency is also dropped from mp wrapper since it was the
only filter needing that dependency.

Clément Bœsch 9b8de93036 lavfi: add pp filter.
Ported from MPlayer. Original author is A'rpi, with various
contributions from Michael Niedermayer. The original documentation was
mostly written by Diego Biurrun. See the MPlayer history for full
credits.

The filter is under GPL like the original filter, even if it differs
quite a lot. There is not much point in making it LGPL since pp is under
GPL.

Clément Bœsch 3bdd70fc66 lavfi/gradfun: reduce up limit for threshold.
This will prevent an overflow in the SSSE3 and MMX filter_line code:
delta is expressed as an u16 being shifted by 2 to the left. If it
overflows, having a strength not above 64 will make sure that m is set
to 0 (making the m*m*delta >> 14 expression void).

A value above 64 should not make any sense unless gradfun is used as a
blur filter.

hqdn3d was meant to be a more efficient denoise3d filter, is supported
natively, and is faster on my computer thanks to the ASM optimisations.

Same calculation as for RGBA etc to create unpremultiplied output.
Useful for creating an intermediate "Mix/Effects bank", in vision mixer
(switcher) terminology.

Example command:

ffmpeg -i input.mov -vf
"[in]scale=iw:ih:interl=1,format=yuv420p[bg];movie=BBC_blocks_watermark.png,scale=iw:ih:interl=1,format=yuva420p[dog];movie=Kickabout_strap.mov,scale=iw:ih:interl=1,format=yuva420p[strap];[strap][dog]overlay=0:0[me1];[bg][me1]overlay=0:0,scale=0:0:interl=1[out]"
-b:v 3M -an output.mov

Fix trac ticket #549.

but a warning is printed if a conflict is likely to happen.
