Based on the libavfilter SOC filter by Vitor Sessak, with the following additions:
* integer arithmetic
* bilinear interpolation
* RGB path
* configurable parametric angle, output width and height

This fixes #2657.
ISML movies produced by Microsoft Expression Encoder 4 seem to have invalid
sample entries in their trun/tfhd for data tracks. As a result, too much bytes
are read for these tracks to the point that next_root_atom can go out of
buffer, which makes the encoding fail if the input is not seekable.

This avoids warnings about this option not having any effect on
this platform.

We still want to enable the pic configure item for these platforms
(if detected via the compiler builtin define __PIC__) to get proper
inline assembly workarounds.

This reverts e08c946c and 05165c2f. The actual intention of
e08c946c was to fix shared library builds for arm/win32, which
can also be accomplished in other ways.

Disabling pic on those platforms broke inline assembly on cygwin/64
(since some inline assembly requires knowing whether we are building
as PIC or not), and might also break inline assembly on other
compilers on windows.

As a side-effect, this unfortunately brings back all the warnings
about PIC not having any effect on that platform.

Also prevents an error since the native decoder (if enabled) is
always used to probe Ut Video-encoded files, even if the user
forces libutvideo to be the decoder. Without this patch, the probe
would fail, and the video wouldn't get properly handed over,
resulting in failure to set codec parameters. When the native
decoder is disabled, libutvideo can probe and initialize decoding
without issues.
