This patch introduces FFT windowing routines to reduce spectral leakage in
spectrum-based visualizations.  It supports four types of windows that are
commonly used in spectrum analyzers (besides the pre-existing rectangular
window):  Hann, flat top, Blackman-Harris, and Kaiser.

For instance changing from 10:10 to 1:1 should not generate an event
if we are not in display fill mode.

Avoid signalling a change of aspect-ratio when it only changed from
1:1 to 0:0.

BluRay streams have 4-byte header before TS sync byte. Current code handles 192-byte ts packets,
but it assumes extra bytes are at the end of packet. This results in re-sync at stream start:
  1) first packet is dropped
     First packet is usually PAT, and losing it means losing the first GOP.
     This is fatal with still-image based menus.
  2) 4-byte header of the second packet is skipped
     This results in read of the last packet returning only 188 bytes,
     and it is also skipped.

A maximum display time does not make sense for real teletext pages. Instead
they should be displayed until the user disables teletext or the page is
updated. Therefore do not set a stop timestamp on normal pages, but only when
rendering in text mode, which is meant for subtitles, where the timeout makes
sense.

The user can choose to apply a builtin shader using a selection list
in the options of the Direct3D vout module. A custom shader function
can also be loaded by specifying the path of the shader file.

Many changes since the latest patch proposal: we are not compiling
"shader techniques" anymore but now shader functions using the "main"
entrypoint.  All the shaders previously in pixelShader.fx are now
builtins.

Based on the code by Sasha Koruga for GSoC 2010.

There is no way in the MediaCodec API for the decoder to signal
these values to the caller, at least none that is publicly
documented.

If the input format has a valid pixel aspect ratio set (ie from the
packetizer) pass this into the output format. This helps for omx
implementations which do not report the aspect ratio.
For omx implementations which provide aspect ratio information give these
precedence over the incoming values.

When the packetizer detects a valid pixel aspect ratio this should be
forwarded to the decoders input format. This is helpful for decoder modules
which do not expose the aspect ratio on their own.

This is consistent with all the other neon functions. This avoids
having to add a symbol prefix via other means (macros, wrapper
tools) on platforms that normally use one.

Fixes Bink video playback. The Bink video decoder in libavcodec relies
on the fourcc to determine the version of the codec.

This avoids reuploading a full resolution 32 bpp surface for
every frame while the subtitles are displayed.

Ideally this information perhaps should be signalled from the vlc
core in some way, but until then, this avoids excessive slowdowns
with subtitles with the mediacodec direct rendering.
