ffv1: avoid checking a double for equality

if 0.0 != 0.0 a out of array read would occur, equal checks
with floating point may behave in such odd ways, though
this is very unlikely in a real implementation of a compiler

Fix writing 12 bit DPX

The DPX encoder now writes 12 DPX that open correctly (tested with
ImageMagick), and also correspond to the 12 bit sample files at
http://samples.ffmpeg.org/image-samples/dpx_samples.zip

Fix DPX decoder

Rewrite the DPX decoder to work with provided sample DPXs at
http://samples.ffmpeg.org/image-samples/dpx_samples.zip

The decoder could only decode 8 and 10 bit without alpha correctly,
failing or even crashing at other flavors. This patch aims to fix
these issues, properly decoding all variants of DPX provided in the
referenced DPX sample zip. For 10 and 12 bit, the alpha channel
is ignored, but decoding is still possible.

Revert "configure: link flite against libasound"

This reverts commit 396648cc6a3eb5c00c698555fa4ddd631bf6664d.

The commit made impossible to build against libflite if libasound is not
available (e.g. on Windows). Thus remove the -lasound flag. In case of
libflite static linking the workaround is to enable
--extra-ldflags=-lasound (or disable the ALSA output device in libflite).

libflite depends on libasound. Fix a linking failure when linking against
