The existing code expected a palette buffer holding 256 uint32_t's allocated in the data[1] field of the AVFrame structure, but data[1] was NULL. The bug is fixed by using a fixed local array (palette256) to hold the palette instead.

Fixes ticket #787.

Fixes ticket #767.

Avoid out-of-buffer data access when nb_channels is 8.

av_samples_alloc() behavior changed in bbb46f3e, resulting in random
data filling the data[] and linesize[] arrays of the returned
AVFilterBufferRef, which was resulting in wrong behavior in case of code
checking on data[i] nullity.

In particular fixes crash in avfilter_filter_samples():
        for (i = 0; samplesref->data[i]; i++)
            memcpy(link->cur_buf->data[i], samplesref->data[i], samplesref->linesize[0]);

and correctly fills the linesize[] array for planar data.

The traces end up not indented and ugly anyway, but with the additional
spaces are much more painful to grep/parse.

Originally, prior to 8742a4ff, the caller code was compiled
within this condition:

ARCH_X86 && HAVE_7REGS && HAVE_EBX_AVAILABLE && !defined(BROKEN_RELOCATIONS)

Since HAVE_7REGS is defined as
(ARCH_X86_64 || (HAVE_EBX_AVAILABLE && HAVE_EBP_AVAILABLE))
the subcondition HAVE_7REGS && HAVE_EBX_AVAILABLE is equal
to HAVE_7REGS (for 32 bit at least). The correct simplification
of the original condition thus is HAVE_7REGS, not
HAVE_EBX_AVAILABLE.

This fixes compilation in some cases where HAVE_EBP_AVAILABLE = 0
and HAVE_EBX_AVAILABLE = 1.
