hyscale, hcscale are only used in old filter code, hence place
header guard to silence -Wunused-function.

This resolves implementation defined behavior, and also silences -Wabsolute-value in clang 3.5+.
Moreover, the generated asm is identical to before modulo nop padding.

dcadec: scan for extensions in a separate function

Add an allowed parameter to -h and --help avconv option to print private
options from a codec, format, or filter, named with the provided input
value.
In case multiple classes are found (eg. mov demuxer and mov muxer, or
h264 decoder and h264 demuxer) print all options from all classes.
It is possible to select the type of class to print by adding it
before the name (eg. demuxer:mov and muxer:mov, or decoder:h264and
demuxer:h264).

This patch refactors the AAC coders to reuse code
between the MIPS port and the regular, portable C code.
There were two main functions that had to use
hand-optimized versions of quantization code:
- search_for_quantizers_twoloop
- codebook_trellis_rate
Those two were split into their own template header
files so they can be inlined inside both the MIPS port
and the generic code. In each context, they'll link
to their specialized implementations, and thus be
optimized by the compiler.
This approach I believe is better than maintaining
several copies of each function. As past experience has
proven, having to keep those in sync was error prone.
In this way, they will remain in sync by default.
Also, an implementation of the dequantized output
argument for the optimized quantize_and_encode
functions is included in the patch. While the current
implementation of search_for_pred still isn't using
it, future iterations of main prediction probably will.
It should not imply any measurable performance hit while
not being used.
Failing earlier causes the context to be insufficiently initialized which
can break decoding future frames with threads

gamma_convert is only used with the old code. Thus, it is
placed under a header guard. This patch silences a -Wunused-function
observed on GCC 5.2.
