Make the functions av_samples_fill_arrays, av_samples_alloc, and
avcodec_fill_audio_frame return a buffer size rather than 0 in case of
success. This will be enabled at the next libavutil major bump, in order
to preserve backward compatibility.

Returning the size allows to simplify the code, avoiding a few function
calls.

The binary encoder has a "switch field order" setting that
moves one line from the top to the bottom of the frame.

Fixes ticket #966.

Preventing the use of discouraged or 'insecure' external functions
through defines in an internal header is not a good solution. The
header is not guaranteed to be included universally which makes
overlooking bad use of said functions during review more likely.

There are cases were those functions either are the most straight
forward solution or even have to be used. Using malloc or free is
required if the allocation or release is done by other libraries.

Assume that the value is always negative in case of error, as stated in
the docs, do not assume that the value cannot be != 0 in case of success.

The only CPUs that have 3dnow and don't have mmxext are 12 years old.
Moreover, AMD has dropped 3dnow extensions from newer CPUs.

It is handled separately from other types because it uses stream
specifiers and currently that triggers an assert in SET_DICT.

The interface is implemented against the style of the other options
accessors. Possibly simplify programmatic setting of options.

The palette is organised into 'hold' and 'modify' pairs, hence why
the first palette entry is pal[1].

'k', 'M', and 'G' are SI (unit) prefixes or metric prefixes,
not 'number postfixes'. Also, the statement regarding binary
prefixes ("powers of 2 are used instead of powers of 10")
might be misinterpreted (1 kB = 10^3 B, but 1 KiB != 2^3 B).

GCC does not appear to have a -march= string for Westmere, which is a
bit surprising as it has a few more instructions than a Nehalem, but
a few less than a Sandy Bridge.
