Timothy Gu 54220ce731 pixfmt: Use enum assignment for aliases 
This way, Doxygen is happier as aliases are now grouped together, and
it never handled #define's in an enum well in the first place.

Y400A already exists as an enum assignment.

  avconv: fix handling attachments in init_output_stream

Conflicts:

This is functionally a no-op, as we don't have the bug this is trying to
fix. See 843be56ee1.

Timothy Gu cb8646af24 configure: Enable GCC vectorization on ≥4.9 on x86 
4.9 was released precisely nine years after the first GCC version with
autovectorizer (4.0) and six years after the first GCC version with
`-ftree-vectorize` default to enabled on `-O3` (4.3). We've given GCC
enough time to fix those bugs.

FATE passes here on a x86-64 machine with both GCC 4.9.2 and 5.3.1.

Some optimization hotspots benefit greatly from this change, especially
those without handwritten assembly. For instance, the main function in
vf_phase is now 1.6x faster (1.2x overall) on my machine.

Timothy Gu 9ba54c1b82 avcodec: Remove libaacplus 
TODO: bump minor

It's inferior in quality to fdk-aac and has an arguably more problematic
license.

As early as 2012, a HydrogenAudio user reported:

> It has however one huge advantage: much better quality at low bitrates than
> faac and libaacplus.

(https://hydrogenaud.io/index.php?PHPSESSID=ckiq394pdglka0kj2fin6ij8t7&topic=95989.msg804633#msg804633)

I myself have made a few spectrograms for a comparison of the two
encoders as well. The FDK output is consistently better than the
libaacplus one, in all bitrates I tested.

libaacplus license is 3GPP + LGPLv2. 3GPP copyright notice is completely
proprietory, as follows:

> No part may be reproduced except as authorized by written permission.

> The copyright and the foregoing restriction extend to reproduction in
> all media.

(The latest 26410-d00 zip from 3GPP has the same notice, but the copyright
year is changed to 2015)

The copyright part of the FDK AAC license (section 2) is a copyleft
license that permits redistribution under certain conditions (and
therefore the LGPL + libfdk-aac combination is not prohibited by
