Rostislav Pehlivanov ce943dd6ac configure: error out on unsupported MSVC versions
The FATE tests for MSVC versions older than 2013 are untested in FATE
and apparently are no longer supported.

This commit makes the configure process error out in case an older version
is used, and suggests to use a supported version of MSVC to compile.

This also changes the documentation to reflect this.

As discussed on IRC:

2018-05-12 19:45:16     jamrial then again, most of those were for old msvc, and i think we're not supporting versions older than 2013 (first one c99 compliant) anymore
2018-05-12 19:45:43     +JEEB   yea, I think 2013 update 2 is needed

22:53 <@atomnuker> nevcairiel: which commit broke/unsupported support for msvc 2013?
23:23 <@atomnuker> okay, it was JEEB
23:25 <+JEEB> which was for 2012 and older
23:25 <+JEEB> and IIRC we no longer test those in FATE so that was my assumption
23:26 <+JEEB> 2013 is when MS got trolled enough to actually update their C part
23:26 <+JEEB> aand actually advertised FFmpeg support
23:26 <+JEEB> (although it was semi-failing until VS2013 update 1 or 2)

Diego Biurrun 4f9297ac3b build: Prefer NASM assembler over YASM
NASM is more actively maintained and permits generating dependency information
as a sideeffect of assembling, thus cutting build times in half.

Rostislav Pehlivanov 220b24c7c9 lavc: remove libschroedinger encoding and decoding wrappers
The library has stopped being developed and Debian has removed it
from its repositories citing security issues.
The native Dirac decoder supports everything the library has and basic
encoding support is still provided via the native vc2 (Dirac Pro, intra
only version of Dirac) encoder. Hence, there's no reason to still support
linking to the library and potentially leading users into security issues.

Josh de Kock dc0f711459 lavc: remove libfaac wrapper
There is really no need for two aac wrappers, we already have
libfdk-aac which is better. Not to mention that faac doesn't
even support HEv1, or HEv2. It's also under a license which is
unusable for distribution, so it would only be useful to people
who will compile their own ffmpeg, only use it themselves (which
at that point should just use fdk-aac).

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.
>
> © 2008, 3GPP Organizational Partners (ARIB, ATIS, CCSA, ETSI, TTA, TTC).
>
> All rights reserved.

(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
configure):

> Redistribution and use in source and binary forms, with or without
