Disable use of assembly on MIPS to allow it to build. MIPS is not
expected to be high performance in OpenWrt, and this allows it to still
be used for media identification as updated versions of ffmpeg are
brought in.
The error is in
libavcodec/mips/aacdec_mips.c: In function 'imdct_and_windowing_mips'
regarding: 'asm' has impossible constraints in multiple locations.

libx264 will be included in both hard & soft float libffmpeg-full builds if selected
and BUILD_PATENTED=y. Otherwise, it is not included in libffmpeg-full

Hard float includes: libx264, mp3lame

fdk-aac will not be available in libffmpeg-full due to incompatible license with libx264.

Change libffmpeg-full to, by default, use the LGPL license. This
allows libffmpeg-full to gain support for libfdk-aac.
When libx264 is selected, this changes to GPL, and libfdk-aac
support is lost. Libx264 support is prioritized when both are
selected, which maintains the status quo of what happens now.

Have encoders and demuxers selectively disabled for patents in
libffmpeg-full too. Assume same codecs covered as decoders and
muxers, respectively. Include vc1 in muxer's too.
Don't invoke --enable-nonfree in libffmpeg-full. It results in:

Build depends refer to source package names, not binary package names.
In many cases, PKG_BUILD_DEPENDS simply duplicated runtime dependencies of
a source package's binary packages; as the corresponding source packages
are implicitly added as bulid dependencies, PKG_BUILD_DEPENDS can simply be
dropped in these cases. In the other cases, *_BUILD_DEPENDS is fixed to
refer to the correct source package name.
Dependency of mysql-server is adjusted from libncursesw to libncurses
(as libncursesw is a virtual package provided by libncurses), so the build
dependency on ncurses is emitted unconditionally.

This toggles on Link-Time Optimization for arm and x86-64.
Compile tested on arm/bcm47xx, arm/mvebu, arm/imx6 and x86-64/generic
(Also compile tested on mips/ar71xx where it failed so this change is currently for specific arches.)
Size savings for libffmpeg were 2-3% when measured with libffmpeg-full and libffmpeg-mini.

This change allows ffmpeg's configure script to determine the necessary parsers based on
selected decoders & encoders. For libffmpeg-audio-dec, this changes from our selecting:
aac, ac3, flac, mpegaudio, opus and aac_latm
to ffmpeg's configure script selecting:
aac_latm, ac3, flac, mpegaudio
for minor space savings and a simpler Makefile to manage on our end.
In libffmpeg-custom, don't select any parsers when choosing decoders/encoders. I'm undecided
on removing the parser selection in its entirety here.

Removes the x86 optimization disables from the SOFT_FLOAT portion. There are no i386 profiles that do
not use hard float, so these options accomplish nothing.
Target-os=linux rules out dxva2 and vda, so disable statements are unnecessary.
For x86-64 users of libffmpeg-full, optimize around performance instead of size.
Remove patented flag requirement from mp2 and mp3 audio files in libffmpeg-custom per expiration.
Tidies up some of the configure steps where only one option is being changed or cosmetic consistency.

Also makes the following changes:
Updates project URL and moves libpthread to a common dependency;
Makes libopus support in libffmpeg-full contingent on selecting the
libopus package, like other external libraries;
Adds note regarding disabling altivec in ppc hard-float;
Reorganizes SIMD sections to be together;
Drops the need to specify decoder=libopus from -full, done by default;
Adds encoder=libopus to custom.
Expand options for libffmpeg-custom:

Drops version 3 of GPL for -audio-dec, -mini, and -full. Version 3 is
at the discretion of the packager, per:

Update ffmpeg to 2.8.8.
Adds HEVC, Opus, VC-1 and Vorbis to custom and minidlna profiles. This should
more closely match formats media being streamed on the local network via
DLNA/UPNP.
Removes raw aac, ac3 and h264 from minidlna profile. Most players expect
this content to come within a container (mkv, mov, mp4, mpegts, etc...),
so this was unnecessary for the profile's goals.
Remove libopus from being selected by the -custom's audio-dec profile, and as
a depend on -audio-dec. -audio-dec uses ffmpeg's internal Opus decoder, not
the external library.
Don't select specific parsers in libffmpeg-mini profile. The demuxers separate
streams from containers. Parsers break up the streams. These are not needed
for DLNA/UPNP. If a parser is needed, the ffmpeg configure script should grab
it.

Also no longer disable run-time CPU detection for fpu targets except
arm which is built for each variant (neon, vfp).
This vastly improves performance on x86 which now supports building ASM
code with yasm and makes use of a broad spectrum of extensions
depending on their availability at run-time.
In future, such differentiation should also be introduced for MIPS
to at least conditionally enable the output of MIPS32r2 instructions as
well as DSPr1 and DSPr2 if the target supports that dispite them having
CONFIG_SOFT_FLOAT=y set.

For libffmpeg-audio-dec:
Remove @DEVEL flag from libffmpeg-audio-dec. Reasoning for this is
that choosing this package does not rquire any further action by the
builder in what codecs or formats should be built in.
libffmpeg-custom, the other libffmpeg to require @DEVEL, does need
further interaction.
Add @BUILD_PATENTED as at least one of the audio codecs is likely
patent protected.
Add ffmpeg's native Opus decoder to libffmpeg-audio-dec
Remove libopus dependency to libffmpeg-audio-dec as libopus provides
decode and encode support for Opus audio. Since FFmpeg can decode
Opus audio on its own, and libffmpeg-audio-dec is intended for audio
decoding, libopus is no longer required for Opus audio support.
For libffmpeg-custom:
Add in options for ffmpeg's integrated Opus decoder
