avconv: simplify exit_program() by using more local vars
avconv: rename InputStream.opts to InputStream.decoder_opts

This makes it more clear what is this variable for exactly.
avconv: rename 'icodec' to 'dec_ctx'

This more clearly describes what is the variable used for.
avconv: rename 'codec' to 'enc_ctx'

This more clearly describes what is the variable used for.

Also, move its declaration into the block where it is actually used.
avconv: remove a useless line

Doing anything with that field when we are doing streamcopy (so the
encoder is not opened) should have absolutely no effect.
avconv: rename OutputStream.opts to OutputStream.encoder_opts

This makes it more clear what is this variable for exactly.
avisynth: set duration of audio streams

libfdk-aacenc: Enable 7.1 channel encoding

7.1(wide) and 7.1(wide-side) channel layouts are supported in
fdk-aac since the 0.1.3 release.

The earlier versions of fdk-aac didn't include any library
version defines in the public headers, thus checking for
the AACENCODER_LIB_VL0 define is enough to know that we're
building against a new enough version of fdk-aac.

This change includes contributions by Tim Walker,
Michael Niedermayer and Timothy Gu.

libfdk-aac: Relicense the library wrappers to 2-clause BSD

This should make it possible for Fraunhofer to contribute to these
wrappers - they didn't want to contribute to code under LGPL2.1 with
the "or any later version" clause (which allowed using the code
under the LGPL3 license).

<Daemon404> so it should be fine to merge.
