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.
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).

rtmpproto: Support alternative slist parameter in rtmp URLs

Support the URL scheme where the playpath is in an RTMP URL is
passed as the slist argument and the app is given infront of the
query part of the URL:

rtmp://host[:port]/[app]?slist=[playpath]

(other arguments in the query part are stripped as they are not used)

lavc: Add an internal wrapper around get_format()

It will be useful in the following commits.
lavc: set AVCodecContext.hwaccel in ff_get_format()

This way each decoder does not have to do the same thing manually.
lavc: document which parts of AVHWAccel are private.
hwaccel: Rename priv_data_size to frame_priv_data_size

This describes more accurately what this field is for.
hwaccel: Support specific frame allocators

It would reduce the boilerplate code users have to write.
lavc: Add hwaccel private data and init/uninit callbacks
lavu: Add a pixel format for new VDA hwaccel

The current hwaccel is broken and cannot be fixed in a compatible
way. It will be deprecated and replaced with a new one.
vda: use hwaccel private data for internal bitstream buffer
lavc: Add new VDA hwaccel

It leverages the new hwaccel 1.2 features:

- get_buffer2 is never called
- the internal context is automatically initialized/deinitialized
