* Need to do it for other interface.
* Need to rename InputStream / OutputStream files accordingly.

* AvOutputStream: no sense to create a default outputStream and can't
set its output file or stream index.
* IOutputStream: remove default constructor (automatically generated).

* AvInputStream: no sense to create a default inputStream and can't set
its input file or stream index.
* IInputStream: remove default constructor (automatically generated).

Add prefix "I" for "interface".

According to the name of the class contains in the file.

Contains specific files concern by the binding in general: avException
and avExport.

Contains files concern by the FFmpeg / libav options.

Give the same name as the included class.

LowerCamelCase for file with a list of classes or functions.

We do not want the user to redefine in a derived class the basic
functions to manipulate DataBuffer.

* Also remove default constructor (automatically generated).

* Also rename attributes and local variables about dummy:
     * Transcoder.
     * StreamTranscoder.

* Print a warning if avplay app can't be built.
* Allow the user to build avTranscoder library even if dependencies of
this app are not found.
* fix avTranscoder#94

* Base class of all possible Progress.
* ProgressListener inherits this base class.
* Add documentation.
* Swig: add feature "director" to the base class.

the class implements the IProgress, to display a progress bar in
console.

* Manage cases when we need an IProgress but don't care of a progress
bar.
* Use it in avMeta app: we want the file infos, but don't care of the
progress bar.

* Create ProgressListener.cpp.
* Add include to iostream in Transcoder.

* Contains all files related to the progress.
* Also contains corresponding swig interface file.

Conflicts:

	src/AvTranscoder/file/InputFile.hpp

* 3 classes / files: IProgress, ConsoleProgress, NoDisplayProgress.
* Add a cpp file just for ConsoleProgress (the implementation is more
'complicated' than the others).
