Allows asterisk to nativly read mp3 files without the need for a codec.  (it produces SLNR streams)


Pure raw SLNR audio.


Reads and writes base64 encoded wav_gsm files (aka wav49)

All this thanks to anthm and asterlink.com

After consulation with anthm on IRC, proceeded as follows:

Added format_sln to Asterisk
Added format_mp3 to asterisk-addons since it's LGPL and would pollute the asterisk license
The conversion to/from base64 will be put in utils.c for general use, rather than being implemented as a file format.

LGPL is compatible with the dual lic since it does allow you to make comercial versions.  If this was the case then all the unixodbc code must be ripped out also.  This was the main reason we went unixODBC is because of the LGPL that does allow you to do exactly this.

a quote from the unixODBC site as an example:

"The LGPL on libs will ensure that commercial solutions will be able to utilize unixODBC."
