I had rewrote functions extract_avp and generate_avps of modules auth_radius, misc_radius and peering, and generate_avps_rad of misc_radius. Now this modules reading, parsing and creating AVPs for any retrieved from RADIUS attributes.

modules parsing SIP-AVP (#int#int, str:str, str#int, #int:str) and not SIP-AVP (#int#int, str:str, str#int, #int:str).

It`s not very well tested, but all my test are passed.

Please review and accept my pull request:

Thanks to Ltd. "Skytel-Systems", Belarus, Minsk and klistrod! It well be impossible without them! :)
