[Serusers] radiusclient new generation, first beta release

[Maxim Sobolev]

New beta release is available, main changes:

- All static storage is removed from the library to make it re-entrant;

- support for VSA attributes added;

- support for $INCLUDE directive in dictionary file added;

- style: remove all typecasts for NULL, convert all return statements to 
a single style.

You can download it here:

Tomorrow I'll post my patches for SER to make it work with new radiusclient.

Enjoy! Let me know if there any bugs or problems with this version.
