[Serusers] New bugfix version of radiusclient library (0.4.2)

[Maxim Sobolev]

Hi,

I've just released the 0.4.2 version of radiusclient library. Main 
changes since 0.4.1 include:

- Some changes from Debian have been merged in (suggested by Sergei
   Golod <rover at tob.ru>):

  + IPv6 attributes added into generic dictionary and radiusclient.h;

  + fixed a bug preventing from using more than one Radius server in
    fall-back scenario.

- Restored historoc behaviour when in the absence of explicit bindaddr
   option in the config file operating system is trusted to assign source
   IP address to outgoing UDP packets according to its routing table.
   Previously in 0.4.x series address rerutned by gethostbyhane(hostname())
   was forced as source IP address for all outgoing UDP packets. The same
   behaviour can be ontained by specifying `bindaddr: *'
   (Problem reported by Juha Heinanen <jh at tutpro.com>, patch by sobomax).

- Added new API function: rc_avpair_log, which allows to create
   pretty-print representation of full radius request or response
   (sobomax).

- Extended dictionary parser so that now it is possible to use comments
   at the end of the configuration lines (Jan Janak <jan at iptel.org>).

The new version is 100% API/ABI compatible with the old one. It can be 
downloaded at

As usually bug reports and suggestions are highly appreciated.

Enjoy!
