New siproxd release 0.8.0

This release fixes CVE-2009-3736, includes a better handling of symmetric RTP 
and provides support for the UPDATE method. Everybody, please move ahead to this 
version.

CVE-2009-3736: Local privilege escalation:
Siproxd does include a so called convenience copy of libldtl. Recently a 
local privilege escalation issue has been found and reported:

"ltdl.c in libltdl in GNU Libtool 1.5.x, and 2.2.6 before 2.2.6b, attempts 
to open a .la file in the current working directory, which allows local users 
to gain privileges via a Trojan horse file."

Two measures have been implemented with siproxd:
- Siproxd does use a system provided libltdl, if available. The included 
convenienve copy will only be used as a fallback if no libltdl is provided 
on the building host.
- The included convenience copy in the siproxd package has been updated to 
a version that has this issue fixed.
