Summary: New SIP Session Timer (SST) module

Initial Comment:
The new module gives OpenSER basic SIP Session Timer
support. See rfc4028 for more information on SST. This
new module uses the new dialog module to track the
creation, updating and termination of SIP dialogs. The
dialog module supports timed out termination of the
dialog but at this time the timeout value is hardcoded
(avp accessable and modparam() settable) 

What the sst module does is uses the dialogs own
callbacks to update the dialog timeout value based on
the current expire: header value. 

There is also a script function called
sstCheckMin(min_se_value) that can be used in a proxy
configuration to reply with a 422 "Session Interval Too
 Small" to a INVITE with a small MIN_SE value.

As I see new functionality requirements of the module I
will add it. If you have a request for some new
functionality in the SST module, please email me 
your ideas.

Attached is the second (fixed tar ball) The attached
file is a gzipped tar ball of the sst module directory
tree. (cd openser/modules && tar -xzf sst.tgz to extract)
