New Revision: 158230

URL: http://svn.digium.com/view/asterisk?view=rev&rev=158230
Log:
Change the remote user agent session version variable
from an int to a uint64_t. This prevents potential comparison
problems from happening if the version string exceeds
INT_MAX. This was an apparent problem for one user who could
not properly place a call on hold since the version in the
SDP of the re-INVITE to place the call on hold greatly 
exceeded INT_MAX.

This also aligns with RFC 2327 better since it recommends
using an NTP timestamp for the version (which is a 
64-bit number).
