Fix SRV lookup and Request-URI generation in chan_sip.

Browse Source 
This patch adds a new field "portinuri" to the sip dialog struct and the sip peer struct.  That field is used during RURI generation to determine if the port should be included in the RURI.  It is also used in some places to determine if an SRV lookup should occur.

(closes issue #14418)
