New Revision: 36170

URL: http://svn.digium.com/view/asterisk?rev=36170&view=rev
Log:
- Set the SIP_OUTGOING flag *only* for a dialog - was it outbound or inbound when it was created
- Add a flag for the last TRANSACTION to see if it's outbound or inbound
  We can send re-invites on OUTBOUND and INBOUND calls, but re-invites should
  not change the direction of the call
  We can receive re-invites in the same way
- Now, we need the new flag to pick correct from/to headers and tags, which is a current bug
  that affects both normal calls and t.38 re-invites.

This is not the complete fix, but a start of this branch in order to fix these issues with
svn trunk
