  Log Message:
  -----------
  In UAS replies, preserve the CSEQ from the UAS request

Instead of computing the cseq for the forwarded replied, better use the cseq value from the original requests (like restoring).
Thanks to @razvancrainea for the brainstorming on the issue.

Fixes #1969

  Log Message:
  -----------
  Fix computing the cseq for a branch.

Instead of assuming a +1 increment (to the cseq from request), better copy the cseq from the received reply.
Thanks to @razvancrainea for the brainstorming.
