  RFC3261 Section 8.1.1.5. The sequence number value MUST be expressible as a 32-bit unsigned integer

  * fix: use %u instead of %d when dealing with CSeq numbers - to remove possibility of -ve numbers.

  * fix: change all uses of seqno and friends (ocseq icseq) from 'int' or 'unsigned int' to uint32_t.

  Summary of CSeq numbers.
  An initial CSeq number must be less than 2^31
  A CSeq number can increase in value up to 2^32-1
  An incrementing CSeq number must not wrap around to 0.

  Tested with Asterisk 1.8.8.2 with Grandstream phones.
