Simplify dns_dispatchmgr_create with fixed buffersize

Browse Source 
- UDP buffersize is now established when creating dispatch manager
  and is always set to 4096.

- Set up the default port range in dispatchmgr before setting the magic
  number.

- Magic is not set until dispatchmgr is fully created.
