small changes for portability and diff reduction wrt/ FreeBSD 7.
No functional differences.

- use the div64() macro to wrap 64 bit divisions
  (which almost always are 64 / 32 bits) so they are easier
  to handle with compilers or OS that do not have native
  support for 64bit divisions;

- use a local variable for p_numbytes even if not strictly
  necessary on HEAD, as it reduces diffs with FreeBSD7

- in dummynet_send() check that a tag is present before
  dereferencing the pointer.

- add a couple of blank lines for readability near the end of a function

MFC after:	3 days
