  Log Message:
  -----------
  Replace deprecated splitport and splittype.

Python 3.8 deprecates `splitport` and `splittype`, see
https://github.com/python/cpython/blob/master/Lib/urllib/parse.py#L1039-L1042
resp.
https://github.com/python/cpython/blob/master/Lib/urllib/parse.py#L969-L972

VirtualHostMonster.py imports `splitport` from `HTTPRequest`.
It is modelled after the requirements of its tests.

The default ports changed from str to int because `urlparse` returns int port
numbers.
