Tests: fixed parallel tests execution with UDP.
Previously, when checking ports availability, a UDP socket was always created
first, then a TCP socket was created. On success, one of UDP and TCP sockets
was closed (depending on the "udp" option) and the second one was used to busy
this port in other scripts. This lead to the following problem: in an attempt
to reopen a UDP socket used in a given testing script it could be stolen by
another script as part of checking ports availability.
To solve this problem, UDP and TCP ports were split into two non-overlapping
ranges: TCP ports are only used in the range 8000-8499, and UDP ports - in
the range 8500-8999. In addition, the order of creating sockets in UDP tests
has been reversed: now a TCP socket used as a lock precedes a UDP socket.
