LookupPort() correctly parses service names beginning with numerals by
implementing a new parser, mainly taken from strconv/atoi.go.
Also testes some previously undefined behaviours around port numbers
larger than 65535 that previously could lead to some tests fail with
EOPNOTSUPP (Operation Not Supported).
Fixes#14322

This change makes Dial, Listen and ListenPacket with invalid port fail
whatever GODEBUG=netdns is.
Please be informed that cgoLookupPort with an out of range literal
number may return either the lower or upper bound value, 0 or 65535,
with no error on some platform.

This worked in Go 1.4 but was lost in the "pure Go" lookup
routines substituted late in the Go 1.5 cycle.

This change simplifies unnecessarily redundant error messages in tests.
There's no need to worry any more because package APIs now return
consistent, self-descriptive error values.
Alos renames ambiguous test functions and makes use of test tables.
