When running an experimental kernel with IPv4 disabled, Listen(":port")
currently tries to create an AF_INET socket, and fails. Instead, it
should see !supportsIPv4, and use an AF_INET6 socket.
This sort of environment is quite esoteric at the moment, but I can
force the tests to fail on regular Linux using the following tweaks:
- net/net.go: supportsIPv4, supportsIPv6, supportsIPv4map = false, true, false
- net/sockopt_linux.go: ipv6only=true
- net/ipsock_posix.go: Revert this fix
- ./make.bash && ../bin/go test net
Also, make the arrows in server_test.go point to the left, because
server<-client is easier to read.
Fixes#12510

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.

This change replaces server tests with new ones that require features
introduced after go1 release, such as runtime-integrated network poller,
Dialer, etc.

This change consolidates test helpers that test platform capabilities.
testNetwork, testAddress and testListenArgs report whether given
ariguments are testable on the current platform configuration to
mitigate to receive weird test results.
