This CL revises existing platform-dependent default socket
options to make it possible to accomodate multiple multicast
datagram listeners on a single service port.
Also removes unnecessary SO_REUSEADDR, SO_REUSEPORT socket
options from unicast datagram sockets by default.
Fixes#1692.

For now a pair of socket options SOL_SOCKET and SO_BINDTODEVICE
is supported on Linux only. I'd like to demote BindToDevice API
to syscall level because it's Linux dependent one.
In the near future, probably we may have a bit more portable
API that using IPROTO_IP/IPV6 level socket options to specify,
identify an inbound, outbound IP interface on incoming, outgoing
UDP and raw IP packets.

The go/build package already recognizes
system-specific file names like
mycode_darwin.go
mycode_darwin_386.go
mycode_386.s
However, it is also common to write files that
apply to multiple architectures, so a recent CL added
to go/build the ability to process comments
listing a set of conditions for building. For example:
// +build darwin freebsd openbsd/386
says that this file should be compiled only on
OS X, FreeBSD, or 32-bit x86 OpenBSD systems.
These conventions are not yet documented
(hence this long CL description).
This CL adds build comments to the multi-system
files in the core library, a step toward making it
possible to use go/build to build them.
With this change go/build can handle crypto/rand,
exec, net, path/filepath, os/user, and time.
os and syscall need additional adjustments.

This CL changes both JoinGroup and LeaveGroup methods
to take an interface as an argument for enabling IPv6
group address join/leave, join a group address on a
specific interface.

All tests enabled by default passes except those in timeout_test.go.
For TestLookupPort, add an entry for "bootps" in /lib/ndb/common
(Plan 9 calls it "bootp"). I've sent out a patch to fix this.
