aa0dda767a net: support IPv6 scoped addressing zone
This CL provides IPv6 scoped addressing zone support as defined
in RFC 4007 for internet protocol family connection setups.

Follwoing types and functions allow a literal IPv6 address with
zone identifer as theirs parameter.

pkg net, func Dial(string, string) (Conn, error)
pkg net, func DialOpt(string, ...DialOption) (Conn, error)
pkg net, func DialTimeout(string, string, time.Duration) (Conn, error)
pkg net, func Listen(string, string) (Listener, error)
pkg net, func ListenPacket(string, string) (PacketConn, error)
pkg net, func ResolveIPAddr(string, string) (*IPAddr, error)
pkg net, func ResolveTCPAddr(string, string) (*TCPAddr, error)
pkg net, func ResolveUDPAddr(string, string) (*UDPAddr, error)
pkg net, type IPAddr struct, Zone string
pkg net, type TCPAddr struct, Zone string
pkg net, type UDPAddr struct, Zone string

Also follwoing methods return a literal IPv6 address with zone
identifier string if possible.

pkg net, method (*IPAddr) String() string
pkg net, method (*TCPAddr) String() string
pkg net, method (*UDPAddr) String() string

Fixes #4234.
Fixes #4501.
Update #5081.

2) Manual adjustments to the following files under src/pkg:
   gob/decode.go
   rpc/client.go
   os/error.go
   io/io.go
   bufio/bufio.go
   http/request.go

c9164a5d77 net: use C library resolver on FreeBSD, Linux, OS X / amd64, 386
This CL makes it possible to resolve DNS names on OS X
without offending the Application-Level Firewall.

It also means that cross-compiling from one operating
system to another is no longer possible when using
package net, because cgo needs to be able to sniff around
the local C libraries.  We could special-case this one use
and check in generated files, but it seems more trouble
than it's worth.  Cross compiling is dead anyway.

It is still possible to use either GOARCH=amd64 or GOARCH=386
on typical Linux and OS X x86 systems.

It is also still possible to build GOOS=linux GOARCH=arm on
any system, because arm is for now excluded from this change
(there is no cgo for arm yet).

41f93a430f net: drop laddr from Dial, cname from LookupHost; new functions
Drop laddr argument from Dial.

Drop cname return from LookupHost.

Add LookupIP, LookupCNAME, ParseCIDR, IP.Equal.
Export SplitHostPort, JoinHostPort.
Add AAAA (IPv6) support to host lookups.

Preparations for implementing some of the
lookups using cgo.

ParseCIDR and IP.Equal are logically new in this CL
but accidentally snuck into an earlier CL about unused
labels that was in the same client.

In crypto/tls, drop laddr from Dial to match net.

0856731daa net: add IPv4 multicast to UDPConn
notes:
Darwin is very particular about joining a multicast group if the
listneing socket is not created in "udp4" mode, the other supported
OS's are more flexible.

A simple example sets up a socket to listen on the mdns/bonjour
group 224.0.0.251:5353

// ensure the sock is udp4, and the IP is a 4 byte IPv4
socket, err := net.ListenUDP("udp4", &net.UDPAddr {
        IP: net.IPv4zero,
        // currently darwin will not allow you to bind to
        // a port if it is already bound to another process
        Port: 5353,
})
if err != nil {
        log.Exitf("listen %s", err)
}
defer socket.Close()
err = socket.JoinGroup(net.IPv4(224, 0, 0, 251))
if err != nil {
        log.Exitf("join group %s", err)
}

47a0533411 net: introduce net.Error interface
Adds two more methods, Timeout and Temporary.
Implemented by os.Errno too.  The intent is to make
the checks for os.EAGAIN a little less clunky.
It should also let us clean up a bug that Mike Solomon
pointed out: if a network server gets an "out of file descriptors"
error from Accept, the listener should not stop.
It will be able to check this because that error would
have Temporary() == true.

Also clean up some underscore names.

Fixes #442.

a3d1045fb7 1) Change default gofmt default settings for
parsing and printing to new syntax.

   Use -oldparser to parse the old syntax,
   use -oldprinter to print the old syntax.

2) Change default gofmt formatting settings
   to use tabs for indentation only and to use
   spaces for alignment. This will make the code
   alignment insensitive to an editor's tabwidth.

   Use -spaces=false to use tabs for alignment.

3) Manually changed src/exp/parser/parser_test.go
   so that it doesn't try to parse the parser's
   source files using the old syntax (they have
   new syntax now).

4) gofmt -w src misc test/bench

c83b838641 package net cleanup
added ReadFrom/WriteTo for packet protocols like UDP.
simplified the net.Conn interface.
added new net.PacketConn interface for packet protocols.
implemented proper UDP listener.

cleaned up LocalAddr/RemoteAddr methods - cache in netFD.

threw away various unused methods.

an interface change:
introduced net.Addr as a network address interface,
to avoid conversion of UDP host:port to string and
back for every ReadFrom/WriteTo sequence.

another interface change:
since signature of Listener.Accept was changing anyway,
dropped the middle return value, because it is available
as c.RemoteAddr().  (the Accept signature predates the
existence of that method.)

Dial and Listen still accept strings, but the proto-specific
versions DialTCP, ListenUDP, etc. take net.Addr instead.

because the generic Dial didn't change and because
no one calls Accept directly (only indirectly via the http
server), very little code will be affected by these interface
changes.

design comments welcome.
