New tests added for port handling and IDNA domains.
A new test case contains several redundant
tests but provides a nice documentation of the
implemented rules for domain handling.

files have a package attached. The tests for pkg.types and pkg.values

Permits all sorts of custom HTTP timeout policies without
adding a new Transport timeout Duration for each combination
of HTTP phases.

This keeps track internally of which TCP connection a given
Request is on, and lets callers forcefully close the TCP
connection for a given request, without actually getting
the net.Conn directly.

Additionally, a future CL will implement res.Body.Close (Issue
3672) in terms of this.

ssadump:
- permit naming a package (not just *.go files) on command line.
- set BuildSerially flag when setting Log* flags
  (Q. should instead the logging functions take a lock?)

Builder:
- fixed bug when calling variadic function with zero '...'-params.
  Added regression test.

interp:
- more external functions:
   the 'error' interface
   bytes.{Equal,IndexByte}
   reflect.(Value).{Bool,NumOut,Out}
   syscall.{Close,Fstat,Read,Open,Stat,Lstat,Fstat,
     Getdents,ParseDirents,Getwd}
- permit comparisons between *Function and *closure.

With this CL, ssadump can now interpret ssadump itself (!),
loading, parsing, typing, SSA-building, and running
println("Hello, World!").  While a fmt-based equivalent still
lacks some external routines, e.g. math/big, I think there are
diminishing returns in expanding the interpreter (and
debugging it is starting to feel like "Inception").

I'm pretty confident this package is now good enough for wider use.

Add DialOpt. So we have:

func Dial(net, addr string) (Conn, error)
func DialTimeout(net, addr string, timeout time.Duration) (Conn, error)
func DialOpt(addr string, opts ...DialOption) (Conn, error)

DialTimeout (and Dial) are regrettable in retrospect. Maybe
in a future Go we'll be back down to one Dial, with DialOpt
becoming Dial.

DialOpt looks like:

c, err := net.DialOpt("google.com:80")  // tcp is default
c, err := net.DialOpt("google.com:80", net.Timeout(30 * time.Second))
c, err := net.DialOpt("google.com:80", net.TCPFastOpen())
c, err := net.DialOpt("google.com:80", net.LocalAddr(..))
c, err := net.DialOpt("google.com:53", net.Network("udp6"))

And then: (clustered in godoc)

type DialOption interface { /* private only */ }
  func Deadline(time.Time) DialOption
  func LocalAddr(Addr) DialOption
  func Network(string) DialOption
  func TCPFastOpen() DialOption
  func Timeout(time.Duration) DialOption

I'm pretty confident we could add Happy Eyeballs to this too.

The correct semantics of named result parameters and deferred
procedures cannot be implemented with the existing Ret
instruction alone, since the required sequence is:
(1) evaluate return operands and parallel-assign them to
    named result parameters
(2) invoke deferred procedures
(3) load named result parameters to form result tuple.

We introduce a new 'rundefers' instruction that explicitly
invokes the deferred procedure calls, and we generate code
that follows the sequence above.

Most functions do not use deferred procedures but this cannot
be known in a single pass.  So, we add an optimisation to
eliminate redundant 'rundefers'; it is piggybacked on the
existing pass done for "lifting".

Added tests.

The current code uses 64-bit pc-relative on 64-bit systems,
but in ELF linkers there is no such thing, so we cannot
express this in a .o file. Change to 32-bit.

This CL changes the encoding used for the Go symbol table,
stored in the binary and used at run time. It does not change
any of the semantics or structure: the bits are just packed
a little differently.

The comment at the top of runtime/symtab.c describes the new format.

Compared to the Go 1.0 format, the main changes are:

* Store symbol addresses as full-pointer-sized host-endian values.
  (For 6g, this means addresses are 64-bit little-endian.)

* Store other values (frame sizes and so on) varint-encoded.

The second change more than compensates for the first:
for the godoc binary on OS X/amd64, the new symbol table
is 8% smaller than the old symbol table (1,425,668 down from 1,546,276).

This is a required step for allowing the host linker (gcc) to write
the final Go binary, since it will have to fill in the symbol address slots
(so the slots must be host-endian) and on 64-bit systems it may
choose addresses above 4 GB.

Actually it already worked since the spec only requires that
the one immediately preceding a for/switch/... be usable as
the target of a break or continue statement.

The original go-mode is plagued with odd behaviour, lack of
behaviour typical to modes in Emacs and bugs.

This change rewrites great parts of go-mode (basically only
keeping the gofmt and godoc functions).

Additionally it adds new features such as manipulating package
imports.
