thread_GOOS.c becomes os_GOOS.c.
signal_GOOS_GOARCH.c becomes os_GOOS_GOARCH.c,
but with non-GOARCH-specific code moved into os_GOOS.c.
The actual arch-specific signal handler moves into signal_GOARCH.c
to avoid per-GOOS duplication.
New files signal_GOOS_GOARCH.h provide macros for
accessing fields of the very system-specific signal info structs.
Lots moving, but nothing changing.
This is a preliminarly cleanup so I can work on the signal
handling code to fix some open issues without having to
make each change 13 times.
Tested on Linux and OS X, 386 and amd64.
Will fix Plan 9, Windows, and ARM after the fact if necessary.
(Plan 9 and Windows should be fine; ARM will probably have some typos.)
Net effect: -1081 lines of code.

An earlier CL disallowed ~ anywhere in GOPATH, to avoid
problems with GOPATH='~/home' instead of GOPATH=~/home.
But ~ is only special in the shell at the beginning of each of
the paths in the list, and some paths do have ~ in the middle.
So relax the requirement slightly.

The new build tag "go1.1" will be satisfied by any Go 1.z release >= 1.1.
In general, the build tag "go1.x" will be satisfied by any Go 1.z release >= 1.x.
What happens when we reach Go 2 is yet to be decided.
The tags "go1" or "go1.0" are missing, because +build tags did not exist
before then, and also because the Go 1.0 releases do not recognize them.
The new -installsuffix flag gives access to the build context's InstallSuffix
(formerly named InstallTag, but not part of Go 1.0), for use in isolating
builds to custom directories. For example -race implies -installsuffix race,
and an AppEngine-specific build might use -tags appengine -installsuffix appengine.

valgrind complained that under some circumstances,
*nr = *nc
was being called when nr and nc were the same *Node. The suggestion my Rémy was to introduce a tmp node to avoid the potential for aliasing in subnode.

If a fixed size array is passed in as the decode target and the JSON
to decode has extra array elements that are objects, then previously
the decoder would return a "data changing underfoot" error.

Correctly indent the body of functions that have been declared
over multiple lines. See http://play.golang.org/p/MHMwNDbFyf for
an example.
Previously, the body of the function would be indented as deep as
the continuation line of the function declaration. Now it gets
indented as deep as the func keyword.

Fixes#4705.
Note that libjpeg will print a warning to stderr if there are many
extraneous bytes, but can be silent if the extraneous bytes can fit
into its int32 bit-buffer for Huffman decoding. I'm guessing that
this is why whatever encoder that produced the image filed for issue
4705 did not realize that they are, strictly speaking, generating an
invalid JPEG. That issue's attached image has two extraneous bytes.
For example, piping the program below into libjpeg's djpeg program
will print an "18 extraneous bytes" warning, even though N == 20.
$ cat main.go
package main
import (
"bytes"
"image"
"image/color"
"image/jpeg"
"os"
)
const N = 20
func main() {
// Encode a 1x1 red image.
m := image.NewRGBA(image.Rect(0, 0, 1, 1))
m.Set(0, 0, color.RGBA{255, 0, 0, 255})
buf := new(bytes.Buffer)
jpeg.Encode(buf, m, nil)
b := buf.Bytes()
// Strip the final "\xff\xd9" EOI marker.
b = b[:len(b)-2]
// Append N dummy 0x80 bytes to the SOS data.
for i := 0; i < N; i++ {
b = append(b, 0x80)
}
// Put back the "\xff\xd9" EOI marker.
b = append(b, 0xff, 0xd9)
os.Stdout.Write(b)
}
$ go run main.go | djpeg /dev/stdin > /tmp/foo.pnm
Corrupt JPEG data: 18 extraneous bytes before marker 0xd9
The resultant /tmp/foo.pnm is a perfectly good 1x1 red image.

The parameter list layout function was incorrectly computing the
end of the previous line in cases where a parameter type spanned

comma was introduced before the paremeter list's closing parenthesis.
