Russ Cox add1ee0ed5 [release-branch.go1.4] runtime: fix SIGPROF change
CL 2789 backported a change that required a barrage of followup CLs.
This CL backports all the followup CLs together.

There are manual edits to os_plan9.go and syscall_windows.go to take
the place of edits to defs_windows_{amd64,386}.go and os2_plan9.go
in the original. Those files do not exist in the release branch, but the
definition being added must go somewhere.

Original change descriptions below.

runtime/cgo: initialize our pthread_create wrapper earlier on openbsd

This is a genuine bug exposed by our test for issue 9456: our wrapper
for pthread_create is not initialized until we initialize cgo itself,
but it is possible that a static constructor could call pthread_create,
and in that case, it will be calling a nil function pointer.

Fix that by also initializing the sys_pthread_create function pointer
inside our pthread_create wrapper function, and use a pthread_once to
make sure it is only initialized once.

Fix build for openbsd.

runtime/cgo: remove unused variable

I missed this one in golang.org/cl/2232 and only tested the patch
on openbsd/amd64.

runtime: skip TestCgoExternalThreadSIGPROF on OS X 10.6

The test program requires static constructor, which in turn needs
external linking to work, but external linking never works on 10.6.

This should fix the darwin-{386,amd64} builders.

runtime: fix TestCgoExternalThreadSIGPROF again

Shell out to `uname -r` this time, so that the test will compile
even if the platform doesn't have syscall.Sysctl.

README

This is the source code repository for the Go programming language.  

For documentation about how to install and use Go,
visit http://golang.org/ or load doc/install-source.html
in your web browser.

After installing Go, you can view a nicely formatted
doc/install-source.html by running godoc --http=:6060
and then visiting http://localhost:6060/doc/install/source.

Unless otherwise noted, the Go source files are distributed
under the BSD-style license found in the LICENSE file.

Binary Distribution Notes

If you have just untarred a binary Go distribution, you need to set
the environment variable $GOROOT to the full path of the go
directory (the one containing this README).  You can omit the
variable if you unpack it into /usr/local/go, or if you rebuild
from sources by running all.bash (see doc/install.html).
You should also add the Go binary directory $GOROOT/bin
to your shell's path.

For example, if you extracted the tar file into $HOME/go, you might
put the following in your .profile:

    export GOROOT=$HOME/go
    export PATH=$PATH:$GOROOT/bin

See doc/install.html for more details.
