This is part one of two changes intended to make it easier to debug builder failures.
runOutput allows us to control the io.Writer passed to a subcommand. The intention is to add additional debugging information before and after the build which will then be capture and sent to the dashboard.
In this proposal, the only additional information is the build status. See http://build.golang.org/log/e7b5bf435b4de1913fc61781b3295fb3f03aeb6e

The dashboard is currently failing to store results of new builds for some keys, notable the go.codereview sub repository. This is causing the builders to mark the entire triggering commit as failed. With the help of David Symonds we think it is because the results value has breached the 1mb datastore limit on AppEngine.

* Separate internal and external LockOSThread, for cgo safety.
* Show goroutine that made faulting cgo call.
* Never start a panic due to a signal caused by a cgo call.

This prevents the occasional issue when Mercurial screws up the locking
itself, and by moving the locking into this process we can use the
goroot for other things (such as automatically updating the builder
binary).
It also asks all builders to poll for new commits.

This proposal updates the dashboard builder to avoid relying on the (soon to be removed) support for using go get to download to $GOROOT. The result is
WORKSPACE=$(the value of the -buildRoot flag / $BUILDER_NAME + hg revision)
GOROOT=$WORKSPACE/go
GOPATH=$WORKSPACE

Enable cgo on OpenBSD.
The OpenBSD ld.so(1) does not currently support PT_TLS sections. Work
around this by fixing up the TCB that has been provided by librthread
and reallocating a TCB with additional space for TLS. Also provide a
wrapper for pthread_create, allowing zeroed TLS to be allocated for
threads created externally to Go.
Joint work with Shenghou Ma (minux).

The "did_ftplugin" lines were ineffective and the "K" mapping was too
invasive, which is why it was removed.

Too many people quote entire emails and put their reply at the top ("top posting"),

In a few places, the existing cgo tests assume that a
Go int is the same as a C int. Making int 64 bits wide
on 64-bit platforms violates this assumption.
Change that code to assume that Go int32 and C int
are the same instead. That's still not great, but it's better,
and I am unaware of any systems we run on where it is not true.

Always process the DWARF info, even when the const value is determined
using the debug data block. This ensures that the injected enum is
removed and future loads of the same constant do not trigger
inconsistent definitions.
Add tests for issues 2470 and 4054.

Previously, an import block such as
import (
"net"
"stack"
)
would not permit ":Drop stack" to work because we were aborting
the scan early, which is only correct when Import is in operation.

Run a background goroutine that wastes CPU to trick the
power management into raising the CPU frequency which,
by side effect, makes sleep more accurate on arm.
