Gotest tries to build things, for which it invokes make,
and it was too hard to coordinate go invoking gotest
invoking go to build the test binary, so put all the code
here instead.  Gotest will be deleted once we switch.

The only code that really made sense to copy verbatim
was the flag parsing.

This remains a work in progress.  There are still plenty
of things to clean up and make better, but this is a good
checkpoint.  It can run all the tests in the tree (except
runtime, which it can't build yet).

In 'go test' I deleted the leading package. prefix
from all the test names, since it contained no actual
information.  Adjust the -test.run argument accordingly.
This will still work with the current gotest too, since
the argument is an unanchored pattern.

An example for a method M() of type T can be written as
func ExampleT_M() { ... }.
To differentiate between multiple examples for one function, type or
method a suffix with a lowercase start may be appended to the name
of the example function, e.g. ExampleFoo_basicUsage.

I'll let the test suite smoke it out.

In some rare cases, gofmt would accept more than the maximum
number of empty lines (1) between source code snippets.

The actual change is in printer.go, lines 773-775; the rest
is some minor restructuring.

If a Pipe method is called, return the underlying
reader/writer from session.clientChan, bypassing the
io.Copy and io.Pipe harness.

StdoutPipe and StderrPipe now return an io.Reader not
an io.ReadCloser as SSH cannot signal the close of the
local reader to the remote process.

Before/after, best of 3:
json.BenchmarkCodeEncoder  10  183495300 ns/op  10.58 MB/s
->
json.BenchmarkCodeEncoder  10  133025100 ns/op  14.59 MB/s

But don't get too excited about this.  These benchmarks, while
stable at any point of time, fluctuate wildly with any line of
code added or removed anywhere in the path due to stack splitting
issues.

It's currently much faster, though, and this is the API that
doesn't allocate so should always be faster in theory.

The plan is to make 'go test' replace gotest entirely, so it
cannot refer to gotest's godoc.  Instead, copy gotest's
documentation in as three different help messages:
'go help test', 'go help testflag', and 'go help testfunc'.

I have included a few important microbenchmarks,
but the overall intent is to have mostly end-to-end
benchmarks timing real world operations.

The jsondata.go file is a summary of agl's
activity in various open source repositories.
It gets used as test data for many of the benchmarks.

Everything links into one binary (even the test data)
so that it is easy to run the benchmarks on many
computers: there is just one file to copy around.

clean is gone; all the intermediate files are created
in a temporary tree that is wiped when the command ends.

Not using go/build's Script because it is not well aligned
with this API.  The various builder methods are copied from
go/build and adapted.  Probably once we delete goinstall
we can delete the Script API too.
