checking and two test cases for now.

I am not sure why RunTests and RunExamples are
exported, but I assume that because they are we
should not change the signature, so I added an
unexported global shared by Main and RunTests.

If it didn't reach the limit, we can try extending the arena

kernel to be kind.

This change is necessary to make the run shell script work
again, but it is not sufficient as bug424.go's execution line
does not name the package that it imports.

Allows the Windows part of CL 5700087 to land.

I had build tested CL 5753060 (which allows
crypto/x509 to use cgo and io/ioutil), and
didn't spot any errors on Windows.

Turns out I was wrong.

This moves the various CA root fetchers from crypto/tls into crypto/x509.

The move was brought about by issue 2997. Windows doesn't ship with all
its root certificates, but will instead download them as-needed when using
CryptoAPI for certificate verification.

This CL changes crypto/x509 to verify a certificate using the system root
CAs when VerifyOptions.RootCAs == nil. On Windows, this verification is
now implemented using Windows's CryptoAPI. All other root fetchers are
unchanged, and still use Go's own verification code.

The CL also fixes the hostname matching logic in crypto/tls/tls.go, in
order to be able to test whether hostname mismatches are honored by the
Windows verification code.

The move to crypto/x509 also allows other packages to use the OS-provided
root certificates, instead of hiding them inside the crypto/tls package.

Fixes #2997.

The compiler must be changed with the Set method
so that the buildToolchain gets updated too.

The old way to find a port was to listen :0 and then
look at what port it picked, close the listener, and then
immediately try to listen on that port.

On some Windows 7 machines that sequence fails at
the second listen, because the first one is still lingering
in the TCP/IP stack somewhere.  (Ironically, most of these
are used in tests of a "second listen", which in this case
ends up being the third listen.)

Instead of this race, just return the listener from the
function, replacing usableLocalPort+Listen with
usableListenPort.

Fixes #3219.

I don't know what's out there, but something
is answering to 127.0.71.111:80 on our builder,
so use a different port.

Also insert a check that the dial fails, which
would have diagnosed this problem.
