further to how (I believe) it will end up being.
It is nicer to separate search from sorting functionality. Collation needs tables that
are not needed by search and vice-versa.  The common functionality is separated out
in the Weigher interface.  As this interface is very low-level, it will be moved to
a sub package (colltab) in a next CL.
The types that will move to this package are Weigher, Elem, and Level.  The addition
of Elem allows for removing some of the duplicate code between collate and collate/build.
This CL also introduces some stubs for a higher-level API for options. The default
proposed options are quite complex and require the user to have a decent understanding
of Unicode collation.  The new options hide a lot of the complexity.

Fixes the fork-exec/wait race condition for ForkExec
as well, by making it use startProcess. This makes the
comment for StartProcess consistent as well.

Further, the passing of Waitmsg data in startProcess
and WaitProcess is protected against possible forks
from outside of ForkExec and StartProcess, which might
cause interference with the Await call.

BenchmarkString before:

        11990 ns/op            1621 B/op         73 allocs/op

Using bytes.Buffer:

        8774 ns/op            1994 B/op         40 allocs/op

I also tried making a version of escape() that writes directly to the
bytes.Buffer, but it only saved 1 alloc/op and increased CPU time by
about 10%. Didn't seem worth the extra code path.

Parse("file:///foo") previously returned a URL with Scheme "file"
and Path "///foo". Now it returns a URL with Path "/foo",
such that
        &URL{Scheme: "file", Path: "/foo"}.String() == "file:///foo"

This means that parsing and stringifying the URL "file:/foo"
returns "file:///foo", technically a regression but one that only
affects a corner case.

This proposal adds two methods to *testing.T, Skip(string) and Skipf(format, args...). The intent is to replace the existing log and return idiom which currently has 97 cases in the standard library. A simple example of Skip would be:

func TestSomethingLong(t *testing.T) {
        if testing.Short() {
                t.Skip("skipping test in short mode.")
                // not reached
        }
        ... time consuming work
}

Additionally tests can be skipped anywhere a *testing.T is present. An example adapted from the go.crypto/ssh/test package would be:

// setup performs some before test action and returns a func()
// which should be defered by the caller for cleanup.
func setup(t *testing.T) func() {
        ...
        cmd := exec.Command("sshd", "-f", configfile, "-i")
        if err := cmd.Run(); err != nil {
                t.Skipf("could not execute mock ssh server: %v", err)
        }
        ...
        return func() {
                // stop subprocess and cleanup
        }
}

func TestDialMockServer(t *testing.T) {
        cleanup := setup(t)
        defer cleanup()
        ...
}

In verbose mode tests that are skipped are now reported as a SKIP, rather than PASS.

Previously, Go TLS servers always took the client's preferences into
account when selecting a ciphersuite. This change adds the option of
using the server's preferences, which can be expressed by setting
tls.Config.CipherSuites.
