Only one use of stringsCompare is left. Cannot simply be replaced by
strings.Compare for bootstrapping reasons I guess.
Moving the function away from util.go to the actual destination data.go
also would not help much. So I left this one unchanged for readability and convenience.

The usage message says:
test [-c] [-i] [build and test flags] [packages] [flags for test binary]
but this was not what was implemented. Instead, after packages are named,
flag processing continues, which makes it impossible, for example, to pass
to the binary a flag with the same name as a test flag. This was triggered
by the -v flag in glog.
Consider this test:
package pkg
... imports ...
var v = flag.Int("v", 0, "v flag")
func TestFoo(t *testing.T) {
if *v != 7 { log.Fatal(*v) }
}
Attempting to run this test with go test pkg -v=7 would give a usage
message. This change allows it. In fact it allows
go test -v pkg -v=7
The solution is to implement the usage message. One compatibility
issue is that flags after the package name are no longer processed
as test flags, so this no longer works:
go test foo -cover
One must write
go test -cover foo
I do not think this is onerous but it must be called out in the
release notes.

Aeshash currently computes the hash of the empty string as
hash("", seed) = seed. This is bad because the hash of a compound
object with empty strings in it doesn't include information about
where those empty strings were. For instance [2]string{"", "foo"}
and [2]string{"foo", ""} might get the same hash.
Fix this by returning a scrambled seed instead of the seed itself.
With this fix, we can remove the scrambling done by the generated
array hash routines.
The test also rejects hash("", seed) = 0, if we ever thought
it would be a good idea to try that.
The fallback hash is already OK in this regard.
