I haven't been able to reproduce this one, but change a few suspect
things in this test. Notably, using the global "Get" function and thus
using the DefaultTransport was buggy in a parallel test. Then add some error
checks and close a TCP connection.

Hopefully the failure wasn't timing-related.

Search the sample types in the profile being processed to map
sample type options to indices in the profile sample type array.

Previously these were hardcoded, which caused issues when the
sample types for a profile type changed. For instance, this was
triggered by the native generation of profiles in profile.proto
format.

This fixes #18230. A similar mechanism already exists on the upstream
pprof.

We are seeing a bad stack map in #18190. In a copystack, it is
mistaking a slot for a pointer.

Presumably this is caused either by our fledgling dynlink support on
darwin, or a consequence of having two copies of the runtime in the
process. But I have been unable to work out which in the 1.8 window,
so pushing darwin support to 1.9 or later.

The client code was using time.Now() (wall time) to determine whether
the cause of a non-nil error meant that a timeout had occured. But on
Windows, the clock used for timers (time.After, time.Sleep, etc) is
much more accurate than the time.Now clock, which doesn't update
often.

But it turns out that as of the recent https://golang.org/cl/32478 we
already have the answer available easily. It just wasn't in scope.

Instead of passing this information along by decorating the errors
(risky this late in Go 1.8, especially with #15935 unresolved), just
passing along the "didTimeout" func internally for now. We can remove
that later in Go 1.9 if we overhaul Transport errors.
