This change reverts the following CLs:
	CL/18274: handle mtime in NTFS/UNIX/ExtendedTS extra fields
	CL/30811: only use Extended Timestamp on non-zero MS-DOS timestamps

We are reverting support for extended timestamps since the support was not
not complete. CL/18274 added full support for reading extended timestamp fields
and minimal support for writing them. CL/18274 is incomplete because it made
no changes to the FileHeader struct, so timezone information was lost when
reading and/or writing.

While CL/18274 was a step in the right direction, we should provide full
support for high precision timestamps in both the reader and writer.
This will probably require that we add a new field of type time.Time.
The complete fix is too involved to add in the time remaining for Go 1.8
and will be completed in Go 1.9.

golang.org/issue/17594 was caused by additab being called more than once for
an itab. golang.org/cl/32131 fixed that by making the itabs local symbols,
but that in turn causes golang.org/issue/18252 because now there are now
multiple itab symbols in a process for a given (type,interface) pair and
different code paths can end up referring to different itabs which breaks
lots of reflection stuff. So this makes itabs global again and just takes
care to only call additab once for each itab.

Search the sample types in the profile being processed to map

Previously these were hardcoded, which caused issues when the

format.

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

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.
