This is a followup to CL 199840 and CL 203820. Cumulatively, they caused
a previously known bug to trigger more often while also nearly fixing it.
This change is a small fixup to CL 199840 that resolves the known bug
and prevents it from causing an additional regression in Go 1.14.
Part 1
The intention in CL 199840 was to return the same error that 'go list'
reported when the package wasn't located, so an early return was added.
However, to determine whether the package was located or not, p.Dir was
unintentionally checked instead of dir.
p is initialized to &Package{ImportPath: path} at top of Context.Import,
and its Dir field is never set before that line in importGo is reached.
So return errors.New(errStr) was always executed whenever errStr != "".
Originally, in CL 125296, the "go list" invocation did not include an
'-e' flag, so it would return a non-zero exit code on packages where
build constraints exclude all Go files, and importGo would return an
error like "go/build: importGo import/path: unexpected output: ...".
CL 199840 added an '-e' flag to the "go list" invocation, but checking
the wrong dir variable caused partial package information to never get
populated, and thus issue #31603 continued to occur, although with a
different error message (which ironically included the location of the
package that was supposedly "not found").
Now that the right dir is checked, issue #31603 is fixed.
Part 2
importGo checks whether it can use the go command to find the directory
of a package. In Go 1.13.x and earlier, one of the conditions to use the
go command was that the source directory must be provided.
CL 203820 made a change such that knowing the source directory was
no longer required:
// To invoke the go command,
-// we must know the source directory,
// ...
That meant build.Import invocations where srcDir is the empty string:
build.Import(path, "", build.FindOnly)
Started using the go command to find the directory of the package, and
started to run into issue #31603 as well. That's the #37153 regression.
Since this change fixes issue #31603, it also fixes issue #37153.
Part 3
There is one more thing. Delete the debugImportGo constant, it's unused.

The most well known and important build constraints to take into
account when rendering package documentation are the GOOS/GOARCH
values. Make it more clear in the NewFromFiles documentation that
they are a part of all build constraints that the caller is
responsible for filtering out.
Also suggest the "go/build".Context.MatchFile method for performing
file matching. The logic to perform build context file matching is
subtle and has many rules that aren't well known (for example,
taking the gc or gccgo compiler into account). It is currently the
only exported API in the standard library that implements this logic,
and it would be unfortunate if people attempt to re-create it because
they don't realize it is already available.

HTML pages served by the website have the option to opt-in to template
processing, by including "Template: true" in the page metadata.
This functionality is documented at
403f1254bd/godoc/template.go (L5-L30).
Historically, the Go 1 release notes have used template processing
to a great extent, but release notes for all subsequent major Go
releases have not.
Since this feature is generally not used and not very well known,
it tends to do more harm than good by making it possible for errors
in the template to prevent the release notes from showing up at all.
Disable this feature for Go 1.14 release notes and onwards.
We can consider enabling it when there's a stronger need for it.

In CL 199417, we updated “How to Write Go Code” to give a basic
introduction to modules and to include module-mode commands.
However, most new users will end up reading “Getting Started”
(doc/install.html) before “How to Write Go Code”, and we forgot to
update the handful of commands there for module mode.
Before this change, the “Test your installation” section also covered
quite a few operations beoyond merely testing the installation: it
included setting up a GOPATH, building a binary, and installing and
cleaning binaries. Those are valuable operations to learn, but they
arguably belong in “How to Write Go Code”, not “Test your
installation” — and having all that extra detail in the install
instructions may well discourage folks from further essential reading.
Rather than updating all of those operations here, I've removed them.
A companion CL will update “How to Write Go Code” to ensure that it
mentions GOPATH (as the location of the module cache and the default
install location for binaries) and 'go clean -i'.

It's possible for the scheduler to try to preempt a goroutine running
on a thread created by C code just as the goroutine returns from Go code
to C code. If that happens, the goroutine will have a nil g,
which would normally cause us to enter the badsignal code.
The badsignal code will allocate an M, reset the signal handler,
and raise the signal. This is all wasted work for SIGURG,
as the default behavior is for the kernel to ignore the signal.
It also means that there is a period of time when preemption requests
are ignored, because the signal handler is reset to the default.
And, finally, it triggers a bug on 386 OpenBSD 6.2. So stop doing it.
No test because there is no real change in behavior (other than on OpenBSD),
the new code is just more efficient
