There's currently a bug which will print additional lines, since append adds to
the end of an array instead of starting from the first open position. That cause
strings.Join to print empty lines for each of the pre-allocated array elements.
So, this CL changes the make to set capacity instead of len, and sets len to 0.

When the GOMOD value is the operating system's null device, there
isn't a main module and thus there cannot be module requirements.
Don't try to fill module cache, since running 'go mod download'
would cause a "no modules specified (see 'go help mod download')"
error to be printed, which is confusing.

This change implements initial support for viewing Go package
documentation with godoc in module mode. There are no UI changes.
When running the godoc binary in a directory where module mode
is active (i.e., go env GOMOD reports a non-empty path), the
documentation will be shown for packages provided by modules
rather than from the GOPATH workspace.
The mode can be controlled in the same way as the go command, by
changing the GO111MODULE environment variable¹ value. For example,
'GO111MODULE=on godoc' will force godoc to run in module mode, and
'GO111MODULE=off godoc' will force godoc to run in GOPATH mode.
It is implemented by reusing the existing virtual filesystem
abstraction. The main module and all of its dependencies (in
other words, the build list²) are determined by invoking the
go list -m all command in the same directory. An attempt is
made to fill the module cache with any selected module versions
that are not already in the local module cache.
This behavior can be controlled in the same way as the go command,
by setting the GOPROXY environment variable. For example, setting
GOPROXY=off disables downloading of any modules. If any of the
modules could not be fetched, it is printed to stderr and
documentation is shown for all other available packages.

This change replaces the env package with a new golangorgenv package.
The previous env package existed primarily to configure the godoc
instance that was running golang.org. By now, the golang.org website
has been factored out to x/website, which has its own env package,
but ends up still using this env package indirectly via x/tools/godoc.
The goal of this change is to make env available for other services
that run on subdomains of golang.org, so they can continue to safely
rely on the x/tools/playground, which will be modified in the next
commit to also use the new golangorgenv.
The golangorgenv package replaces the IsProd function with a more
specific one. Start using it in packages x/tools/{,cmd}/godoc. Also,
re-arrange the order of checks to give the host suffix check higher
priority than the environment variable check. This way, if the
environment variable isn't set, the host suffix check gets a chance
to run.
When getting the value of "X-AppEngine-Country" header, use its
canonical format "X-Appengine-Country" to avoid an allocation.
