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.
This does not change behavior.

It's possible to use a type which implements fmt.Formatter without
importing fmt directly, if the type is imported from another package
such as math/big.
On top of that, it's possible to use printf-like functions without
importing fmt directly, such as using testing.T.Logf.
These two scenarios combined can lead to the printf check not finding
the fmt.Formatter type, since it's not a direct dependency of the root
package.
fmt must still be in the import graph somewhere, so we could search for
it via types.Package.Imports. However, at that point it's simpler to
just look for the Format method manually via go/types.

This CL is based on the work and discussion in CL 24969 and CL 32392.
It simplifies the code further and makes trybots pass on Windows.
Also update the documentation and implementation of the subpackages
function slightly to make it more clear what it's doing.
Background
CL 24943 has made progress on fixing rename.Move behavior on Windows,
but hadn't re-enabled TestMoves at the time. CL 24969 attempted to do
so, but the tests weren't passing and it didn't get merged at the time.
Since that time, CL 65672 has fixed a bug in the subpackages function.
As a result, it's possible to simplify code in Move now.
The subpackages function returns a set of packages in the given srcDir
whose import path equals to root or has "root/" as the prefix.
After CL 65672, it correctly filters out ones that are not true
sub-packages of root. That's why it's not necessary to try to append
a trailing separator when doing the string replacement in Move now.
Given subpackages reports their import paths (always '/'-separated),
not filesystem paths, it's not necessary to use filepath.ToSlash either.
