See bug for more details on exactly what was migrated.
Notably:
* No more Google-internal deployment scripts; see README.godoc-app and
the Makefile for details.
* Build tag "golangorg" is used for the godoc configuration used for
golang.org.
* Use of App Engine libraries replaced with GCP client libraries.
* Redis is used to replace App Engine memcache.
* Google analytics is controlled by an environment variable.
* Regression tests have been migrated from Google-internal.
* hg -> git hash map is moved from Google-internal.
Updates golang/go#27205.

Remove all of the code generation and the concept of "APPDIR" - just
generate godoc.zip and index files in the app directory.
Simplify generation of the zip - use a symlink so that every file in
godoc.zip is under the "goroot" directory, regardless of the
environment. Previously, the prefix would be dependent on the location
of the user's GOROOT.
Running the setup script is now optional - it's now possible to run
dev_appserver.py on a regular checkout of cmd/godoc without godoc.zip
and search index files. Use environment variables to switch whether the
zip file is used vs reading GOROOT from the filesystem.
