To avoid breaking URLs, we redirect /src/pkg/* to /src/*.
The URL /pkg is now the "directory" /src, which triggers the
"Packages" index.
All other references to "src/pkg" are now gone,
except a number in the namespace documentation which are
probably still illustrative.
Tested: go test cmd/godoc godoc
Manual inspection of src and src/pkg pages.
with GOROOT and GOPATH packages
-analysis
/AUTHORS file URL still works

It was not enough to make /ref/spec work (which it now does),
because some of the docs on golang.org (in particular golang.org/doc)
are pulled from tip, and tip links to /doc/spec now.
Make those "too new" links work by redirecting /doc/spec
back to /ref/spec for now.
