Notably: pkg/misc all moves.
And pkg/googlestorage is deleted, since it's not used. Only the
x/net/http2/h2demo code used to use it, but that ended in
https://go-review.googlesource.com/33230 (our vendored code is old).
So just nuke that dir for now. When it's refreshed, it'll either be
gone (dep prune) or new enough to not need googlestorage.
Also move pkg/pools, pkg/leak, and pkg/geocode to internal.
More remains.
