I had intended for this to be a small change.
I was going to just add context.Context to the BlobReceiver interface,
but then I saw blob.Fetcher could also use one, so I decided to do two
in one CL.
And then it got a bit infectious and ended up touching everything.
I ended up doing SubFetch in the process by necessity.
At a certain point I finally started using context.TODO() in a few
spots, but not too many. But removing context.TODO() will come in the
future. There are more blob storage interfaces lacking context, too,
like RemoveBlobs.
Updates #733

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.
