Anders Kaseorg b6736eb0a5 Use protobuf’s Gzip{Input,Output}Stream wrapper around zlib 
This removes our direct zlib dependency (although of course protobuf
still uses it internally), removes a fixed 4 MiB buffer and its
corresponding limit on the terminal size, reduces some string copying,
and deletes some code.
