daemon: Buffer data sent to clients by the 'export-path' RPC.
Before that we'd have STDERR_WRITE round trips for very small amounts of
data, ranging from a few bytes for the metadata of nars to the size of
one file being exported.
With this change, something like:
guix archive --export /gnu/store/5rrsbaghh5ix1vjcicsl60gsxilhjnf2-coreutils-8.25 | dd of=/dev/null
reports a throughput of 35 MB/s instead of 25 MB/s before.
* nix/nix-daemon/nix-daemon.cc (TunnelSink): Inherit from 'BufferedSink'
rather than 'Sink'. Rename 'operator ()' to 'write'.
(performOp) <wopExportPath>: Add 'sink.flush' call.
