libuplink was incorrectly setting timeouts to 10 seconds still, but
should have been at least 10 minutes. the order sender was setting them
to 1 hour. we don't want timeouts in uplink-side logic as it establishes
a minimum rate on tcp streams.
instead of all of this, just use tcp keep alive. tcp keep alive packets are
sent every 15 seconds and if the peer stops responding the connection
dies. this is enabled by default with go. this will kill tcp connections
when they stop working.

It provides an abstraction around the rpc details so that one
can use dprc or gprc with the same code. It subsumes using the
protobuf package directly for client interfaces as well as
the pkg/transport package to perform dials.
