long lived uplinks could just hold on to connections forever
if their client to the storagenode or satellite isn't closed.
this will prevent that from happening on the client. more
changes will be necessary to add appropriate prevention on
the servers.

drpc will call Close on any transport we pass to it, but some
transports (like tls.Conn) will attempt to notify the remote
side of things. we don't want to do that, so pass a new
interface that just closes the underlying socket.

keep a pool of connections open when dialing for drpc. this
makes it so that long lived clients (like lib/uplink's Project)
don't continue to use a bad connection forever. it also allows
for concurrent rpcs.

we spawned a goroutine to wait on the context's done
channel sending the error afterward, but we forgot
to ensure the context was eventually done, so the
goroutine would be leaked until then.
instead, we can just do a select on two channels to
get the error rather than spawn a goroutine which
makes it impossible to leak a goroutine.

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.
