lots of stuff here.
introduces a streaming framework for the RPC system with flow control.
new authentication primitives for the RPC system. this is used to create
a persistent "job manager" process (via wsh) that can survive
disconnects. and then a jobcontroller in the main server that can
create, reconnect, and manage these new persistent jobs.
code is currently not actively hooked up to anything minus some new
debugging wsh commands, and a switch in the term block that lets me test
viewing the output.
after PRing this change the next steps are more testing and then
integrating this functionality into the product.
This makes it possible to send wsh commands from wsh on a remote session
to wavesrv running locally. The exact behavior of running those commands
isn't implemented, but the underlying interface is added here.
lots of changes. new wshrpc implementation. unify websocket, web,
blockcontroller, domain sockets, and terminal inputs to all use the new
rpc system.
lots of moving files around to deal with circular dependencies
use new wshrpc as a client in wsh cmd
