whitequark 0edae64afb firmware: fix TOCTTOU race in sync/async RPC code. 
Before this commit, the main loop in session code was laid like:

  1. process_kern_queued_rpc
  2. process_host_message
  3. process_kern_message

If a host message (such as an RPC reply) caused the kernel to exit,
then any async RPCs would not complete, since RunFinished immediately
shuts down the kernel.

Fix this by reordering 1 and 2.

David Nadlinger b482f5feae firmware: Use larger ARP cache 
This works around a problematic interaction between ARP cache
expiry in smoltcp (with its 3 seconds timeout before a discovery
request is sent) and our TCP keepalive settings, where the timeout
is reached before the keepalive had a chance to be sent.

GitHub: Closes #1150.
