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.

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 .

firmware: migrate to Rust 1.28.0.
...
This also updates / is a prerequisite for updating smoltcp.
Rationale for changes made:
* compiler_builtins is now shipped in the rust prefix.
* rustc's libpanic_unwind no longer works for us because it
has a hard dependency on Box (and it's a horrible hack);
fortunately, we only ever needed a personality function
from it.
* panic and oom handlers are now set in a completely different
way.
* allocators are quite different (and finally stable).
* NLL caused internal compiler errors in runtime, so code using
NLL was rewritten to not rely on it and it was turned off.
