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.

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.

2648b1b7a1 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.

Previously if one dashboard overrode a channel this was not visible on
any other dashboard - the channel appeared to operate normally.

e4d48a78eb drtio: wait for remote to ack TSC synchronization
Sayma takes a long time after TSC sync to align SYSREF, and this caused two issues:
1. Aux packets getting lost and causing error reports
2. DRTIO links reported up and kernels proceeding despite the DACs not being properly synced.
