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.

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.

sayma: use GTP_CLK1 to clock DRTIO satellite transceiver
...
This is required to get constant skew between the DRTIO transceiver clock
(which then generates the RTIO clock) and the siphaser reference clock.
Both the Si5324 and the RTM clock tree have non-deterministic in-to-out skew
at 150MHz due to dividers.

sayma: put RTM clock tree into the siphaser loop
...
* Fixes one bug where siphaser was one Si5324 output and the rest of the
system was clocked by the other. With the Si5324 settings we have, skew
between the outputs is not controlled.
* Puts the coaxial cable between AMC and RTM into the siphaser loop.

* Break the HMC830 init into separate functions for general purpose (but, integer-N) init, setting dividers and checking lock
* Use 1.6mA ICP (which the loop filter was optimized for)
* Go through the data sheet carefully and set all registers to the correct value (e.g. ensure that all settings are correctly optimized for integer-N usage)
* Change divider values (now using 100MHz PFD, which should give lower noise in theory)
