d95e619567 compiler: Implement binary NumPy math functions (arctan2, …)
The bulk of the diff is just factoring out the implementation
for binary arithmetic implementations, to be reused for binary
function calls.

bc6fbecbda compiler, firmware: Do not expose abort() to kernels
This was only exposed for the assert implementation, and
does not exist on Zynq.

e31ee1f0b3 firmware/i2c: rewrite I2C implementation
* Never drive SDL or SDA high. They are specified to be open
  collector/drain and pulled up by resistive pullups. Driving
  high fails miserably in a multi-master topology (e.g. with
  a USB I2C interface). It would only ever be implemented to
  speed up the bus actively but that's tricky and completely
  unnecessary here.
* Make the handover states between the I2C protocol phases (start, stop,
  restart, write, read) well defined. Add comments stressing those
  pre/postconditions.
* Add checks for SDA arbitration failures and stuck SCL.
* Remove wrong, misleading or redundant comments.

3f0cf6e683 runtime: Stop kernel CPU before restarting comms CPU on panic
Before, the system would enter a boot loop when a panic occurred
while the kernel CPU was active (and panic_reset == 1), as
kernel::start() for the startup kernel would panic.

* The value varies greatly whether netboot is enabled or not.
* There is no simple solution to detect has_ethmac in the linker script and set the value accordingly.
* The space check is an imperfect solution that will be superseded by stack pointer limits.
* Left commented out so we can re-enable it manually during development if stack corruption is suspected.

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.

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.
