38d60100ff firmware: optimize dma_record_output. 
This removes a number of bounds checks and adds a fast path for
outputting exactly one word to DMA, which is the most common
operation.

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.

a44f8282dc test_performance: relax network speed to 2 MB/s 
At QUARTIQ I am getting 2.4/2.3 MB/s and with single switch at M-Labs we
apparently regularly met 2.2/2.2 MB/s. But with the current multiple
switches and one of them being a problematic switch that triggered #837
it looks like it is a tad slower.

9bf189ca10 test: relax timing requirements when not using DMA handle 
core_dma.playback() without handle incurs a round-trip with the comms
