d6fcc0529f coredevice: Imperative mood in docstrings [nfc]
This follows Python conventions (PEP257) and unifies the style with
other comments.

cbdef0225c ttl: Add target RTIO time argument to timestamp/count functions
Software-based tracking of timestamps is problematic (e.g. when
using DMA, see GitHub #1113).

17a5fb2dce ttl: Remove error-prone sync() calls
These methods are problematic, as with DMA in the picture, the
timestamp member variables did not necessarily reflect the last
submitted event timestamp (see GitHub #1113).

sync() is only very rarely used in typical experimental code, so
the methods are removed without a transition period.
Core.wait_until() can be used to busy-wait for a specified RTIO
timestamp value on the core device CPU instead.

11e8c9d5f7 coredevice: Add Core.wait_until_mu()

cbfbe24d7a ttl: Remove broken TTLClockGen.sync
The code currently doesn't compile because of a typo in the timestamp
field name. However, tracking event timestamps in software is
problematic anyway (e.g. with DMA, see GitHub #1113), so just remove
`sync()` altogether.

64b9a377da master: Factor RIDCounter out into own module, explain worker_db module [nfc]
The docstrings are quite minimal still, but should already
help with navigating the different layers when getting
accustomed with the code base.

RIDCounter was moved to its own module, as it isn't really
related to the other classes (used from master only).

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.

38d60100ff firmware: optimize dma_record_output.

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.

The HMC7043 outputs poorly controlled signals when adjusting

and only triggers synchronizations when SYSREF is stable.
