David Nadlinger cf19c9512d RELEASE_NOTES: Add entry for compiler lifetime tracking fix 
I contemplated putting this in the "Breaking changes" section,
as it might break user code that has avoided being hit by
memory corruption from the use-after free by chance (even
though it was always an accepts-illegal bug).

Robert Jördens 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.

David Nadlinger 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.

David Nadlinger 966ed5d013 master/scheduler: Fix priority/due date precedence order when waiting to prepare 
See test case – previously, the highest-priority pending run would
be used to calculate the timeout, rather than the earliest one.

This probably managed to go undetected for that long as any unrelated
changes to the pipeline (e.g. new submissions, or experiments pausing)
would also cause _get_run() to be re-evaluated.

David Nadlinger 7955b63b00 master: Always write results to HDF5 once run stage is reached 
Previously, a significant risk of losing experimental results would
be associated with long-running experiments, as any stray exceptions
while run()ing the experiment – for instance, due to infrequent
network glitches or hardware reliability issue – would cause no
HDF5 file to be written. This was especially troublesome as long
experiments would suffer from a higher probability of unanticipated
failures, while at the same time being more costly to re-take in
terms of wall-clock time.

Unanticipated uncaught exceptions like that were enough of an issue
that several Oxford codebases had come up with their own half-baked
mitigation strategies, from swallowing all exceptions in run() by
convention, to always broadcasting all results to uniquely named
datasets such that the partial results could be recovered and written
to HDF5 by manually run recovery experiments.

This commit addresses the problem at its source, changing the worker
behaviour such that an HDF5 file is always written as soon as run()
starts.

ad9910: fix asf range (#1450) 
* ad9910: fix asf range

The ASF is a 14-bit word. The highest possible value is 0x3fff, not
0x3ffe. `int(round(1.0 * 0x3fff)) == 0x3fff`.

I don't remember and understand why this was 0x3ffe since the beginning.
0x3fff was already used as a default in `set_mu()`
