38c17622cc compiler: Axis-wise iteration of ndarrays
Matches NumPy. Slicing a TList reallocates, this doesn't; offsetting
couldn't be handled in the IR without introducing new semantics
(the Alloc kludge; could/should be made its own IR type).

40f59561f2 compiler: Add test for length of empty arrays [nfc]
This makes sure we are actually emitting this as an 1D array
(like NumPy does).

56010c49fb compiler/inferencer: Detect rectangular array()s
Still needs support through all the rest of the compiler, and
support for higher-dimensional arrays.

Alternatively, we could always assume ndarrays of ndarrays
are rectangular (i.e. ban array/list element types), and
detect mismatch at runtime. This might turn out to be
preferrable to be able to construct matrices from rows/columns.

`array()` is disallowed for no particularly good reason but
numpy API compatibility.

AD9910: Write correct number of bits to POW register (#1498)
* coredevice.ad9910: Add return type hints to conversion functions

* coredevice.ad9910: Make set_pow write correct number of bits
The AD9910 expects 16 bits. Thus, if writing 32 bits to the POW register, the chip would likely enter a locked-up state.

* coredevice.ad9910: Correct data alignment in write_16

Co-authored-by: Robert Jördens <rj@quartiq.de>

* coredevice.ad9910: Add function to read from 16 bit registers

ae999db8f6 compiler: Revert function call lifetime tracking fix
This reverts commits f8d1506922
and cf19c9512d.

While the commit just fixes a clear typo in the implementation,
it turns out the original algorithm isn't flexible enough to
capture functions that transitively return references to
long-lived data. For instance, while cache_get() is special-cased
in the compiler to be recognised as returning a value of Global()
lifetime, a function just forwarding to it (as seen in the
embedding tests) isn't anymore.

A separate issue is also that this makes implementing functions
that take lists and return references to global data in user code
impossible, which central parts of the Oxford codebase rely on.

Just reverting for now to unblock master; a fix is easily designed,
but needs testing.

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).

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.
