3e84ec2bf1 coredevice.ad9910: Fix phase tracking ref_time passing
This is difficult to test without hardware mocks or some
form of phase readback, but the symptom was that e.g.
`self.dds.set(…, ref_time=now_mu() - 1)` would fail
periodically, that is, whenever bit 32 of the timestamp
would be set (which would be turned into the sign bit).

This is a fairly sinister issue, and is probably a compiler
bug of some sort (either accepts-invalid or wrong type inference).

19748fe495 ad9910: fix RTIO fine timestamp nudging
Previously the TSC was truncated to an even coarse RTIO periods before doing
the setting SPI xfer. Afterwards the the IO update pulse would introduce
at least one but less than two RTIO cycles. Ultimately the RTIO TSC was
truncated again to even. If the SPI xfer takes an odd number of RTIO
periods, then a subsequent xfer would collide.

68aad3e482 firmware: fix TOCTTOU race in sync/async RPC code.
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.

This now reliably locates the SYNC_CLK-IO_UPDATE edge by doing two

It also works well when one delay is very close to the edge.
And it correctly identifies which (start or stop) pulse hit or crossed
the SYNC_CLK edge.

ba4bf6e59b kasli: don't pass rtio pll feedback through bufg
UG472: "The MMCM performance increases because the
feedback clock is not subjected to noise on the core supply since it
never passes through a block powered by this supply."

2f6d3f79ff ad9910: add phase modes
* simplified and cross-referenced the explanation of the different
  phase modes.
* semantically and functionally merged absolute and tracking/coherent
  phase modes.
* simplified numerics to calculate phase correction
* added warning about possible inconsistency with DMA and default
  phase mode
* restricted __all__ imports
* moved continuous/relative phase offset tracking from an instance
  variable to a "handle" returned by set()/set_mu() in order to avoid
  state inconsistency with DMA (#1113 #1115)
