Robert Jördens 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)

for #1143

David Nadlinger 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).

David Nadlinger 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.

David Nadlinger 11e8c9d5f7 coredevice: Add Core.wait_until_mu()

 2018-11-03 20:33:19 +08:00
David Nadlinger 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.

David Nadlinger 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).
