Catherine c649045f35 lib.data: add a diagnostic for slicing data.View. 
This is meaningless for a view but meaningful for the underlying value.

Fixes #1375.

Catherine 0140fe27e2 hdl._dsl: forbid empty string as submodule name. 
This is semantically ambiguous and breaks the RTLIL emitter.

Fixes #1209.

Catherine 7870eb344b sim: document. 
This commit includes additional non-documentation changes, related to
issues found while documenting it:
- `Simulator.run_until()` no longer accepts a `run_passive=` argument.
  Passive no longer exist and in any case defaulting to `False` does not
  make a lot of sense from an API perspective.
- `add_clock()`'s `phase=` argument, when specified, no longer has
  `period/2` added to it. This wasn't the documented behavior in first
  place and it makes no sense to do that.
- `add_clock()` raises a `NameError` if a clock domain does not exist,
  instead of `ValueError`.
- `add_clock()` raises a `DriverConflict` if a clock domain is already
  being driven by a clock, instead of `ValueError`.
- GTKWave is no longer a part of the installation instructions, and both
  Surfer and GTKWave are recommended (in this order).

Wanda 77dab7884c hdl._dsl: raise an error when modifying an already-elaborated Module. 
This renames the `FrozenMemory` exception to `AlreadyElaborated`
and reuses it for modules.

Fixes #1350.

Wanda 1d2b9c309e back.rtlil: set read port init to all-x. 
This is an unfortunate necessity needed to fix memory inference regressions
introduced when we switched to using v2 cells. A better approach, compatible
with RFC 54, will need to be figured out for Amaranth 0.6.

Fixes #1011.

Catherine 994fa81599 Implement RFC 36. 
This feature does not exactly follow the RFC because the RFC as written
is not implementable; the treatment of async resets in `tick()` triggers
had to be changed. In addition, iterating a trigger was made to watch
for missed events, in case the body of the `async for` awaited for too
long.

Catherine f637530093 sim: move Command from core to _pycoro. 
Simulator commands are deprecated and will be removed once RFC 36 is
implemented and released. They are an artifact of the old API.

Catherine eef248a080 pyproject: write XML coverage after running the testsuite. 
This is particularly useful with IDEs that can display coverage in
the editor, e.g. VS Code with the "Coverage Gutters" extension.

Wanda 25c3531e93 vendor.*: fix [io]_domain propagation when creating buffers. 
Closes #1347.

Wanda 9e82d54302 lib.io: make [io]_domain attributes always present. 
Having conditionally-present attributes causes more problems than it's
worth (see #1347). Just make them contain `None` when irrelevant.
