1fe7bd010f hdl: remove subclassing of AnyValue and Property. 
This subclassing is unnecessary and makes downstream code more complex.
In the new IR, they are unified into cells with the same name anyway.
Even before that, this change simplifies things.

115954b4d9 lib.fifo: add Memory as submodules instead of its ports. [NFC] 
This makes the generated netlist very slightly nicer.

4da8adf7ba back.rtlil: remove _SyncBuilder. NFC 
Amaranth doesn't emit sync rules for a while since these are private
for the Yosys Verilog frontend.

but were lost during rebasing.

ea3d6c9557 docs/reference: document compat guarantee, importing, shapes. 
This commit also contains a related semantic change: it adds `Shape`
and `ShapeCastable` to the `__all__` list in `amaranth.hdl`. This is
consistent with the policy that is laid out in the new documentation,
which permits such additions without notice.

5dd1223cf8 amaranth.hdl: start all private names with an underscore. 
This change completes commit 9dc0617e and makes all the tests pass.
It corresponds with the ongoing langauge reference documentation effort.

Fixes #781.

cf83193bf9 amaranth.hdl: rename internal modules to begin with an underscore. 
This change completely breaks the library. It is done separately just
to make sure git tracks renames as such.

7f76914b74 Implement RFC 17: Remove log2_int. 
Reexports of `amaranth.utils` functions are removed from
`amaranth._utils` to avoid a circular import issue (for `deprecated`).
Since this is a private module, this should not be a problem.

7e18786c97 hdl.ast: use operator.index instead of int. 
This ensures things like `Const(1.5)` raise an error.

`int(operator.index())` is used since `operator.index(True)` on Python
3.9 and earlier returns `True` instead of `1`.

5d9ad62f36 build.plat,vendor: start build.sh with #!/bin/sh. 
The build scripts generated by Amaranth are designed to be invoked by
directly running them with any shell (some of them will re-invoke
themselves with `bash` specifically, when it's a toolchain requirement),
and they're not currently marked executable, so there's no shebang.

Add a shebang line to improve compatibility with cases where they are
treated as executables in their own right.

b9c2404f22 lib.wiring: make values of In and Out be strings "In" and "Out". 
Their `str()` and `repr()` values are already that; and the 0 and 1
don't make sense. The RFC leaves it unspecified.
