Wanda 455a7bc6c8 lib.memory: Allow setting Memory.init. 
The `init` property is already mutable, so this adds no actual new
functionality, just convenience.

Catherine 871d726ad4 build.plat: use tcl_quote instead of tcl_escape. 
The premise of `tcl_escape` is incorrect: it is not possible, by design,
to escape a single backslash inside of a Tcl {}-quoted string:

    $ tclsh
    % puts {\\}
    \\

`tcl_quote` should be used instead since it can escape arbitrary strings
(and uses the right algorithm already).

If a connect() call results in no connections being made, and it's
because there were no outputs specified at all, issue an error.

Catherine 09029cdd91 hdl._ir: remember origins of a fragment during elaboration. 
This isn't expected to result in a significant increase in memory use,
so for now it's enabled by default. Elaboration chains where it is not
desired to preserve origins can delete the `origins` attribute from
the fragment and nothing will be stored.

The interface `Fragment.origins` remains private, as is the rest of
the `Fragment` interface (including itself), but it enables certain
codebases that currently use a much more invasive technique to rely on
reading a single private field.

Amelia Cuss c40cfc9fb5 lib.enum: honor enum.nonmember. 
Use _EnumDict._member_names to determine which members to consider.
This way we don't need to redo sunder/dunder checks, and `nonmember`s
(introduced in py3.11) are correctly excluded.

This is a defacto public API, given it remains usable from py3.8
until py3.12 inclusive.  (_member_names changes from a list to a
keys-only dict for performance reasons in py3.11, but they iterate the
same.) In current Python main (i.e. what will most likely be 3.13), a
"member_names" property is added which returns those keys.
