Catherine 6965abeefa abc, abc9_exe: fix build on WASI (and others with `const* stdout`). 
C does not guarantee that stdout/stderr can be reassigned.
Most platforms do make them assignable, however musl and WASI that
is based on musl do not. WASI does not have `dup2()`; instead it has
its own non-portable version of it that can only assign to previously
allocated fds.

Update the stream redirection code so that it does the right thing
on WASI and other platforms.

Catherine 411b6e98cd abc, abc9_exe: respect `-q` when built with linked ABC. 
This is mostly important for YoWASP builds, since those do not have
a way to build with external ABC (I prototyped it but for some reason
ABC always segfaults when built as an independent Wasm binary...)

Martin Povišer 72a4022a10 ast/simplify: Retire 'at_zero' flag 
Now that all the callsites pass in 'false' for the flag (or propagate
the flag on recursion), we can retire it.

Martin Povišer 4fceeb3b32 ast/simplify: Use clone_at_zero() for "at_zero" evaluations 
The correct way of using the 'at_zero' regime of simplify is to perform
the simplification on a cloned AST subtree, otherwise the "at_zero"
evaluation seeps into the main tree.

Move the effect of the 'at_zero' flag to the cloning itself, so that
the simplify flag can be retired. We assume we can rely on id2ast in
the new clone method.

Martin Povišer 77d4b5230e ast: Move to a new helper method to print input errors 
It's a repeating pattern to print an error message tied to an AST
node. Start using an 'input_error' helper for that. Among other
things this is beneficial in shortening the print lines, which tend
to be long.

Martin Povišer f0ae046c5a opt_share: Fix input confusion with ANDNOT, ORNOT gates 
Distinguish between the A, B input ports of `$_ANDNOT_`, `$_ORNOT_`
gates when considering those for sharing. Unlike the input ports of the
other supported single-bit gates, those are not interchangeable.

Fixes #3848.

Charlotte 3f29bdbbc5 smt2: py3.12+: avoid SyntaxWarning. 
Python 3.12 emits a SyntaxWarning when encountering invalid escape
sequences.  They still parse as expected.  Marking these raw produces
the same result without the warnings.

proc_prune: avoid using invalidated iterator

Charlotte 63e4114233 proc_prune: avoid using invalidated iterator 
An `std::vector<T>::reverse_iterator` stores the
`std::vector<T>::iterator` which points to the (forwards-ordered)
*following* item.  Thus while `vec.rbegin()` dereferences to the final
item of `vec`, the iterator it wraps (`vec.rbegin().base()`) is equal to
`vec.end()`.

In the remove case here, we advance `it` (backwards), erasing the item
we just advanced past by grabbing its (pre-increment) base
forward-iterator and subtracting 1.

The iterator maths here is obviously all OK, but the forward-iterator
that `it` wraps post-increment actually points to the item we just
removed.  That iterator was invalidated by the `erase()` call.

That this works anyway is (AFAICT) some combination of luck and/or
promises that aren't part of the C++ spec, but MSVC's debug iterator
support picks this up.

`erase()` returns the new iterator that follows the item just erased,
which happens to be the exact one we want our reverse-iterator to wrap
for the next loop; we get a fresh iterator to the same base, now without
the preceding item.
