The itemsize returned in a memoryview of a ctypes array is now computed from the item type, instead of dividing the total size by the length and assuming that the length is not zero.

[3.11] gh-85267: Improvements to inspect.signature __text_signature__ handling (GH-98796) (#100392)
This makes a couple related changes to inspect.signature's behaviour
when parsing a signature from `__text_signature__`.
First, `inspect.signature` is documented as only raising ValueError or
TypeError. However, in some cases, we could raise RuntimeError. This PR
changes that, thereby fixing GH-83685.
(Note that the new ValueErrors in RewriteSymbolics are caught and then
reraised with a message)
Second, `inspect.signature` could randomly drop parameters that it
didn't understand (corresponding to `return None` in the `p` function).
This is the core issue in GH-85267. I think this is very surprising
behaviour and it seems better to fail outright.
Third, adding this new failure broke a couple tests. To fix them (and to
e.g. allow `inspect.signature(select.epoll.register)` as in GH-85267), I
add constant folding of a couple binary operations to RewriteSymbolics.
(There's some discussion of making signature expression evaluation
arbitrary powerful in GH-68155. I think that's out of scope. The
additional constant folding here is pretty straightforward, useful, and
not much of a slippery slope)
Fourth, while GH-85267 is incorrect about the cause of the issue, it turns
out if you had consecutive newlines in __text_signature__, you'd get
`tokenize.TokenError`.
Finally, the `if name is invalid:` code path was dead, since
`parse_name` never returned `invalid`..

These slots are marked "should be treated as read-only" in the
table at the start of the document. That doesn't say anything about
setting them in the static struct.
`tp_bases` docs did say that it should be ``NULL`` (TIL!). If you
ignore that, seemingly nothing bad happens. However, some slots
may not be inherited, depending on which sub-slot structs are present.
(FWIW, NumPy sets tp_bases and is affected by the quirk -- though to
be fair, its DUAL_INHERIT code probably predates tp_bases docs, and
also the result happens to be benign.)
This patch makes things explicit.
It also makes the summary table legend easier to scan.
GH-87235: Make sure "python /dev/fd/9 9</path/to/script.py" works on macOS (GH-99768)
On macOS all file descriptors for a particular file in /dev/fd
share the same file offset, that is ``open("/dev/fd/9", "r")`` behaves
more like ``dup(9)`` than a regular open.
This causes problems when a user tries to run "/dev/fd/9" as a script
because zipimport changes the file offset to try to read a zipfile
directory. Therefore change zipimport to reset the file offset after
trying to read the zipfile directory.
