*gh-112532: Isolate abandoned segments by interpreterMimalloc segments are data structures that contain memory allocations alongwith metadata. Each segment is "owned" by a thread. When a thread exits,it abandons its segments to a global pool to be later reclaimed by otherthreads. This changes the pool to be per-interpreter instead of process-wide.This will be important for when we use mimalloc to find GC objects in the`--disable-gil` builds. We want heaps to only store Python objects from asingle interpreter. Absent this change, the abandoning and reclaiming processcould break this isolation.* Add missing '&_mi_abandoned_default' to 'tld_empty'

…tructing protocol classes (#113401)- Only attempt to figure out whether protocol members are "method members" or not if the class is marked as a runtime protocol. This information is irrelevant for non-runtime protocols; we can safely skip the risky introspection for them.- Only do the risky getattr() calls in one place (the runtime_checkable class decorator), rather than in three places (_ProtocolMeta.__init__, _ProtocolMeta.__instancecheck__ and _ProtocolMeta.__subclasscheck__). This reduces the number of locations in typing.py where the risky introspection could go wrong.- For runtime protocols, if determining whether a protocol member is callable or not fails, give a better error message. I think it's reasonable for us to reject runtime protocols that have members which raise strange exceptions when you try to access them.PEP-544 clearly states that all protocol member must be callable for issubclass() calls against the protocol to be valid -- and if a member raises when we try to access it, there's no way for us to figure out whether it's a callable member or not!

*gh-112532: Tag mimalloc heaps and pagesMimalloc pages are data structures that contain contiguous allocationsof the same block size. Note that they are distinct from operatingsystem pages. Mimalloc pages are contained in segments.When a thread exits, it abandons any segments and contained pages thathave live allocations. These segments and pages may be later reclaimedby another thread. To support GC and certain thread-safety guarantees infree-threaded builds, we want pages to only be reclaimed by thecorresponding heap in the claimant thread. For example, we want pagescontaining GC objects to only be claimed by GC heaps.This allows heaps and pages to be tagged with an integer tag that isused to ensure that abandoned pages are only claimed by heaps with thesame tag. Heaps can be initialized with a tag (0-15); any page allocatedby that heap copies the corresponding tag.* Fix conversion warning

Disable toc_object_entries, new in Sphinx 5.2.3

Allow `os.PathLike` objects to be passed as patterns to `pathlib.Path.glob()` and `rglob()`. (It's already possible to use them in `PurePath.match()`)While we're in the area:- Allow empty glob patterns in `PathBase` (but not `Path`)- Speed up globbing in `PathBase` by generating paths with trailing slashes only as a final step, rather than for every intermediate directory.- Simplify and speed up handling of rare patterns involving both `**` and `..` segments.

Use `_make_child_entry()` rather than `_make_child_relpath()` to retrievepath objects for directories to visit. This saves the allocation of onepath object per directory in user subclasses of `PathBase`, and avoids asecond loop.This trick does not apply when walking top-down, because users can affectthe walk by modifying *dirnames* in-place.A side effect of this change is that, in bottom-up mode, subdirectories ofeach directory are visited in reverse order, and that this order doesn'tmatch that of the names in *dirnames*. I suspect this is fine as theorder is arbitrary anyway.
