[3.13] gh-82951: Fix serializing by name in pickle protocols < 4 (GH-122149) (GH-122264)
Serializing objects with complex __qualname__ (such as unbound methods and
nested classes) by name no longer involves serializing parent objects by value
in pickle protocols < 4.

TSan doesn't fully recognize the synchronization via I/O, so ensure that
socket name is retrieved earlier and use a different socket for sending
the "STOP" message.

[3.13] gh-117482: Simplify the Fix For Builtin Types Slot Wrappers (gh-121932)
In gh-121602, I applied a fix to a builtin types initialization bug.
That fix made sense in the context of some broader future changes,
but introduced a little bit of extra complexity. For earlier versions
those future changes are not relevant; we can avoid the extra complexity.
Thus we can revert that earlier change and replace it with this one,
which is more focused and conceptually simpler. This is essentially
the implementation of an idea that @markshannon pointed out to me.
Note that this change would be much smaller if we didn't have to deal
with repr compatibility for builtin types that explicitly inherit tp slots
(see expect_manually_inherited()). The alternative is to stop
*explicitly* inheriting tp slots in static PyTypeObject values,
which is churn that we can do separately.

GH-120754: Add more tests around seek + readall (GH-122103)
In the process of speeding up readall, A number of related tests
(ex. large file tests in test_zipfile) found problems with the
change I was making. This adds I/O tests to specifically test these
cases to help ensure they don't regress and hopefully make debugging
easier.
This fixes the flakiness in:
* test_inspect_keeps_globals_from_inspected_file
* test_inspect_keeps_globals_from_inspected_module
The output already includes newlines. Adding newlines for every entry in
the output list introduces non-determinism because it added '\n' in
places where stdout is flushed or some buffer becomes full.
The regex also needed to be updated because pyrepl includes control
characters -- the visible output on each line doesn't immediately follow
a newline character.
