gh-126631: gh-137996: fix pre-loading of `__main__`
The `main_path` parameter was renamed `init_main_from_name`, update the
forkserver code accordingly. This was leading to slower startup times when people
were trying to preload the main module.

Without the ability to set required capabilities, the REPL cannot
function properly (syntax highlighting and multiline editing can't
work).
We refuse to work in this degraded state.

Passing a negative or zero size to `cursor.fetchmany()` made it fetch all rows
instead of none.
While this could be considered a security vulnerability, it was decided to treat
this issue as a regular bug as passing a non-sanitized *size* value in the first
place is not recommended.

* Only lock the SSL context, not the SSL socket.
This solves a deadlock when a socket is blocked while waiting on data,
which ended up causing a major regression in 3.13.6 (see gh-137583).

gh-136914: Fix support of cached functions and properties in DocTest's lineno computation (GH-136930)
Previously, DocTest's lineno of functions and methods decorated with
functools.cache(), functools.lru_cache() and functools.cached_property()
was not properly returned (None was returned) because the
computation relied on inspect.isfunction() which does not consider the
decorated result as a function.
We now use the more generic inspect.isroutine(), as elsewhere
in doctest's logic.
Also, added a special case for functools.cached_property().

There was a deadlock originally seen by Memray when a daemon thread
enabled or disabled profiling while the interpreter was shutting down.
I think this could also happen with garbage collection, but I haven't
seen that in practice.
The daemon thread could be hung while trying acquire the global rwmutex
that prevents overlapping global and per-interpreter stop-the-world events.
Since it already held the main interpreter's stop-the-world lock, it
also deadlocked the main thread, which is trying to perform interpreter
finalization.
Swap the order of lock acquisition to prevent this deadlock.
Additionally, refactor `_PyParkingLot_Park` so that the global buckets
hashtable is left in a clean state if the thread is hung in
`PyEval_AcquireThread`.

There were a few thread-safety issues when profiling or tracing all
threads via PyEval_SetProfileAllThreads or PyEval_SetTraceAllThreads:
* The loop over thread states could crash if a thread exits concurrently
(in both the free threading and default build)
* The modification of `c_profilefunc` and `c_tracefunc` wasn't
thread-safe on the free threading build.
