[3.13] gh-139283: correctly handle size limit in cursor.fetchmany() (GH-139296) (#139444)
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.

Within libexpat, a parser created via `XML_ExternalEntityParserCreate`
is relying on its parent parser throughout its entire lifetime.
Prior to this fix, is was possible for the parent parser to be
garbage-collected too early.

work).

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.

gh-118981: multiprocessing.popen_spawn_posix, fix potential hang (gh-118982)

fix potential hang.

It can happen that the child crashes right in the beginning for whatever reason. In this case, the parent will hang when writing into the pipe, because the child fd is not closed yet.

The normal pattern is to close the child fds right after the child proc is forked/executed/spawned, so when the child dies, then also the pipes will be closed, and there will be no hang (the parent gets SIGPIPE instead).
