Use alpmlist_to_pylist2 to pass NULL to the package function to prevent
arbitrary memory to be passed to Py_INCREF.

Closes: FS#71261

Architectures are now a list and pyalpm's pycman was not able to handle
this. For backwards compatibility convert a string to a list.

As syncdb's are not signed in Arch Linux providing SIG_DATABASE returns
no search results.

Fixes: FS#71146

In 67596333 we removed the total download callback as it no
longer exists in pacman but forgot to clean up enum for it leading to
the a segfault and callbacks being wrong.

Minor update to resolve compatibility with libalpm callback api.

For frontends to manage their callback state libalpm added a void
*context argument as this is ABI breakage.

This release adds compatibility with libalpm v13 and is not backwards
compatible.

Pacman now supports multiple 'Architecture' values and change the
setter/getter library functions which now accepts a list of
architectures.

The "total download" callback has been removed from libalpm in
1e60a5f00674a9a9b0

alpm_db_update now supports updating multiple databases at once the so
called parallel download feature. This requires an adjustment of the
alpm_db_update function call.

alpm_db_search now returns an int and set's pm_errno when the result is
-1 add a todo as this needs to be handled later

Allows us to test our next branch periodically with a Gitlab CI weekly
schedule.

It is easier to read if you don't need to try to figure out the flow of
a list of strings, and the non-issueful setuptools.Extension()
invocation, as they relate to __main__.

It's declarative and easier to read, and comes with convenient helper
functions for reading files.

The source code headers all state "or later", though some specify 2+ and
some specify 3+.

The code in find_file never matched the files itself but a tuple of
file, 0, 0).

Fixes: FS#69414

This function can't be tested and it would be testing CPython.
