[sbws/m12] chg: scanner: Move to concurrent.futures

commit e11faefd010ca0447f10d79ca9da1ef71f37a1d9 Author: juga0 <juga(a)riseup.net> Date: Sat Jun 19 16:07:20 2021 +0000 chg: scanner: Move to concurrent.futures away from multiprocessing, because it looks like we hit python bug 22393, in which the pool hangs forever when a worker process dies. We don't know the reason why a worker process might due, maybe oom. See https://stackoverflow.com/questions/65115092/occasional-deadlock-in-multipr…, We also run into several other issues in the past with multiprocessing. Concurrent.futures has a simpler API and is more modern.

commit fce99957e238706912a6e940c878648b6ebd8f2b Author: Nick Mathewson <nickm(a)torproject.org> Date: Mon Jun 28 09:08:31 2021 -0400 Suppress strict-prototypes warning on NSS pk11pub.h header We already did this in a couple of places, but there are more that we didn't get. This is necessary for systems with versions of NSS that don't do their prototypes properly.
