The update command implementation runs over files that are independent
from each other. As such, the overall update operation can be trivially
parallelised to speed things up.

This change introduces  The list of files that need to be
compared/updated is collected in a first past. This list is then given
to a multiprocessing pool to farm out the actual update of each
individual file. The amount of parallelism is controlled through a new
"jobs" parameter, command line option and environment variable. If no
value is given for this option, all CPUs are used.

I noticed this chance for improvement when doing a test run of the
update of .po files for the Spanish translation of the CPython
documentation. Local numbers in my 8-core, hyper-threaded AMD Ryzen 7
