LISTSERV 16.5 - XROOTD-DEV Archives

this PR converts all use of distutils to either use existing CPython libraries or
use setuptool's versions of them, as advocated by the PyPA.

The XRootD docs are not clear on how to run the test suite(or at least don't make it easy to find at all), so while I'd really appreciate it if someone could tell me how to do that at there doesn't seem to be any CI hooked up on GitHub here's an example Dockerfile that demonstrates on my fork that things still build fine
