[issue21040] socketserver: use selectors module

[Charles-François Natali]

New submission from Charles-François Natali:

This patch updates the socketserver module to use selectors.
It's simpler, will use poll() when available, and also fixes a bug where the timeout would not be recomputed upon EINTR.

Note that I removed an EINTR-handling test from test_socketserver because test_selectors already covers this in a more clean and robust way.
