sslutil: move sslkwargs logic into internal function (API)
As the previous commit documented, sslkwargs() doesn't add any
value since its return is treated as a black box and proxied
to wrapsocket().
We formalize its uselessness by moving its logic into a
new, internal function and make sslkwargs() return an empty
dict.
The certificate arguments that sslkwargs specified have been
removed from wrapsocket() because they should no longer be
set.
# Dummy extension that adds a delay after acquiring a lock.
#
# This extension can be used to test race conditions between lock acquisition.
