(unnamed) (text/plain)

In an attempt to slice off as much non-NSS specific changes as possible from
the larger libnss patch proposed in [0], the attached patch contains the ssl
test harness refactoring to support multiple TLS libraries.

The changes are mostly a refactoring to hide library specific setup in their
own modules, but also extend set_server_cert() to support password command
which cleans up the TAP tests from hands-on setup and teardown.
