ssl: prompt passphrase of client key file via ui.getpass() (issue4648)

This is necessary to communicate with third-party tools through command-server
channel. This requires SSLContext backported to Python 2.7.9+.

It doesn't look nice to pass ui by sslkwargs, but I think it is the only way
to do without touching various client codes including httpclient (aka http2).
ui is mandatory if certfile is specified, so it has no default value.

BTW, test-check-commit-hg.t complains that ssl_wrap_socket() has foo_bar
naming. Should I bulk-replace it to sslwrapsocket() ?
