smtp: set auth correctly

Regression since 7.69.0 and 68fb25fa3fcff.

The code wrongly assigned 'from' instead of 'auth' which probably was a
copy and paste mistake from other code, leading to that auth could
remain NULL and later cause an error to be returned.

libssh: avoid options override by configuration files

libssh: avoid options override by configuration files

Previously, options set explicitly through command line options could be
overridden by the configuration files parsed automatically when
ssh_connect() was called.

By calling ssh_options_parse_config() explicitly, the configuration
files are parsed before setting the options, avoiding the options
override. Once the configuration files are parsed, the automatic
configuration parsing is not executed.

runtests: when <killserver> mentions http, kill http/2 too

Since the http2 test server is a mere proxy that needs to know about the
dynamic port the HTTP server is using, it too needs to get restarted
when the http server is killed.

transfer: Switch PUT to GET/HEAD on 303 redirect

Prior to this change if there was a 303 reply to a PUT request then
the subsequent request to respond to that redirect would also be a PUT.
It was determined that was most likely incorrect based on the language
of the RFCs. Basically 303 means "see other" resource, which implies it
is most likely not the same resource, therefore we should not try to PUT
to that different resource.

Refer to the discussions in #5237 and #5248 for more information.
