Now that the peer element is validated we must send valid point data.
This should have been done in the beginning anyways, but since the
point data was not previously validated this test still passed.
Since this particular unit test is really testing timeouts we can just
use the commit buffer for other tests since it contains a valid scalar
and point.
The return from l_ecc_point_from_data was not being checked for NULL,
which would cause a segfault if the peer sent an invalid point.
This adds a check and fails the protocol if p_element is NULL, as the
spec defines.

Stop using l_pem_load_certificate which has been removed from ell, use
the same functions to load certificate files to validate them as those
used by the TLS implementation itself.
This is a helper/shortcut to get_ordered_networks (plural). In nearly
all the autotests we had (roughly) the same block of code:
ordered_network = get_ordered_networks()[0]
self.assertNotEqual(ordered_network, None)
self.assertEqual(ordered_network.name, "someSsid")
Rather than having to do this, we can simplify and just have a single
call to get_ordered_network, which takes the SSID. If the SSID is not
found, we raise an exception. This avoids needing both asserts since
we are guarenteed that the return is valid and the SSID matches.
This also avoids possible issues with multiple networks showing up in
the GetOrderedNetworks call. Eventually test-runner will support running
tests on real wireless hardware, so its possible we could pick up
unexpected networks in the scan.
At some point a stray ';' got added into an autotest in a section
of code that is heavily copy pasted. So in turn nearly all the autotests
have this stray ';' after list_devices (and a few in other places).
Check that the TLS logic has verified the server is trusted by the CA if
one was configured. This is more of an assert as ell intentionally only
allows empty certificate chains from the peer in server mode (if a CA
certficate is set) although this could be made configurable.
