This allows the user to provide the target host and optional port to
openssl s_client as an optional positional argument, rather than as the
argument to the -connect flag. This rationalises the user experience of
s_client: given that the only logical purpose of s_client is to connect
to a host, it is difficult to understand why there is an (effectively
mandatory) command option to pass to make that happen.

This patch forbids providing *both* -connect and the positional
argument, because it would likely be too difficult to reconcile.
Otherwise, using the positional argument behaves exactly the same as
using -connect does.

and bignums.  These have been refactored into their own file, along with
their error displays.  The formatting follows the output format used
on error, except that bignums of sixty four bits or less are displayed
in a more compact one line form.

Added a TEST_note function for producing output without file and line
information.

Update the three tests that call BN_print so they use the new test
infrastructure instead.

This does things as per the recommendation in the TLSv1.3 spec. It also
means that the server will always choose its preferred ciphersuite.
Previously the server would only select ciphersuites compatible with the
session.
