s_client accepts host/port as positional argument.

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.

Fix memory leaks in CTLOG_new_from_base64

Move the call to ct_base64_decode(), which allocates, until after
the check for NULL output parameter.

Also place a cap on the number of padding characters used to decrement
the output length -- any more than two '='s is not permitted in a
well-formed base64 text.  Prior to this change, ct_base64_decode() would
return a length of -1 along with allocated storage for an input of
"====".
