Fix error in BIO_get_ktls_send() and BIO_get_ktls_recv()

If we were using a different type of BIO than a socket BIO then
BIO_get_ktls_send() and BIO_get_ktls_recv() could return the wrong
result.

The above occurred even if KTLS was disabled at compile time - so we should
additionally ensure that those macros do nothing if KTLS is disabled.

Finally we make the logic in ssl3_get_record() a little more robust when
KTLS has been disabled.

Add a way for the application to get OpenSSL configuration data

asn1parse: avoid double free

|str| was used for multiple conflicting purposes.  When using
'-strictpem', it's used to uniquely hold a reference to the loaded
payload.  However, when using '-strparse', |str| was re-used to hold
the position from where to start parsing.

So when '-strparse' and '-strictpem' are were together, |str| ended up
pointing into data pointed at by |at|, and was yet being freed, with
the result that the payload it held a reference to became a memory
leak, and there was a double free conflict when both |str| and |at|
were being freed.

The situation is resolved by always having |buf| hold the pointer to
the file data, and always and only use |str| to hold the position to
start parsing from.  Now, we only need to free |buf| properly and not
|str|.

Separate the lookup test

This fixes the "verifying the alias" case.
Actually, while working on it, I realized that conceptually we were
testing the 2 different behaviours of `EC_GROUP_check_named_curve()` at
the same time, and actually not in the proper way.

I think it's fair to assume that overwriting the curve name for an
existing group with `NID_undef` could lead to the unexpected behaviour
we were observing and working around.
Thus I decided to separate the lookup test in a dedicated simpler test
that does what the documentation of `EC_GROUP_check_named_curve()`
suggests: the lookup functionality is meant to find a name for a group
generated with explicit parameters.

In case an alternative alias is returned by the lookup instead of the
expected nid, to avoid doing comparisons between `EC_GROUP`s with
different `EC_METHOD`s, the workaround is to retrieve the `ECPARAMETERS`
of the "alias group" and create a new explicit parameters group to use
in `EC_GROUP_cmp()`.

EVP_*Update: ensure that input NULL with length 0 isn't passed

Even with custome ciphers, the combination in == NULL && inl == 0
should not be passed down to the backend cipher function.  The reason
is that these are the values passed by EVP_*Final, and some of the
backend cipher functions do check for these to see if a "final" call
is made.
