Fix BN error reporting

Commit ed57f7f935 implemented the macro ERR_raise and updated err.h to use
it. A typo in err.h means that errors in the BN library are mistakenly
attributed to the RSA library.

This was found due to the following error appearing in a travis log:

        BNerr(BN_F_BN_MOD_INVERSE_NO_BRANCH, BN_R_NO_INVERSE);

ERR: re-use the err_data field when possible

To deallocate the err_data field and then allocating it again might be
a waste of processing, but may also be a source of errors when memory
is scarce.  While we normally tolerate that, the ERR sub-system is an
exception and we need to pay closer attention to how we handle memory.

This adds a new err_data flag, ERR_TXT_IGNORE, which means that even
if there is err_data memory allocated, its contents should be ignored.
Deallocation of the err_data field is much more selective, aand should
only happen when ERR_free_state() is called.

test/evp_test.c: modify to use OSSL_PROVIDER_available()

This changes the stanza format used so far.  Some test stanza had the
following line, only possible for digests:

    Legacy = 1

These have been traded for the following:

    Availablein = legacy

That line is globally available in all test stanza and can be used to
tell what providers a certain algorithm may be available in.  Only one
provider needs to match, so one might have something like this for
some tests:

    Availablein = default fips

This means that one of those providers must be available for the test
stanza to be performed.

If the providers mentioned for a stanza aren't available, the test is
skipped.
If this line isn't used in a stanza, the algorithm is assumed to be
available unconditionally (either by fallback providers, or providers
loaded by the config file).

Add functions to see if a provider is available for use.

Public function OSSL_PROVIDER_available() takes a library context and
a provider name, and returns 1 if it's available for use, i.e. if it's

Internal function ossl_provider_activated() returns 1 if the given
OSSL_PROVIDER is activated, otherwise 0.

Don't generate an unnecessary Diffie-Hellman key in TLS 1.3 clients.

tls_parse_stoc_key_share was generating a new EVP_PKEY public/private
keypair and then overrides it with the server public key, so the
generation was a waste anyway. Instead, it should create a
parameters-only EVP_PKEY.

(This is a consequence of OpenSSL using the same type for empty key,
empty key with key type, empty key with key type + parameters, public
key, and private key. As a result, it's easy to mistakenly mix such
