CORE: make sure activated fallback providers stay activated

Calling 'OSSL_PROVIDER_available(NULL, "default")' would search for
the "default" provider, and in doing so, activate it if necessary,
thereby detecting that it's available...  and then immediately free
it, which could deactivate that provider, even though it should stay
available.

We solve this by incrementing the refcount for activated fallbacks one
extra time, thereby simulating an explicit OSSL_PROVIDER_load(), and
compensate for it with an extra ossl_provider_free() when emptying the
provider store.

does supply an implementation of the "RSA" keytype.

    EVP_KEYMGMT *rsameth = NULL;

    OSSL_PROVIDER_available(NULL, "default");
    rsameth = EVP_KEYMGMT_fetch(NULL, "RSA", NULL);

For good measure, this also tests that explicit loading of the default
provider won't fail.

bio printf: Avoid using rounding errors in range check

There is a problem casting ULONG_MAX to double which clang-10 is warning about.
ULONG_MAX typically cannot be exactly represented as a double.  ULONG_MAX + 1
can be and this fix uses the latter, however since ULONG_MAX cannot be
represented exactly as a double number we subtract 65535 from this number,
and the result has at most 48 leading one bits, and can therefore be
represented as a double integer without rounding error.  By adding
65536.0 to this number we achive the correct result, which should avoid the
warning.

The addresses a symptom of the underlying problem: we print doubles via an
unsigned long integer.  Doubles have a far greater range and should be printed
better.

RSA: Do not set NULL OAEP labels

As of the previous commit, when a zero-length (string) parameter
is present in the parameters passed to a provider for a given operation,
we will produce an object corresponding to that zero-length parameter,
indicating to the underlying cryptographic operation that the parameter
was passed.  However, rsa_cms_decrypt() was relying on the previous
behavior, and unconditionally tried to call
EVP_PKEY_CTX_set0_rsa_oaep_label() even when the implicit default label
was used (and thus the relevant local variable was still NULL).
In the new setup that distinguishes present-but-empty and absent
more clearly, it is an error to attempt to set a NULL parameter,
even if it is zero-length.

Exercise more caution when setting parameters, and do not call
EVP_PKEY_CTX_set0_rsa_oaep_label() when there is not actually a
label provided.

params: do not ignore zero-length strings

Prior to this commit, if a string (or octet string) parameter
was present but indicated it was zero-length, we would return success
but with a NULL output value.  This can be problematic in cases where
there is a protocol-level distinction between parameter-absent and
parameter-present-but-zero-length, which is uncommon but can happen.

Since OPENSSL_malloc() returns NULL for zero-length allocation requests,
make a dummy allocation for this case, to give a signal that the string
parameter does exist but has zero length.

Following on from the previous commit, add a test to check that we fail

Fail if we fail to fetch the EVP_KEYMGMT

If we failed to fetch an EVP_KEYMGMT then we were falling back to legacy.
This is because some algorithms (such as MACs and KDFs used via an old
style EVP_PKEY) have not been transferred to providers.

Unfortunately this means that you cannot stop some algorithms from being
used by not loading the provider.

For example if you wanted to prevent RSA from being used, you might expect
to just not load any providers that make it available. Unfortunately that
doesn't work because we simply fall back to legacy if we fail to fetch
the EVP_KEYMGMT.

Instead we should fail *unless* the key type is one of those legacy key
types that we have not transferred.
