Fixes a problem where global properties don't work with a NULL query.
Specifying an algorithm with a NULL query ignores the default properties.

Upgrading EVP_PKEYs from containing legacy keys to containing provider
side keys proved to be risky, with a number of unpleasant corner
cases, and with functions like EVP_PKEY_get0_DSA() failing
unexpectedly.
We therefore change course, and instead of upgrading legacy internal
keys to provider side internal keys, we downgrade provider side
internal keys to legacy ones. To be able to do this, we add
|import_from| and make it a callback function designed for
evp_keymgmt_export().
This means that evp_pkey_upgrade_to_provider() is replaced with
evp_pkey_downgrade().
EVP_PKEY_copy_parameters() is the most deeply affected function of
this change.

The output C code was made to use ERR_func_error_string() to see if a
string table was already loaded or not. Since this function returns
NULL always, this check became useless.
Change it to use ERR_reason_error_string() instead, as there's no
reason to believe we will get rid of reason strings, ever.
To top it off, we rebuild all affected C sources.

KEYMGMT methods were attached to other methods after those were fully
created and registered, thereby creating a potential data race, if two
threads tried to create the exact same method at the same time.
Instead of this, we change the method creating function to take an
extra data parameter, passed all the way from the public fetching
function. In the case of EVP_KEYEXCH, we pass all the necessary data
that evp_keyexch_from_dispatch() needs to be able to fetch the
appropriate KEYMGMT method on the fly.

EVP_MD_fetch() can be given a property query string. However, there
are cases when it won't, for example in implicit fetches. Therefore,
we also need a way to set a global property query string to be used in
all subsequent fetches. This also applies to all future algorithm
fetching functions.

Remove GMAC demo program because it has been superceded by the EVP MAC one
Reviewed-by: Richard Levitte <levitte@openssl.org>
(Merged from https://github.com/openssl/openssl/pull/7548)
The MAC EVP_PKEY implementations are currently implemented for each
MAC. However, with the EVP_MAC API, only one such implementation is
needed.
This implementation takes into account the differences between HMAC
and CMAC implementations, and observes that all other current MAC
implementations seem to follow the HMAC model.

We currently implement EVP MAC methods as EVP_PKEY methods. This
change creates a separate EVP API for MACs, to replace the current
EVP_PKEY ones.
A note about this EVP API and how it interfaces with underlying MAC
implementations:
Other EVP APIs pass the EVP API context down to implementations, and
it can be observed that the implementations use the pointer to their
own private data almost exclusively. The EVP_MAC API deviates from
that pattern by passing the pointer to the implementation's private
data directly, and thereby deny the implementations access to the
EVP_MAC context structure. This change is made to provide a clearer
separation between the EVP library itself and the implementations of
its supported algorithm classes.
