With some provider implementations, there are underlying ciphers,
digests and macs. For some of them, the name was retrieved from the
method, but since the methods do not store those any more, we add
different mechanics.
For code that needs to pass on the name of a cipher or diges via
parameters, we simply locally store the name that was used when
fetching said cipher or digest. This will ensure that any underlying
code that needs to fetch that same cipher or digest does so with the
exact same name instead of any random name from the set of names
associated with the algorithm.
For code that needs to check what kind of algorithm was passed, we
provide EVP_{type}_is_a(), that returns true if the given method has
the given name as one of its names.

The EVP_PKEY MAC implementations had a diversity of controls that were
really the same thing. We did reproduce that for the provider based
MACs, but are changing our minds on this. Instead of that, we now use
one parameter name for passing the name of the underlying ciphers or
digests to a MAC implementation, "cipher" and "digest", and one
parameter name for passing the output size of the MAC, "size".
Then we leave it to the EVP_PKEY->EVP_MAC bridge to translate "md"
to "digest", and "digestsize" to "size".

Quite a few adaptations are needed, most prominently the added code
to allow provider based MACs.
As part of this, all the old information functions are gone, except
for EVP_MAC_name(). Some of them will reappear later, for example
EVP_MAC_do_all() in some form.
MACs by EVP_PKEY was particularly difficult to deal with, as they
need to allocate and deallocate EVP_MAC_CTXs "under the hood", and
thereby implicitly fetch the corresponding EVP_MAC. This means that
EVP_MACs can't be constant in a EVP_MAC_CTX, as their reference count
may need to be incremented and decremented as part of the allocation
or deallocation of the EVP_MAC_CTX. It may be that other provider
based EVP operation types may need to be handled in a similar manner.

EVP_MAC_ctrl is documented to return 0 or -1 on failure. Numerous places
were not getting this check correct.

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.
