Prepare EVP_MAC infrastructure for moving all MACs to providers
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.
