Matt Caswell 864b89ce49 Move EVP_PKEY algorithm implementations into a union
An EVP_PKEY can be used for multiple different algorithm operations.
Only one can be used at a time, so we move those into a union.

Matt Caswell 9c45222ddc Revise EVP_PKEY param handling
We add new functions for getting parameters and discovering the gettable
and settable parameters. We also make EVP_PKEY_CTX_get_signature_md() a
function and implement it in terms of the new functions.

This enables applications to discover the set of parameters that are
supported for a given algorithm implementation.

Matt Caswell dfcb5d29b5 Add the ability to perform signatures in a provider
This makes EVP_PKEY_sign and EVP_PKEY_sign_init provider aware. It
also introduces the new type EVP_SIGNATURE to represent signature
algorithms. This also automatically makes the EVP_Sign* APIs provider
aware because they use EVP_Digest* (which is already provider aware)
and EVP_PKEY_sign(_init) under the covers.

At this stage there are no signature algorithms in any providers. That
will come in the following commits.

Richard Levitte 3ca9d210c9 Refactor how KEYMGMT methods get associated with other methods
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.

Fixes #9592

Richard Levitte 8b84b075ff Adapt DH to use with KEYMGMT
The biggest part in this was to move the key->param builder from EVP
to the DH ASN.1 method, and to implement the KEYMGMT support in the
provider DH.

Richard Levitte 6b9e37246d Add a mechnism to save the name of fetched methods
This will be useful for information display, as well as for code that
want to check the name of an algorithm.  This can eventually replace
all NID checks.

Matt Caswell 35aca9eccb Add the ability to set PKCS#3 DH padding in providers
This also adds the ability to set arbitrary parameters on key exchange
algorithms. The ability to pad the output is one such parameter for DH.

Matt Caswell 94b40fb77c Enable PKCS#3 DH in the providers
The default provider now has support for PKCS#3 Diffie-Hellman so we
switch libcrypto to using providers for that algorithm.
