There is a issue currently related to CMAC TDES, when the new provider
is tested against older branches.
The new strict check caused backwards compatibility issues when
using old branch with the new FIPS provider.
To get around this CMAC now allows TDES by default, but it can be either
enabled via config or a settable. (i.e it uses an indicator)
Where the TDES cipher check can be done turned out to be problematic.
Shifting the check in the TDES cipherout of the init doesnt work because
ciphers can run thru either final or cipher (and checking on every
cipher call seemed bad). This means it needs to stay in the cipher init.
So the check needs to be done in CMAC BEFORE the underlying TDES cipher
does it check.
When using an indicator the TDES cipher needs its "encrypt-check" set
so that needs to be propagated from the CMAC object. This requires
the ability to set the param at the time the cipher ctx is inited.
An internal function was required in order to pass params to CMAC_Init.
Note also that the check was done where it is, because EVP_Q_mac() calls
EVP_MAC_CTX_set_params(ctx, cipher_param)
EVP_MAC_CTX_set_params(ctx, params)
EVP_MAC_init(ctx, key, keylen, params)
Where the second call to set_params would set up "encrypt-check" after
"cipher".

The macro for "block-size" is OSSL_MAC_PARAM_BLOCK_SIZE, and this
parameter is not settable. Refer to the "customization string" rather
than the "custom value" (in the Blake2 spec, this is called the
personalization string).

The idea being that doc/man7/provider-mac.pod is for provider authors,
while provider users find the documentation for each implementation in
doc/man7/EVP_MAC-*.pod, the documentation of parameters wasn't quite
aligned. This change re-arranges the parameter documentation to be
more aligned with this idea.

The commit claimed to make things more consistent. In fact it makes it
less so. Revert back to the previous namig convention.
This reverts commit d9c2fd51e2.

functions are now EVP_MAC functions, usually with ctx in their names.
Before 3.0 is released, the names are mutable and this prevents more
inconsistencies being introduced.
There are no functional or code changes.
Just the renaming and a little reformatting.

Replace the properties default, fips and legacy with a single property
called "provider". So, for example, instead of writing "default=yes" to
get algorithms from the default provider you would instead write
"provider=default". We also have a new "fips" property to indicate that
an algorithm is compatible with FIPS mode. This applies to all the
algorithms in the FIPS provider, as well as any non-cryptographic
algorithms (currently only serializers).

We now describe parameters instead of controls.
Also, since macros like EVP_MAC_CMAC do not exist any more, we rename
the pod files from EVP_MAC_{algo}.pod to EVP_MAC-{algo}.pod. This
allows getting the documentation like this:
man EVP_MAC CMAC
