14239c6e2e Switching to PSA can break things with MBEDTLS_PSA_CRYPTO_CLIENT 
It's a rare scenario, but it's currently possible: if you use
mbedtls_cipher_xxx() to encrypt the communication between the application
and the crypto service, changing those functions to call PSA will break your
system.

382b34ca84 Work out the hash interface requirements 
Finish working out the RSA-PSS example in terms of what it implies about the
interface. The key takeaway is that a mixed-domain module must support
algorithms if they are available through either interface, and that's all
there is to it. The details of how dispatch is done don't matter, what
matters is only the availability, and it's just the disjunction of
availabilities.

e50f2f1a8e Add mbedtls_mpi_core_ct_uint_table_lookup 
This will be needed for extracting modular exponentiation from the
prototype. The function signature is kept aligned to the prototype, but
the implementation is new. (The implementation of this function in the
prototype has further optimisations which are out of scope for now.)

The function is not reused in the bignum counterpart as it will become
redundant soon.

This function is meant to be static, but doesn't have the qualifier as
it is not used yet and would cause compiler warnings. The
MBEDTLS_STATIC_TESTABLE macro will be added in a later commit.
