We shouldn't violate the requirement that the key identifier can be
reused. In practice, a key manager may destroy a key that's in use by
another process, and the privileged world containing the key manager and
the crypto service should not be perturbed by an unprivileged process.
With respect to blocking, again, a key manager should not be blocked
indefinitely by an unprivileged application.
These are desirable properties even in the short term.

The Docker container used for the CI has Git version 2.7.4 which
does not support the "git branch --show-current" command since this
was added in version 2.22.
Therefore this commit adds an alternative version for old Git versions.

The support for the PSA crypto driver interface
is not optional anymore as the implementation of
the PSA cryptography interface has been restructured
around the PSA crypto driver interface (see
psa-crypto-implementation-structure.md). There is
thus no purpose for the configuration options
MBEDTLS_PSA_CRYPTO_DRIVERS anymore.

- Update for the new hashes strategy, in part by adding references to
md-cipher-dispatch.md
- General update about the status of things since the last update

- Support for PSA_CRYPTO_CLIENT without PSA_CRYPTO_C is out of scope for
now but might be added later (the architecture supports that).
- While we're using a void pointer for md_ctx, we don't need a union
here; the union will be useful only if & when we remove the indirection.

Now that the script only makes before-after comparison, it no longer
makes sense to ignore some test suites.

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.

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.
