de0e3e352d Threading design: Update empty slot tracking
Using a dedicated field allows clean separatin between key attributes
and slot state. This allows us to use the same mechanics for attributes
and key content. Which in turn means lower code size and easier
maintenance.

52586895f7 Clarify threading design document structure
Separate design analysis from plans and make the distinction clear
between what is implemented, what is planned to be implemented soon,
what is planned to be implemented in the future, and what is ideas that
are rejected.

(The distinction between the last two categories doesn't have to be
clear, we can't and shouldn't plan that far ahead.)

0385c2815c Tighten thread safety requirements
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.

ccb0344969 test: add GIT alternative commands for older GIT versions
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.

e6e6b75ad3 psa: Remove MBEDTLS_PSA_CRYPTO_DRIVERS configuration option
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.

c9e0ad23c1 Update design document
- 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.
