Gilles Peskine d5b04a0c63 Add a usage parameter to mbedtls_pk_get_psa_attributes 
Let the user specify whether to use the key as a sign/verify key, an
encrypt/decrypt key or a key agreement key. Also let the user indicate if
they just want the public part when the input is a key pair.

Based on a discussion in

Gilles Peskine 32294044e1 Generalize mbedtls_pk_setup_opaque beyond MBEDTLS_USE_PSA_CRYPTO 
It's useful in applications that want to use some PSA opaque keys regardless
of whether all pk operations go through PSA.

Janos Follath 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.

Janos Follath 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.)

Janos Follath 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.

Valerio Setti 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.
