Time stamps are useful when the document gets shared around, but they
tend to lead to merge conflicts.

PSA_WANT_xxx is useful regardless of how the symbols are defined:
explicitly (with MBEDTLS_PSA_CRYPTO_CONFIG) or implicitly (without
MBEDTLS_PSA_CRYPTO_CONFIG).

Without MBEDTLS_PSA_CRYPTO_CONFIG, PSA_WANT_xxx needs to be defined,
for the sake of code that calls the PSA API (TLS code, tests, sample
apps).

Proposed specification for conditional inclusion of cryptographic
mechanism through the PSA API in Mbed TLS.
The inclusion of a mechanism is based on a declaration of boolean
symbols by the application. There is a symbol for each key type or
parametrized key type constructor, and for each algorithm or
parametrized algorithm constructor.
This is work in progress, presented for a first design discussion.
