Gilles Peskine f032fa9d94 Special handling for some always-on or alias symbols
Some symbols don't require a dependency symbol:

* Modifiers such as truncated MAC
* Always-on features such as the raw data key type
* Aliases or special values such as RSA PKCS#1v1.5 raw

I'm not convinced that all of these warrant special handling in the
script, rather than having the expected symbol defined somewhere. But
for now I prefer to minimize changes to the header files.

Gilles Peskine 2d2e924401 Implement basic update of PSA_WANT dependencies
Remove any existing PSA_WANT_xxx dependency. Add PSA_WANT_xxx
dependencies based on the PSA_KEY_TYPE_xxx and PSA_ALG_xxx symbols
used in the test case arguments.

PSA_ECC_FAMILY_xxx and PSA_DH_GROUP_xxx are not implemented yet in the
PSA conditional inclusion mechanism in Mbed TLS, so this script
doesn't handle them yet.

Gilles Peskine c109b37b07 Test MBEDTLS_PSA_CRYPTO_EXTERNAL_RNG
Add two builds with MBEDTLS_PSA_CRYPTO_EXTERNAL_RNG to all.sh:
* full minus all DRBG (validates that PSA can work without any of the
  DRBG modules).
* with MBEDTLS_USE_PSA_CRYPTO and no CTR_DRBG (validates that PSA can
  work without CTR_DRBG, and that it works for USE_PSA_CRYPTO).

The goal is to exercise default/full, with/out USE_PSA_CRYPTO, and
with/out deterministic ECDSA (which requires HMAC_DRBG). The choice of
pairing is rather arbitrary.

Ronald Cron c3623dbc76 State PSA_CRYPTO_KEY_ID_ENCODES_OWNER and USE_PSA_CRYPTO incompatibility
Code under MBEDTLS_USE_PSA_CRYPTO define is PSA client
code intended to use key identifiers of type psa_key_id_t.
Thus the MBEDTLS_PSA_CRYPTO_KEY_ID_ENCODES_OWNER
configuration option is incompatible with
MBEDTLS_USE_PSA_CRYPTO.

State this in config.h and check_config.h.

As a consequence:
. remove MBEDTLS_PSA_CRYPTO_KEY_ID_ENCODES_OWNER from
  the full configuration, as MBEDTLS_USE_PSA_CRYPTO is
  part of it.

. add a new component in all.sh to keep testing the
  library when MBEDTLS_PSA_CRYPTO_KEY_ID_ENCODES_OWNER
  is set.

John Durkop d032195278 Phase 2 support for MBEDTLS_PSA_CRYPTO_CONFIG
This phase adds in support for the following features being
added to the list of features that can be configured in the
include/psa/crypto_config.h header file using the PSA_WANT_ALG_xxx
macros: ECDH, HMAC, HKDF, and RSA. These changes include changes to
the PSA crypto library to use the appropriate new guards that
will allow the feature to be compiled in or out either using
new PSA_WANT_ALG_xxx or the previous MBEDTLS_xxx macros.

For HKDF and HMAC, most of the PSA library code did not have a
specific matching MBEDTLS_xxx macro for that feature, but was instead
using the generic dependent MBEDTLS_MD_C macro. The ECDH and RSA
features more closely aligned with a direct replacement with a similar
macro.

The new tests for RSA, HMAC, and HKDF would normally unset additional
dependent macros, but when attempting to implement that level of
testing it required removal of too many core features like MD_C, PK_C,
ECP_C and other low level features. This may point to additional phases of
work to complete the transition of these features to the new model.
