f473d8b44b psa: slot mgmt: Improve psa_search_key_in_slots implementation
In case of a volatile key identifier, no need to check first
the validity of the key identifier, a volatile key identifier
is valid.

Move to a forward search for non-volatile key identifiers as
now key slots with small index are allocated first by
psa_get_empty_key_slot().

07cc04a8ad Updates to PSA crypto library based on review comments
Moved new check_crypto_config.h file from include/psa to library
directory and the file is now included from *.c instead of the
crypto_config.h file. Fixed guards in PSA crypto library based
on review comments for new PSA crypto config features.

7953329d73 Fix another use of uinitialized memory in ssl_parse_encrypted_pms
Complement to 0a8352b4: peer_pmslen is not initialized when decryption
fails, so '|= peer_pmslen' may access uninitialized memory, as indicated
by Frama-C/Eva.

b6f7afcb5c Move check config feature for PSA_WANT
Moved from doing the dependency checks for MBEDTLS_PSA_BUILTIN to

Revised the placement of various new MBEDTLS_PSA_BUILTIN_xxx
guards based on review comments. Corrected guards in psa
test driver to use _ACCEL version instead of _BUILTIN version.
Updated check_config_psa.h to include additional dependency checks
for more algorithms. Renamed some of the new tests to be a little
more clear on the purpose.

adc2ff28b0 Adapt programs to PSA openless APIs
PSA and SSL programs are PSA clients thus should use
psa_key_id_t as the type for key identifiers, not
mbedtls_svc_key_id_t.

As a consequence, PSA, ssl_server2 and ssl_client2
programs cannot compile and must not be compiled if
MBEDTLS_PSA_CRYPTO_KEY_ID_ENCODES_OWNER is defined.
Thus, add MBEDTLS_PSA_CRYPTO_KEY_ID_ENCODES_OWNER
compilation guard to those programs.

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.
