Due to a misplaced #endif, the (non-functional) macro definitions were
not properly removed from crypto_compat.h if MBEDTLS_DEPRECATED_REMOVED
was declared.

After a call to psa_get_key_attributes() to retrieve
the attributes of a key into a psa_key_attributes_t
structure, a call to psa_reset_key_attributes() is
mandated to free the resources that may be
referenced by the psa_key_attributes_t structure.
Not calling psa_reset_key_attributes() may result in
a memory leak.
When a test function calls psa_get_key_parameters()
the associated key attributes are systematically
reset in the clean-up part of the function with a
comment to emphasize the need for the reset and make
it more visible.

Rename functions to get a key slot:
. to make their naming more consistent
. to emphasize that those functions set a lock on the
key slot they return to protect it from being wiped
out and re-used while some part of the library
is accessing it.

Move the return of the identifier of a created key from
psa_start_key_creation() to psa_finish_key_creation().
That way in case of creation error, it is less likely to
return the identifier that was temporarily assigned to
the key while trying to create it.

Decrement the slot access count in psa_finish_key_creation()
when the finalization succeeds instead of in functions calling
psa_finish_key_creation(). That way the decrementation cannot
be forgotten and it reduces the code size.

Special handling of volatile key identifiers is not
needed eventually, they can be handled just as
key identifier in the vendor range.

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().

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.

Complement to 0a8352b4: peer_pmslen is not initialized when decryption
fails, so '|= peer_pmslen' may access uninitialized memory, as indicated
by Frama-C/Eva.

Simplify the guards on MBEDTLS_ERROR_C and MBEDTLS_ERROR_STRERROR_DUMMY.
No longer include superfluous headers and definition: platform.h is
only needed for MBEDTLS_ERROR_C; time_t is not needed at all.

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).

There was one lingering MBEDTLS_MD_C that needed to be removed since
it is no longer needed.
