MBEDTLS_CMAC_C dependency is ivalid.
"PEM read (unknown encryption algorithm)" needs MBEDTLS_CIPHER_MODE_CBC dependency as
otherwise this test is failing in test_when_no_ciphersuites_have_mac configuration
because mbedtls_pem_read_buffer() returns a different error (MBEDTLS_ERR_PEM_FEATURE_UNAVAILABLE).

This is done to be able to bild test_psa_crypto_config_accel_hash component where MD5 is only available accelerated (PSA_WANT_ALG_MD5 is enabled and MBEDTLS_MD5_C is disabled) but MBEDTLS_USE_PSA_CRYPTO is disabled.
So the build should not attempt to enable pem_pbkdf1.

Previously these tests depended on the definition from
inside the MD module, which in turn could be 32 or 64
bytes depending on whether MBEDTLS_SHA512_C was
defined. This is unnecessary, so a constant is itnroduced
instead.

Previously the whole .function file had a global dependency on
MBEDTLS_SHA1_C. This hasn't been correct for a long time:
- on principle, dependency declarations in .function files are for
compile-time dependencies;
- in practice, a number of test cases do not depend on SHA-1, as they only
use SHA-256 or SHA-512 - those cases should not be skipped in builds
without SHA-1;
- this was "taken advantage of" to skip dependency declarations for
test cases that only depended on SHA-1.
The previous commit removed the global dependency on SHA1_C; as a result
the test cases that actually depend on SHA-1 were not skipped in builds
without SHA-1. This commit fixes that by adding dependency declarations
where they belong: in the .data file.
All cases compute hashes using MD is available, or PSA otherwise; so
MD_OR_PSA is appropriate here.

Previously MD_C was auto-enabled based on the fact that ALG_RSA_PSS was
requested, but that's no longer the case since the previous commit.
We can fix this in one of two ways: either enable MD_C, or enable all
the PSA_WANT_ALG_SHA_xxx that are needed for test. Go for MD_C because
it's a single line and avoids having to enumerate a list that might grow
in the future.

Internal macros are not present as symbols, visible or usable outside
the compilation unit and it is safe to allow them to have a name without
namespace prefix.
We also allow them to start with lower case letters as some of our
internal macros already have names like that.

When USE_PSA_INIT() failed because lack of seedfile, mbedtls_x509write_csr_free()
crashed when called on an unitialized mbedtls_x509write_csr struct.
This moves mbedtls_x509write_csr_init before calling USE_PSA_INIT(),
which could probably fail, and uses the same flow in x509_csr_check()
and x509_csr_check_opaque().

Unfortunately reusing the new function from the signed constant time
comparison is not trivial.
One option would be to do temporary conditional swaps which would prevent
qualifying input to const. Another way would be to add an additional
flag for the sign and make it an integral part of the computation, which
would defeat the purpose of having an unsigned core comparison.
Going with two separate function for now and the signed version can be
retired/compiled out with the legacy API eventually.
The new function in theory could be placed into either
`library/constant_time.c` or `library/bignum_new.c`. Going with the
first as the other functions in the second are not constant time yet and
this distinction seems more valuable for new (as opposed to belonging to
the `_core` functions.

- We don't check for NULL pointers this deep in the library
- Accessing a NULL pointer when the limb number is 0 as a mistake is the
very similar to any other out of bounds access
- We could potentially mandate at least 1 limb representation for 0 but
we either would need to enforce it or the implementation would be less
robust.
- Allowing zero limb representation - (NULL, 0) in particular - for zero
is present in the legacy interface, if we disallow it, the
compatibility code will need to deal with this (more code size and
opportunities for mistakes)
In summary, interpreting (NULL, 0) as the number zero in the core
interface is the least of the two evils.

When USE_PSA is disabled and ECDSA_DETERMINISTIC is enabled, generating
ECDSA signatures via PK requires use of the hash via the MD layer (in
HMAC-DRBG, used by deterministic ECDSA).
When USE_PSA is enabled, ECDSA signatures via PK go through PSA which
always uses non-deterministic ECDSA, so does not rely on HMAC-DRBG/MD.
The condition used here is slightly too strong, but expressing exactly
the optimal condition seems more effort than it's worth for just 3 test
cases.
