When passed an empty OID, mbedtls_oid_get_numeric_string would read one
byte from the zero-sized buffer and return an error code that depends on
its value. This is demonstrated by the test suite changes, which
check that an OID with length zero and an invalid buffer pointer does
not cause Mbed TLS to segfault.
Also check that second and subsequent subidentifiers are terminated, and
add a test case for that. Furthermore, stop relying on integer division
by 40, use the same loop for both the first and subsequent
subidentifiers, and add additional tests.

The only remaining occurrences of TEST_ASSERT are now pointer comparison,
to NULL or to a reference md_info. That is, the output of the following
command is empty:
grep TEST_ASSERT tests/suites/test_suite_md.function |
egrep -v '= NULL|== md_info|md_info =='

Not only was the size of 100 arbitrary, it's also not great for testing:
using MBEDTLS_MD_MAX_SIZE will get us an ASan error if it ever is too
small.

For all test that want to use a hash, identify it by its numerical type
rather than a string. The motivation is that when we isolate the
MD-light subset from the larger MD, it won't have support for string
identifiers. Do the change for all tests, not just those that will
exercise functions in MD-light, for the sake of uniformity and because
numerical identifiers just feel better.
Note: mbedtls_md_info_from_string is still tested in md_info().
Note: for 2.28 the motivation of upcoming work on MD-light doesn't
apply, but the change is still backported in order keep the two branches
closer to each other (especially the .function file).

The tests here use the test certificates from the cert module where
certificates are needed. Thus, wherever there is a dependency on
MBEDTLS_KEY_EXCHANGE_WITH_CERT_ENABLED, there is also a dependency on
MBEDTLS_CERTS_C.
Fixes `make test` when MBEDTLS_CERTS_C is disabled.

Some of the tests use mbedtls_test_cli_key_rsa_der and
mbedtls_test_cli_crt_rsa_der, and these can be used with

mbedtls_test_psa_setup_key_derivation_wrap() returns 1 for success, 0
for error, so the test here was wrong.
This is just a hotfix in order to avoid a testing gap. Larger issues not
addressed here:
- I don't think we should just exit and mark the test as passed; if
we're not doing the actual testing this should be marked as SKIP.
- Returning 1 for success and 0 for failure is a violation of our
documented coding guidelines. We're also supposed to test with == 0 or
!= 0. Having consistent conventions is supposed to help avoid errors
like this.

psa_cipher_encrypt() and psa_cipher_decrypt() sometimes add a zero offset to
a null pointer when the cipher does not use an IV. This is undefined
behavior, although it works as naively expected on most platforms. This
can cause a crash with modern Clang+ASan (depending on compiler optimizations).
