These tests check for failures, but can only fail where SIZE_MAX
exceeds some limit (UINT_MAX or UINT32_MAX) and do not fail
in this way otherwise - so guards are needed.

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 =='

The contentInfo field of PKCS7 Signed Data structures can
optionally contain the content of the signature. Per RFC 2315
it can also contain any of the PKCS7 data types. Add test and
comments making it clear that the current implementation
only supports the DATA content type and the data must be empty.
Return codes should be clear whether content was invalid or
unsupported.

If the digest algorithm is not compiled into Mbedtls,
then any pkcs7 structure which uses this algorithm
should fail with MBEDTLS_ERR_PKCS7_INVALID_ALG.
Add test for this case.

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().

Previously, a loop in pkcs7_get_signers_info_set was not
getting covered by tests. This was because when there are
two or less signers, the loop will not execute.
Therefore, add new data files for another signer and use
three signers to generate a new pkcs7 DER file. Add a test
case to make sure that verification is still successfula and
use the test script to create ASN1 errors throoughout the
stucture:
./generate_pkcs7_tests.py ../data_files/pkcs7_data_3_signed.der
This results in the loop being executed.

Previously there were two test functions for verify.
One allowed for the verification of one certificate and
the other allowed for verification of two certificates.
Merge these two functions into one function that can take
any number of certificates as an argument.

Several PKCS7 invalid ASN1 Tests were failing due to extra
data bytes or incorrect content lengths going unnoticed. Make
the parser aware of possible malformed ASN1 data.

Increases %branches covered from 70.4% to 87.7%.
Add a script which serves as documentation for how these new test
cases were generated:

In the future, tests will be added which take in a char buffer
and buflen. Rather than duplicate code, have tests which
read from file and from buffer use the same helper function
