Some test cases are using encrypted key file, thus have
dependency on low-level block cipher modules (e.g. AES).
This commit adds unencrypted key file so that we could
get rid of those dependencies.

Separate the fits-in-buffer check (*data_length <= data_size) from the
we-think-it's-a-sensible-size check (*data_length <=
MBEDTLS_X509_MAX_DN_NAME_SIZE).
This requires using an intermediate buffer for the DER data, since its
maximum sensible size has to be larger than the maximum sensible size for
the payload, due to the overhead of the ASN.1 tag+length.
Remove test cases focusing on the DER length since the implementation no
longer has a threshold for it.

Fix the expected output in some test cases.
Add a few more test cases to exercise both a payload length around 256 bytes
and a DER length around 256 bytes, since both are placed in a 256-byte
buffer (value of MBEDTLS_X509_MAX_DN_NAME_SIZE).

Due to differing validations amongst X.509 library functions, there are
inputs that mbedtls_x509_string_to_names() accepts, but it produces output
that some library functions can't parse. Accept this for now. Do call the
functions, even when we don't care about their return code: we're ok with
returning errors, but not with e.g. a buffer overflow.

In particular, "X509 String to Names: long hexstring (DER=258 bytes, too long)"
causes a buffer overflow in parse_attribute_value_der_encoded().

The test for outputing a hexstring representation is actually
testing dn_gets, and is tested in test_suite_x509parse.

Converts none ascii to escaped hexpairs in mbedtls_x509_dn_gets and
interprets hexpairs in mbedtls_x509_string_to_names.

This escapes special characters according to RFC 4514 in
mbedtls_x509_dn_gets and de-escapes in mbedtls_x509_string_to_names.
This commit does not handle hexpairs.

Test against a string with no '=' or ',' in it, which previously caused
mbedtls_x509_string_to_names() to return 0.

Treat backslash as a universal escape character: "\n" is a newline,
backslash escapes any non-alphanumeric character.
This affects some test cases that had "\," standing for backslash-comma.
With the new uniform treatment of backslashes, this needs to be "\\,".

- added 2 new certificates: 1 for testing a serial which is full lenght
and another one for a serial which starts with 0x80
- added also proper Makefile and openssl configuration file to generate
these 2 new certificates

The already existing "x509_csr_check()" function is extended in order
to support/test also CSR's extensions. The test is performed by
adding an extended key usage.

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.

Use escape mechanism defined in RFC 1779 when parsing commas and other
special characters in X509 DN values. Resolves failures when generating
a certificate with a CSR containing a comma in subject value.
Fixes#769.
