If the data is a bitstring or an octet string, instead use the hexstring
of the BER encoding (RFC 4514 Section 2.4)

This refactor is to accomodate future support of numericoid/hexstring
attributetype value pairs.

Due to change in handling non-ascii characters, existing tests had to be
updated to handle the new implementation. New tests and certificates
are added to test the escaping functionality in edge cases.

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.

aca31654e6 removed a sentence with copypasta
refering to PBKDF2 instead of XTS. Restore that comment but fix the
copypasta.

They're included by build_info.h and must not be included directly.
Currently, this only concerns one file: config_psa.h. It's technically a bug
to include it, but a harmless one because that header has already been
included by build_info.h except in configurations where it
effectively had no effect (enabling PSA options with PSA turned off).
We plan to split config_psa.h into multiple headers that are less
independent, which could make the inclusion more problematic.

Since 3.0.0, mbedtls_config.h (formerly config.h) no longer needs to include
config_psa.h or check_config.h: build_info.h takes care of that.

Don't try to include MBEDTLS_PSA_CRYPTO_USER_CONFIG_FILE when
MBEDTLS_PSA_CRYPTO_CONFIG is disabled. This didn't make sense and was an
editorial mistake when adding it: it's meant as an addition to
MBEDTLS_PSA_CRYPTO_CONFIG_FILE, so it should be included under the same
conditions.

They belong here, next to the inclusion of the mbedtls config file. We only
put them in config_psa.h in Mbed TLS 2.x because there was no build_info.h
we could use.

Remove the workaround for psa_key_agreement_internal to
have a shared_secret array always non-zero. The spec is
recently updated so that PSA_RAW_KEY_AGREEMENT_OUTPUT_MAX_SIZE
is always non-zero

New bignum modules are only needed when the new ecp_curves module is
present. Remove them when they are not needed to save code size.
