A previous change of this function introduced a fragility when the
destination happens to be the same as the source. Such alias isn't
recommended, but could still happen, for example in this kind of code:
X509_NAME *subject = X509_get_issuer_name(x);
/* ... some code passes ... */
X509_set_issuer_name(x, subject);

The wrong "set" field was incremented in the wrong place and would
create a new RDN, not a multi-valued RDN.
RDN inserts would happen after not before.
Prepending an entry to an RDN incorrectly created a new RDN
Anything which built up an X509_NAME could get a messed-up structure,

This guards against the name constraints check consuming large amounts
of CPU time when certificates in the presented chain contain an
excessive number of names (specifically subject email names or subject
alternative DNS names) and/or name constraints.
Name constraints checking compares the names presented in a certificate
against the name constraints included in a certificate higher up in the
chain using two nested for loops.
Move the name constraints check so that it happens after signature
verification so peers cannot exploit this using a chain with invalid
signatures. Also impose a hard limit on the number of name constraints
check loop iterations to further mitigate the issue.
Thanks to NCC for finding this issue. Fix written by Martin Kreichgauer.

return true for characters > 127. I.e. they are allowing extended ASCII
characters through which then cause problems. E.g. marking superscript '2' as
a number then causes the common (ch - '0') conversion to number to fail
miserably. Likewise letters with diacritical marks can also cause problems.
If a non-ASCII character set is being used (currently only EBCDIC), it is
adjusted for.
The implementation uses a single table with a bit for each of the defined
classes. These functions accept an int argument and fail for
values out of range or for characters outside of the ASCII set. They will
work for both signed and unsigned character inputs.

Make signature security level checking more flexible by using
X509_get_signaure_info(): some signature methods (e.g. PSS, ED25519)

Many signature types define the digest and public key type by a single OID
such as ecdsa_with_sha256.
Some types (RSA-PSS for example) use a single OID to indicate the signature
scheme and additional parameters are encoded in the AlgorithmIdentifier.
Add an X509_SIG_INFO structure to contain details about the signature type:
specifically the digest algorithm, public key algorithm, security bits and
various flags. This supports both existing algorithms and more complex
types.
Add accessors for the structure and a special case that retrieves signature
information from a certificate.
