When a SubjectPublicKeyInfo (SPKI) is decoded into an X509_PUBKEY
structure, the corresponding EVP_PKEY is automatically added as well.
This used to only support our built-in keytypes, and only in legacy
form.
This is now refactored by making The ASN1 implementation of the
X509_PUBKEY an EXTERN_ASN1, resulting in a more manual implementation
of the basic support routines. Specifically, the d2i routine will do
what was done in the callback before, and try to interpret the input
as an EVP_PKEY, first in legacy form, and then using OSSL_DECODER.

The OpenSSL public API function X509_issuer_and_serial_hash() attempts
to create a unique hash value based on the issuer and serial number data
contained within an X509 certificate. However it fails to correctly
handle any errors that may occur while parsing the issuer field (which
might occur if the issuer field is maliciously constructed). This may
subsequently result in a NULL pointer deref and a crash leading to a
potential denial of service attack.
The function X509_issuer_and_serial_hash() is never directly called by
OpenSSL itself so applications are only vulnerable if they use this
function directly and they use it on certificates that may have been
obtained from untrusted sources.

Fix CID 1472833 by removing a codepath that attempts to allocate a
stack if not already allocated, when the stack was already allocated
unconditionally a few lines previously.
Interestingly enough, this additional allocation path (and the comment
describing the need for it) were added in commit
69664d6af0, also prompted by Coverity(!).
It seems that the intervening (and much more recent) commit
d53b437f99 that allowed sk_X509_dup()
to accept a NULL argument allowed the earlier initialization path
to unconditionally allocate a stack, rendering this later allocation fully
redundant.

When X509_ATTRIBUTE_create() receives an invalid NID (e.g., -1), return
failure rather than silently constructing a broken X509_ATTRIBUTE object
that might cause NULL pointer accesses later on. This matters because
X509_ATTRIBUTE_create() is used by API functions like PKCS7_add_attribute(3)
and the NID comes straight from the user.
This bug was found while working on LibreSSL documentation.
