Adrian-Ken Rueegsegger 027c5c9dcb x509: Consider authorityKeyIdentifier in issued_by() 
Prior to verifying the cryptographic signature, check if the
authorityKeyIdentifier matches the key ID of the issuing certificate if
it is available.

Tobias Brunner 776433505b x509: Replace problematic calls of chunk_from_chars() for keyUsage extension 
As noted in 8ea13bbc5c newer compilers might optimize out the
assignment leading to invalid values in the keyUsage extension (as the
length was still set, the extension was encoded, just not with the
intended values).

Fixes #3249.

Martin Willi a115f48428 x509: Do not mark generated addrblock extension as critical 
While RFC 3779 says we SHOULD mark it is critical, this has severe side effects
in practice. The addrblock extension is not widely used nor implemented, and
only a few applications can handle this extension. By marking it critical,
none of these applications can make use of such certificates where included
addrblocks do not matter, such as TLS/HTTPS.

If an application wants to make use of addrblocks, that is usually an explicit
decision. Then the very same application obviously can handle addrblocks, and
there is no need for the extension to be critical. In other words, for local
policy checks it is a local matter to handle the extension, hence making it
critical is usually not of much help.

Tobias Brunner 6133770db4 x509: Use subjectKeyIdentifier provided by issuer cert when checking CRL issuer 
Some CAs don't use SHA-1 hashes of the public key as subjectKeyIdentifier and
authorityKeyIdentifier.  If that's the case we can't force the
calculation of the hash to compare that to authorityKeyIdentifier in the CRL,
instead we use the subjectKeyIdentifier stored in the issuer certificate, if
available.  Otherwise, we fall back to the SHA-1 hash (or comparing the
DNs) as before.

Martin Willi c079c098c4 x509: Check return value when signing attribute certificates 
In addition that this lets AC generation fail properly if private key signing
fails, it also fixes an issue when compiling on Windows with MinGW 4.8.1, where
for some reason the attributeCertificateInfo got encoded incorrectly.
