Add size limit to X509_NAME structure.

This adds an explicit limit to the size of an X509_NAME structure. Some
part of OpenSSL (e.g. TLS) already effectively limit the size due to
restrictions on certificate size.

See also upstream's 65cb92f4da37a3895437f0c9940ee0bcf9f28c8a, although this is
different from upstream's. Upstream's version bounds both the X509_NAME *and*
any data after it in the immediately containing structure. While adding a bound
on all of crypto/asn1 is almost certainly a good idea (will look into that for
a follow-up), it seems bizarre and unnecessary to have X509_NAME affect its
parent.
