OpenSSL reformat x509/, x509v3/, pem/ and asn1/.

OpenSSL upstream did a bulk reformat. We still have some files that have
the old OpenSSL style and this makes applying patches to them more
manual, and thus more error-prone, than it should be.

This change is the result of running
  util/openssl-format-source -v -c .
in the enumerated directories. A few files were in BoringSSL style and
have not been touched.

This change should be formatting only; no semantic difference.
