Rich Salz 04e62715db Introduce ASN1_TIME_set_string_X509 API
Make funcs to deal with non-null-term'd string
in both asn1_generalizedtime_to_tm() and asn1_utctime_to_tm().

Fixes issue #3444.

This one is used to enforce strict format (RFC 5280) check and to
convert GeneralizedTime to UTCTime.

apps/ca has been changed to use the new API.

Test cases and documentation are updated/added
