* Extend cert_write example program by options to set the CRT version
and the message digest. Further, allow enabling/disabling of authority
identifier, subject identifier and basic constraints extensions.
* Add explicit warnings for the use of MD2, MD4, MD5, SHA-1, DES and ARC4
throughout the library.
