 Changes between 1.0.2f and 1.1.0  [xx XXX xxxx]

  *) Configuration change; it's now possible to build dynamic engines

     without having to build shared libraries and vice versa.  The

     only requirement for building dynamic engines is the presence of

     the DSO module, so configuring "disable-dso" will automatically

     disable dynamic engines.  Dynamic engines are enabled by default,

     and can be disabled with "enable-static-engine".

     This only applies to the engines in engines/, those in

     crypto/engine/ will always be built into libcrypto (i.e. "static").

     The macros OPENSSL_NO_STATIC_ENGINE and OPENSSL_NO_DYNAMIC_ENGINE

     are also taken away from openssl/opensslconf.h, as they are

     irrelevant.

  *) Configuration change; if there is a known flag to compile

     position independent code, it will always be applied on the

     libcrypto and libssl object files, and never on the application

     object files.  This means other libraries that use routines from

     libcrypto / libssl can be made into shared libraries regardless

     of how OpenSSL was configured.

     [Richard Levitte]

  *) Removed JPAKE code.  It was experimental and has no wide use.
