Rewrite CHANGES to add some commentary about the "pic" option

 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 "disable-dynamic-engine".

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

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

     without having to build shared libraries and vice versa.  This

     only applies to the engines in engines/, those in crypto/engine/

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

     Building dynamic engines is enabled by default; to disable, use

     the configuration option "disable-dynamic-engine".

     The only requirements for building dynamic engines is the

     presence of the DSO module and building with position independent

     code, so they will also automatically be disabled if configuring

     with "disable-dso" or "disable pic".

     The macros OPENSSL_NO_STATIC_ENGINE and OPENSSL_NO_DYNAMIC_ENGINE

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

     object files.  This means other libraries that use routines from

     libcrypto / libssl can be made into shared libraries regardless

     of how OpenSSL was configured.

     If this isn't desirable, the configuration options "disable-pic"

     or "no-pic" can be used to disable the use of PIC.  This will

     also disable building shared libraries and dynamic engines.

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