  +) Make it possible to replace the underlying "ERR" functions such that the

     global state (2 LHASH tables and 2 locks) is only used by the "default"

     implementation. This change also adds two functions to "get" and "set"

     the implementation prior to it being automatically set the first time

     any other ERR function takes place. Ie. an application can call "get",

     pass the return value to a module it has just loaded, and that module

     can call its own "set" function using that value. This means the

     module's "ERR" operations will use (and modify) the error state in the

     application and not in its own statically linked copy of OpenSSL code.
