Changes:

- Changed internal function to escape for XML (was very slow and is now using code from Edi Weitz)

- optimized URL encoding

- locking mechanism for threaded/multiprocessing programs (*LOCKING-FUNCTION*).

*LOCKING-FUNCTION* can be set to a locking function which must accept a function as parameter. The locking function gets called whenever CL-EMB accesses a global hash table. IMPORTANT: The locking function must return the value of the function it calls!

Example: (defvar *emb-lock* (kmrcl::make-lock "emb-lock") "Lock for CL-EMB.")

(defun emb-lock-function (func) "Lock function for CL-EMB." (kmrcl::with-lock-held (*emb-lock*) (funcall func)))

(setf emb:*locking-function* 'emb-lock-function)
