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)
