skipSearch - search a skip list.

       list - list to search in.
       key - key to look for.
       plock - place for value lock (or NULL).

       Searches  for  <key> in <list>, and returns value if found, or NULL if not.  If <plock> is non-NULL, then
       the lock returned in <plock> will be associated with the returned value.  Until this lock  is  passed  to
       skipRelease(), the value will not be freed with the freeValue callback (see skipNewList()).

       MT-Level: Safe if <list> thread-safe.

       skipSearch  - search a skip list.

       plock - set to value lock.
