+ Changing "in <hyp>" to "in <clause>" (no at, no InValue and no

InType) for  "replace <c1> with  <c2>" and "replace c1"  and partially
for  "autorewrite".   
+ Adding  a  "by  tactic"  optional argument  to "setoid_replace".  
+ Fixing bug #1207
+ Add new test files for syntax change and updating doc.
+ Moving argument tactic extensions from extratactics to extraargs
