[PATCH 0/5] Check replacement object type and minor updates

Here is a reroll of the patch forbiding replacing an bject with one of a different type (1/5). It is followed by a documentation update (2/5) and a test (3/5). I also added for good mesure another test (4/5) I came up with while developing the previous test, and another doc update related to what we discussed about creating replacement objects (5/5).

Christian Couder (5):
  replace: forbid replacing an object with one of a different type
  Documentation/replace: state that objects must be of the same type
  t6050-replace: test that objects are of the same type
  t6050-replace: add test to clean up all the replace refs
  Documentation/replace: add Creating Replacement Objects section
