  Changed paths:
    M dyninstAPI/h/BPatch_binaryEdit.h
    M dyninstAPI/src/BPatch_binaryEdit.C

  Log Message:
  -----------
  In binary rewriting, when Dyninst needs to load a library,
it does not check whether this library has been loaded before or not.
Dyninst will create multiple binaryEdit objects for one library,
which can cause inconsistent states between these objects.

This fix adds a map to BPatch_binaryEdit to make sure each library
is only loaded once.
