Eric Liu ff51f011d1 [change-namespace] handle constructor initializer: Derived : Base::Base() {} and added conflict detections
Summary:
namespace nx { namespace ny { class Base { public: Base(i) {}} } }
namespace na {
namespace nb {
class X : public nx::ny {
public:
  X() : Base::Base(1) {}
};
}
}

When changing from na::nb to x::y, "Base::Base" will be changed to "nx::ny::Base" and
 "Base::" in "Base::Base" will be replaced with "nx::ny::Base" too, which causes
conflict. This conflict should've been detected when adding replacements but was hidden by `addOrMergeReplacement`. We now also detect conflict when adding replacements where conflict must not happen.

The namespace lookup is tricky here, we simply replace "Base::Base()" with "nx::ny::Base()" as a workaround, which compiles but not perfect.

Eric Liu b9bf1b5b85 [change-namespace] shorten namespace qualifier based on UsingDecl and UsingDirectiveDecl.
Summary:
when replacing symbol references in moved namespaces, trying to make the replace
name as short as possible by considering UsingDecl (i.e. UsingShadow) and
UsingDirectiveDecl (i.e. using namespace decl).

Eric Liu 495b211a6c A clang tool for changing surrouding namespaces of class/function definitions.
Summary:
A tool for changing surrouding namespaces of class/function definitions while keeping
references to types in the changed namespace correctly qualified by prepending
namespace specifiers before them.

Example: test.cc
   namespace na {
   class X {};
   namespace nb {
   class Y { X x; };
   } // namespace nb
   } // namespace na

To move the definition of class Y from namespace "na::nb" to "x::y", run:
   clang-change-namespace --old_namespace "na::nb" \
     --new_namespace "x::y" --file_pattern "test.cc" test.cc --

Output:
   namespace na {
   class X {};
   } // namespace na
   namespace x {
   namespace y {
   class Y { na::X x; };
   } // namespace y
   } // namespace x
