Nathan Froyd 01583602a9 Bug 1207245 - part 6 - rename nsRefPtr<T> to RefPtr<T>; r=ehsan; a=Tomcat
The bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout.  The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.

CLOSED TREE makes big refactorings like this a piece of cake.

 # The main substitution.
find . -name '*.cpp' -o -name '*.cc' -o -name '*.h' -o -name '*.mm' -o -name '*.idl'| \
    xargs perl -p -i -e '
 s/nsRefPtr\.h/RefPtr\.h/g; # handle includes
 s/nsRefPtr ?</RefPtr</g;   # handle declarations and variables
'

 # Handle a special friend declaration in gfx/layers/AtomicRefCountedWithFinalize.h.
perl -p -i -e 's/::nsRefPtr;/::RefPtr;/' gfx/layers/AtomicRefCountedWithFinalize.h

 # Handle nsRefPtr.h itself, a couple places that define constructors
 # from nsRefPtr, and code generators specially.  We do this here, rather
 # than indiscriminantly s/nsRefPtr/RefPtr/, because that would rename
 # things like nsRefPtrHashtable.
perl -p -i -e 's/nsRefPtr/RefPtr/g' \

     ipc/ipdl/ipdl/builtin.py \
     dom/bindings/Codegen.py \
     python/lldbutils/lldbutils/utils.py

 # In our indiscriminate substitution above, we renamed
 # nsRefPtrGetterAddRefs, the class behind getter_AddRefs.  Fix that up.
find . -name '*.cpp' -o -name '*.h' -o -name '*.idl' | \
    xargs perl -p -i -e 's/nsRefPtrGetterAddRefs/RefPtrGetterAddRefs/g'

if [ -d .git ]; then
    git mv mfbt/nsRefPtr.h mfbt/RefPtr.h
else
    hg mv mfbt/nsRefPtr.h mfbt/RefPtr.h
fi

rename : mfbt/nsRefPtr.h => mfbt/RefPtr.h

/**
* Class DOMSVGStringList
*
* This class is used to create the DOM tearoff objects that wrap internal
* SVGPathData objects.
*
* See the architecture comment in DOMSVGAnimatedLengthList.h first (that's
* LENGTH list), then continue reading the remainder of this comment.
*
* The architecture of this class is similar to that of DOMSVGLengthList
* except for two important aspects:
*
* First, since there is no nsIDOMSVGAnimatedStringList interface in SVG, we
* have no parent DOMSVGAnimatedStringList (unlike DOMSVGLengthList which has
* a parent DOMSVGAnimatedLengthList class). As a consequence, much of the
* logic that would otherwise be in DOMSVGAnimatedStringList (and is in
* DOMSVGAnimatedLengthList) is contained in this class.
*
* Second, since there is no nsIDOMSVGString interface in SVG, we have no
* DOMSVGString items to maintain. As far as script is concerned, objects
* of this class contain a list of strings, not a list of mutable objects
* like the other SVG list types. As a result, unlike the other SVG list
* types, this class does not create its items lazily on demand and store
* them so it can return the same objects each time. It simply returns a new
* string each time any given item is requested.
