Nathan Froyd e4e2da55c9 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' \
     mfbt/nsRefPtr.h \

     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'

    git mv mfbt/nsRefPtr.h mfbt/RefPtr.h

// stick values like " ok " (with the spaces) in the buttons in an attempt
// to make them look decent. Unfortunately, if they do this the button
// looks way too big in Mozilla. Worse yet, if they do this _and_ set a
// fixed width for the button we run into trouble because our focus-rect
// border/padding and outer border take up 10px of the horizontal button
// space or so; the result is that the text is misaligned, even with the
// recentering we do in nsHTMLButtonControlFrame::Reflow. So to solve
// this, even if the whitespace is significant, single leading and trailing
// _spaces_ (and not other whitespace) are removed. The proper solution,
// of course, is to not have the focus rect painting taking up 6px of
// horizontal space. We should do that instead (via XBL form controls or
// changing the renderer) and remove this.
