Bug 1451672 - part 16: Rename EditorBase::MoveNode() to EditorBase::MoveNodeWithTransaction() and create EditorBase::MoveNodeToEndWithTransaction() r=m_kato

Browse Source 
This patch renames EditorBase::MoveNode() to
EditorBase::MoveNodeWithTransaction() and redesign its parameters including
replacing a set of container node and offset in it to EditorDOMPointBase.
However, it takes magic number -1 as meaning end of the container.
Therefore, this patch adds MoveNodeToEndWithTransaction() for keeping the
callers simple.
