        "no file selected" placeholder text missing from file upload control

        * WebCore.xcodeproj/project.pbxproj:
        * rendering/RenderFileUploadControl.cpp: Remove class
        RenderFileUploadInnerFileBox, rename defaultFilenameNumChars to
        defaultWidthNumChars
        (WebCore::RenderFileUploadControl::RenderFileUploadControl): Call
        RenderBlock constructor instead of RenderFlexibleBox,
        (WebCore::RenderFileUploadControl::setStyle): Remove references to
        m_fileBox.
        (WebCore::RenderFileUploadControl::valueChanged): Call repaint()
        instead of updateIconAndFileName() (which has been removed)
        (WebCore::RenderFileUploadControl::updateFromElement): Remove
        references to m_fileBox, don't call updateIconAndFilename()
        (WebCore::RenderFileUploadControl::maxFilenameWidth): Calculate width
        without using m_fileBox
        (WebCore::RenderFileUploadControl::createButtonStyle): Remove
        now-unnecessary display:box rule.
        (WebCore::RenderFileUploadControl::paintObject): Remove redundant call
        to paintingDisabled() now that Icon::paint() does it, and add code to
        paint the filename directly.
        (WebCore::RenderFileUploadControl::calcMinMaxWidth): Move this method
        out of RenderFileUploadInnerFileBox and into RenderFileUploadControl
        * rendering/RenderFileUploadControl.h: Make RenderFileUploadControl a
        subclass of RenderBlock instead of RenderFlexibleBox, remove
        updateIconAndFilename() method, remove m_fileBox instance variable.
