        [Haiku] Tiny modifications on WebCore files to allow Haiku port.
        https://bugs.webkit.org/show_bug.cgi?id=28128

        * bindings/js/ScriptControllerHaiku.cpp: Style cleanup.
        * loader/CachedFont.cpp: Haiku behaves like Qt, Gtk, or Chromium,
        so many PLATFORM(HAIKU) were added to these functions.
        (WebCore::CachedFont::~CachedFont):
        (WebCore::CachedFont::ensureCustomFontData):
        (WebCore::CachedFont::platformDataFromCustomData):
        (WebCore::CachedFont::allClientsRemoved):
        * page/EventHandler.cpp: Like the mac and Qt port, Haiku doesn't need the
        invertSenseOfTabsToLinks() function.
        * page/haiku/DragControllerHaiku.cpp: Style cleanup.
        * platform/image-decoders/ImageDecoder.h: For image decoding Haiku
        behaves like Cairo or Wx, (not like Skia).
        (WebCore::RGBA32Buffer::getAddr):
        * platform/text/PlatformString.h: Adding the String(BString&) and BString()
        methods specific to Haiku.
        * platform/text/UnicodeRange.h: Haiku needs to include stdint.h.
        * platform/text/haiku/TextBreakIteratorInternalICUHaiku.cpp:
        (WebCore::currentSearchLocaleID): Missing function.
