Atil Raster Provider doesn't work on Linux

[wuma]

It's reported by Autodesk QA: The Raster File Provider implemented based on Autodesk ATIL library cannot render map image. Steps to recreate:

1. Create one connection to Raster data
2. Create one layer.
3. Refresh the layer

Results: Nothing displays.

Expected results: The layer should display correctly.

It's because the dynamic_cast<> failed at below location:

\Server\src\Services\Feature\ServerFeatureUtil.cpp#569 (Method: MgByteReader* MgServerFeatureUtil::GetRaster)

if (type == FdoStreamReaderType_Byte)
{
    FdoPtr<FdoIStreamReaderTmpl<FdoByte> > byteStreamReader =
==> FDO_SAFE_ADDREF(dynamic_cast<FdoIStreamReaderTmpl<FdoByte>*>((FdoIStreamReader*)streamReader));
    CHECKNULL((FdoIStreamReaderTmpl<FdoByte>*)byteStreamReader, L"MgServerFeatureUtil.GetRaster");

    ByteSourceRasterStreamImpl* rasterStream = new ByteSourceRasterStreamImpl(byteStreamReader);
    Ptr<MgByteSource> byteSource = new MgByteSource(rasterStream);
    byteSource->SetMimeType(MgMimeType::Binary);
    byteReader = byteSource->GetReader();
}

Replace dynamic_cast with static_cast will fix this problem.
