This patch adds code to gldownload to export the image as a dmabuf if requested. The element now exposes memory:DMABuf as a cap feature, and if it is selected, the element exports the texture to an EGL image and then a dmabuf. It also implements a fallback to system memory download in case the exportation failed. https://bugzilla.gnome.org/show_bug.cgi?id=776927
