This adds public constructors which take a CoglBitmap to all primitive texture types. This constructor should be considered the canonical constructor for initializing the texture with data because it should be possible to wrap any type of data in a CoglBitmap. Having at least this single constructor avoids the need to have an explosion of constructors such as new_from_data, new_from_pixel_buffer and new_from_file etc. The already available internal bitmap constructor for CoglTexture2D has had its flags parameter removed under the assumption that flags do not make sense for primitive textures. The meta constructor cogl_texture_new_from_bitmap now just explicitly calls set_auto_mipmap after constructing the texture depending on the value of the COGL_TEXTURE_NO_AUTO_MIPMAP flag.
