cogl: Adds experimental CoglVertexArray type This adds a new CoglVertexArray object which is a subclass of CoglBuffer used to hold vertex attributes. A later commit will add a CoglVertexAttribute API which will be used to describe the attributes inside a CoglVertexArray.

Rename CoglVertexArray to CoglAttributeBuffer This is part of a broader cleanup of some of the experimental Cogl API. One of the reasons for this particular rename is to switch away from using the term "Array" which implies a regular, indexable layout which isn't the case. We also want to have a strongly implied relationship between CoglAttributes and CoglAttributeBuffers.

make COGL_FEATURE_VBOS a private feature Cogl provides a consistent public interface regardless of whether the underlying GL driver supports VBOs so it doesn't make much sense to have this feature as part of the public api. We can't break the api by removing the enum but at least we no longer ever set the feature flag. We now have a replacement private feature flag COGL_PRIVATE_FEATURE_VBOS which cogl now checks for internally. Reviewed-by: Neil Roberts <neil@linux.intel.com>

vertex-array: Adds data arg for _vertex_array_new() This adds an optional data argument for cogl_vertex_array_new() since it seems that mostly every case where we use this API we follow up with a cogl_buffer_set_data() matching the size of the new array. This simplifies all those cases and whenever we want to delay uploading of data then NULL can simply be passed.
