UBI: introduce the VID buffer concept
Currently, all VID headers are allocated and freed using the ubi_zalloc_vid_hdr() and ubi_free_vid_hdr() function. These functions make sure to align allocation on ubi->vid_hdr_alsize and adjust the vid_hdr pointer to match the ubi->vid_hdr_shift requirements. This works fine, but is a bit convoluted. Moreover, the future introduction of LEB consolidation (needed to support MLC/TLC NANDs) will allows a VID buffer to contain more than one VID header. Hence the creation of a ubi_vid_io_buf struct to attach extra information to the VID header. We currently only store the actual pointer of the underlying buffer, but will soon add the number of VID headers contained in the buffer.
