    Set bounds from the array when iterating mmaps. · 18555734
    Ralph Giles authored
    The mmap allocation code in vp8_dx_iface.c was inconsistent.
    The static array vp8_mem_req_segs defines two descriptors,
    but only the first is real. The second is a sentinel and
    isn't actually allocated, so vpx_codec_alg_priv is declared
    with mmaps[NELEMENTS(vp8_mem_req_segs)-1]. Some functions
    use this reduced upper bound when iterating though the mmap
    array, but these two functions did not.
    Instead, this commit calls NELEMENTS(...->mmaps) to directly
    query the bounds of the dereferenced array.
    This fixes an array-bounds warning from gcc 4.6 on
