The current decode_tiles decodes the frame one tile by one tile
and then loopfilter the whole frame or use another worker thread to
do loopfiltering.

|------|------|------|------|
|Tile1-|Tile2-|Tile3-|Tile4-|
|------|------|------|------|

For example, if a tile video has one row and four cols, decode_tiles
will decode the Tile1, then Tile2, then Tile3, then Tile4.
And during decode each tile, decode_tile will decode row by row in
each tile.

For frame parallel decoding, decode_tiles will decode video in row order
across the tiles. So the order will be:
"Decode 1st row of Tile1" -> "Decode 1st row of Tile2"
-> "Decode 1st row of Tile3" -> "Decode 1st row of Tile4"
-> "Decode 2nd row of Tile1" -> "Decode 2nd row of Tile2"
-> "Decode 2nd row of Tile3" -> "Decode 2nd row of Tile4"-> "loopfilter 1st row"

Inline loopfilter has been already handled in vp9_decode_frame().

Fixes the idecoder in the case where:
  cm->error_resilient_mode == 0, and
  cm->frame_parallel_decoding_mode == 0, but
  new_fb->corrupted == 1.

The assert in debug_check_frame_counts fails to
take into account the case of a corrupt frame.

We only used two members from that struct: max_threads and inv_tile_order.
Moving them directly to VP9Decoder struct.

Actually, it would be great to have two separate enums INTRA_MODES and
INTER_MODES in future.

Adds some high-level hooks for profile 2 before further
progress on the implementation.

According to the definitiion in this patch:
1. Profile 2 only supports 10 or 12 bit color but not 8
2. Profile 2 supports all color sampling modes: 444, 422 and 420,
and alpha plane.
3. Profile 3 is currently undefined.

Please consider the definition carefully and suggest modifications
to the definition as needed.

There was a bug with the decoder that if you started the decoder
with more threads than the first frame had tile columns. Afterwards
tried to decode a frame with more tile columns than the first frame,
the decoder would hang. E.g. run vpxdec --threads=4. The first frame
had two tile columns, then the next key frame had 4 tile columns, the
decoder would hang. If you started with 4 tiles and switched to 2
tiles the decoder would be fine. The issue is that the worker the thread
loop is using is stale.

I added a test vector "vp90-2-14-resize-848x480-1280x720.webm" that
exhibited the bug.

Now interp_kernel is obtained when it is really required (based on
mbmi->interp_filter value).
