6ae58931d6 Fix decoder resolution change with tiles
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.

4f857bacd2 [BITSTREAM]Fix the scaling calculation
For very large size video image, the scaling calculation may need use
value beyond the range of int. This commit upgrade the value to 64bit
to make sure the calculation do not wrap around INT_MAX.

The change corrected the decoder behavior.

The bug affects only very large resolution video because the scaling
calculation was sufficient for image size smaller than 2^13.

This resolves issue:

64e2597465 Disable update of last_show_frame for existing frame
When showing a previously decoded frame, i.e. when
show_existing_frame=1, the update of the
last_show_frame flag must be disabled.

This is to ensure that the last_show_frame flag
reflects the state of the flag for the immediately
previously decoded frame rather then the value that
was forced to ensure that a previously decoded frame
would be displayed.

This patch also adds a test vector to verify that the
display_existing_frame flag works as expected. Code
for generating the test vector can be found in this
patch:

2424ba3d8b Added a test vector that exercises lpf deltas
From frame 2, the lpf deltas are all cleared for for even frames, and
a set of values are set and used for odd frames. The intention is to
exercise decoding code around lpf delta/update decoding.

a3e919a4ba Added a test vector
The added vector was encoded with aq mode on, with the intent to
exercise the decode code around segment feature.
