The fast scaling for 1 pass mode was being used only on the
first frame after resizing event (because resize_scale_num/den
is set to 1 and only changed for first frame following resize event).
Change-Id: I723b63e21823eb858f25f5662d2bbe4f1842e61f
Proper use/update of resize_state and resize_pending to constrain
the total amount of downsizing to be at most one scale down, for now.

There is still an issue relating to one animated test clip with repeat
patterns where this change effectively increase the default maximum
arf interval by +1. This can be examined seperately.

This commit simplifies the intra block boundary condition logic.
It removes the block index from the argument set.

The clamp calls with INT32_MIN and INT32_MAX have no effect at all on
int values passed in, therefore this commit removes those effectless
clamps and also adds more const intermediate results to make the code
more readable.

The encoder gets its dqcoeff from the context tree. In the decoder move
it to directly after MACROBLOCKD.

Even if the recode loop is not enabled for the current frame type
trap the case where the projected size of a a frame is above the
maximum allowed in recode_loop_test()
Change-Id: I453004694b8f8699e3c2a83252e9f83adccdda4e
Changes to allow more use of rectangular partitions at
speeds 1 and 2 for content classed by the first pass as
animation and for blocks near the active image edge.
This has quite a big impact in quality for the animated
test sequence but also hurts encode speed for speed 2.
For other content types the impact on both speed and
quality is small.
Added some plumbing for detection of internal vertical
image edges.

Change speed features / behavior for split mode when there
is an internal active edge (e.g. formatting bars).
Remove some threshold constraints in rd code near the active
edge of the image.
Add some plumbing for left and right active edge detection.
Patch set 5. Limit rd pass through for sub 8x8 to internal active edges.
This takes away any speed penalty for most clips but keeps the enhanced
edge coding for the more critical case of internal image edges

If the pre-selected partition size (from variance partition) is
32x32, also apply nonrd partition search for 32x32 and 16x16 size.
Overall small positive gain in metrics, average ~1%.
Some visual improvement, for lower resolutions.
Change-Id: I69cb425bda94f7d13d34c451ab30e9276335a30e
Adds two new vp9 parameters --min-gf-interval and --max-gf-interval
to enable testing based on frequency of alt-ref frames.
Also adds a unit-test to test enforcement of min-gf-interval.
For both these parameters the default value is 0, which indicates
they are picked by the encoder, based on resolution and framerate
considerations. If they are greater than zero, the specified
parameter is honored.
(Additional note by paulwilkins)
Note that there is a slight oddity in that key frames are also GFs and
considered part of GF only group. However they are treated as not
being part of an arf group because for arf groups the previous GF is
assumed to be the terminal or overlay frame for the previous group.

Added code to reduce the minimum partition size searched
for super blocks at or straddling the edge of the image.
If the first pass has detected formatting bars the "active" edge
may not be the real edge.

Correct the ARF boost calculations to partly discount
inactive or very low energy regions of the image.
Examples (formatting bars and 0 energy areas of animated clips).
