vp8/encoder/rdopt.c:728: warning: pointer targets in passing argument 3
of 'macro_block_yrd' differ in signedness
vp8/encoder/rdopt.c:541: note: expected 'int *' but argument is of type
'unsigned int *'
distortion is signed when calling macro_block_yrd is both other cases,
as well as for RDCOST

warning: implicit declaration of function
'vp8_variance_halfpixvar16x16_[h|v|hv]_neon'
'vp8_sub_pixel_variance16x16_neon_func'
Use the function macro_block_yrd() to calculate error and distortion
in keeping with what is done for inter frames.
The old code was using a variance metric for once case and an
SSE function for measuring distortion in the other case.
The function vp8_encode_intra16x16mbyrd() is no longer used.

The code previously tested cpi->common.refresh_alt_ref_frame
but there are situations where this flag may be set for viewable frames.
The correct test should be !cm->show_frame.

This commit also removes artificial RDMULT cap for low quantizers.
The intention is to address some abnormal behavior of mode selections
at the low quantizer end, where many macroblocks were coded with
SPLITMV with all partitions using same motion vector including (0,0).
This change improves the compression quality substantially for high
quality encodings in both PSNR and SSIM terms. Overall effect on
mid/low rate range is also positive for all metrics, but smaller
in magnitude.

Commit 336aa0b7da incorrectly
declared current_pos as and int, when it should have been
a FIRSTPASS_STATS pointer.

Adjust checking points in motion vector prediction to better cover
possible movements, and get a better prediction. Tests on test
clips showed a 0.1% improvement in SSIM, and no change in PSNR
and performance.

The old 2 pass code estimated error distribution when coding a
forced (by interval) key frame. The result of this was that in some
cases, when allocating bits at the GF group level within a KF
group there was either a glut of bits or starvation of bits at the end
of the KF group.
Added code to rescan and get the correct data once the position of
a forced key frame has been determined.

-For targets with external build systems like visual
studio CC is not set so check_add_cflags will fail.
Only call this function if extra_cflags is set.

vp8cx_mb_init_quantizer was being called for every mode checked
in vp8_rd_pick_inter_mode. zbin_extra is the only value that
really needs to be recalculated. This calculation is disabled
when using the fast quantizer for mode selection.
This gave a small performance boost (~.5% to 1%).
Note: This needs to be verified with segmentation_enabled.

In sub-pixel calculation, xoffset and yoffset mostly take some
specific values. Modified sub-pixel filter functions according to
these possible values to improve performance.

Added code to scan ahead a few frames when we see what
we think is a static scene in the two pass GF loop to see if the
conditions persist.
Moved calculation of decay rate out into a fuunction.

These changes are specifically targeted at fade transitions to
static scenes. Here we want to place a GF/ARF immediately
after the fade and prevent an ARF just before the fade.
Also some code lines and comment lines shortened to 80 chars
while I was there.

Add --extra-cflags as config parameter for user defined extra CFLAGS.
Add -g to asflags when debug enabled for arm targets.

In both vp8_find_next_key_frame and define_gf_group,
motion_pct was initialised at the top of the loop before
next_frame stats had been read in.
This fix sets motion_pct after next_frame stats have
been read.
