repeatedly applied in noisy video. This
mitigates the effect.

visual studio targets do not depend on executables, only the projects
produced.

make[1]: *** No rule to make target `test_libvpx', needed by `.bins'.
Stop.

The current parsing logic of the dumpmachine tuple lacks any arm
cases which means tgt_isa never gets set, so for all arm targets,
we get detected as generic-gnu. Add some basic arm checks here
so the automatic detection logic works.

If you build with --enabled-shared on a Linux arch not explicitly
listed, the configure script will abort because it didn't detect
"linux" in the fallback generic-gnu tuple.
Since this is the fallback tuple and people are passing
--enable-shared, assume the user knows what they're in for.

using large values for the timebase, e.g., {33333, 1000000} could
rollover the timestamp calculation in vp8e_encode as it was not using
64-bit math.

Interleaved loopfiltering with decode. For 1080p clips, up to 1%
performance gain. For 4k clips, up to 10% seen. This patch is required
for better "frame-based" multithreading.

predict_d has become canonical. Remove previous helper function.

The sync interval for the multithreaded encoder was considered as not changing
during the encoding. This is not true if picture size is changed.
The encoder could dead-lock because the main thread and the other threads were
using different sync interval.

After the picture size was changed to a bigger one, the internal memory was
corrupted and multithreaded encoder was deadlocking.
Memory for last frame's MVs, segmentation map and active map were allocated when
the compressor was created (vp8_create_compressor). Buffers need to be
reallocated when picture size is changed, so, the allocation was moved to
vp8_alloc_compressor_data, which is called every time the picture is resized.

The ambient qp and active worse/best qp were reset for every frame
when temporal layers is on. This change removes this reset.
As this affects the target size for forced key frames
(it will actually lower the size somewhat), we increased the
inital boost factor to compensate.

SAD returns unsigned values. Make all the declarations the same.
Remove bestsad initialization and check. It is always set to the
result of a SAD call so it will never remain UINT_MAX
Use ja instead of jg to test unsigned comparison instead of signed.
Update test.

Precalculated block ptrs do not need updates during encoding.
Set these at init stage.
Moved the allocation of 'mt_current_mb_col' (last encoded MB on each
row) to vp8_alloc_compressor_data(), so that it is correctly
reallocated when frame size is changing.

Added drop_frame support in multi-resolution encoder.
If one frame is dropped at a lower-resolution level, the next
upper-resolution level encoder needs to encode that frame
independently without any lower-resolution level motion
information.
Another issue is that if one frame is dropped at some but not all
resolution levels, a frame after that one may use different set
of reference frames at different resolution levels. This reference
frame asynchronization could degrade motion search precision in
upper-resolution level encoding, which uses lower-resolution level
motion result. This change compares the lower-resolution and upper-
resolution level's reference frames. If they are not the same, the
upper-resolution level encoder can not use lower-resolution level
motion result.
