d6c2285d7c update gradle to 6.1.1
somewhat arbitrary version selection, but this matches what's currently
in use in ExoPlayer in the dev-v2 branch

fixes:
FAILURE: Build failed with an exception.

* What went wrong:
Could not determine java version from '11.0.9.1'.

and removes the wrapper task as this is predefined in later versions:
Build file '/home/jzern/external/libwebp/build.gradle' line: 437

* What went wrong:
A problem occurred evaluating root project 'libwebp'.
> Cannot add task 'wrapper' as a task with that name already exists.

something fast enough.

c6d1db4b36 fix Android standalone toolchain build
add a check for cpu-features.h and rework some of the ifdef's around
android + neon. for android builds with cpu-features enabled the
*_neon.c files will still need to be flagged correctly (with e.g.,
.c.neon in Android.mk) to properly build them.

8acb4942f7 Remove the argb* files.
Half of the functionality was duplicated.
The rest is about the alpha channel handling so we
might as well put it in the appropriate file.

03f40955a3 img2webp: convert a sequence of images to an animated webp
Usage:

  img2webp [file-level options] [image files...] [per-frame options...]

File-level options (only used at the start of compression):
 -min_size ............ minimize size
 -loop <int> .......... loop count (default: 0, = infinite loop)
 -kmax <int> .......... maximum number of frame between key-frames
                        (0=only keyframes)
 -kmin <int> .......... minimum number of frame between key-frames
                        (0=disable key-frames altogether)
 -mixed ............... use mixed lossy/lossless automatic mode
 -v ................... verbose mode
 -h ................... this help

Per-frame options (only used for subsequent images input):
 -d <int> ............. frame duration in ms (default: 100)
 -lossless  ........... use lossless mode (default)
 -lossy ... ........... use lossy mode
 -q <float> ........... quality
 -m <int> ............. method to use

example: img2webp -loop 2 in0.png -lossy in1.jpg
                  -d 80 in2.tiff -o out.webp
