Janne Grunau a67124703f ci: update aarch64/armv7a/ppc64le docker images

available in buster.

Janne Grunau c6a08b3aa1 build: avoid meson's symbols_have_underscore_prefix 
Meson's dynamic check is unreliable when additional compiler flags are
passed via CFLAGS. For example '-fprofile-instr-generate' in oss-fuzz'
coverage build. Fixes #370.

Janne GrunauandJean-Baptiste Kempf e616852536 tools: add optional xxh3 based muxer 
The required 'xxhash.h' header can either be in system include directory
or can be copied to 'tools/output'.

The xxh3_128bits based muxer shows no significant slowdown compared to
the null muxer. Decoding times Chimera-AV1-8bit-1920x1080-6736kbps.ivf
with 4 frame and 4 tile threads on a core i7-8550U (disabled turbo boost):

null:  72.5 s
md5:   99.8 s
xxh3:  73.8 s

Decoding Chimera-AV1-10bit-1920x1080-6191kbps.ivf with 6 frame and 4 tile
threads on a m1 mc mini:

null:  27.8 s
md5:  105.9 s
xxh3:  28.3 s

in include/dav1d/ over the previous one in include/. This allows the use
of '#include "version.h"' in dav1d.h. See !592.
