7a0445cb28 audiomixer: improve sse and sse2 mixer 
Add mixer benchmark.
Improve sse and sse2 mixer function by removin some read/write to the
temporary buffer at the expense of more scattered reads.

371b5a1836 audiomixer: rewrite the mixer functions 
Let the mixer functions accumulate the intermediate results into a
larger size variable and then clamp to the final precission. This avoids
distortions because of intermediate clamping.

Although the access pattern of the reads are no longer sequential, the
writes are sequential and we don't need to read intermediate values.
Together with the avoided clamping this is probably faster overall.

Add a unit test for the various cases.

No changes, just tab-to-space replacement and a little bit of manual
twiddling.

223f20709d meson: replace join_paths(a, b) with a / b 
More readable and from the meson reference manual:
(since 0.49.0) Using the/ operator on strings is equivalent to calling join_paths.
