audioconvert: use unaligned loads
...
We collect 4 channels from the source. When the number of channels is
not a multiple of 4, we need to do unaligned reads.
See #2221

audioconvert: pass state to functions
...
Pass some state to convert and channelmix functions. This makes it
possible to select per channel optimized convert functions but
also makes it possible to implement noise shaping later.
Pass the channelmix matrix and volume in the state.
Handle specialized 2 channel s16 -> f32 conversion

mem: align memory to requested alignment
...
Improve the allocators to always align the buffer memory to the
requested alignment
Use aligned read and writes for sse functions and check alignment,
optionally falling back to unaligned path.
Add more tests and benchmark cases
Check and warn for misaligned memory in plugins.
