hal-common/atomic_ring_buffer: add push_bufs() push_slices()

2023-03-02T03:11:49+00:00

This allows a writer to access all of the free space in the buffer, even
when it's wrapping around.

common: allow atomic ringbuf to fill up to N instead of just N-1.

This allows the ringbuf to be filled up to `N` instead of just `N-1`, using some fun tricks on the indices.

The advantage is better performance: Before, the first write would fill N-1 bytes, The second would write just the 1 byte left before wrapping, then N-2. Then 2, then N-3, and so on. This would result in more smaller chunks, so worse perf. This problem is gone now.
