MEDIUM: threads: Use __ATOMIC_SEQ_CST when using the newer atomic API.

When using the new __atomic* API, ask the compiler to generate barriers.
A variant of those functions that don't generate barriers will be added later.
Before that, using HA_ATOMIC* would not generate any barrier, and some parts
of the code should be reviewed and missing barriers should be added.

This should probably be backported to 1.8 and 1.9.
