Use atomics to protect libovni process state

Multiple threads may attempt to initialize or finalize the process, so
we keep the state stored in an atomic integer to protect against bad
usage.

Make calling ovni_thread_require() optional
...
When only emitting ovni events, there is no need to explicitly require
the ovni model, as libovni will already pre-populate it for the user.

Rebuild ring buffer pointers after injecting events
...
The ring buffer pointers are no longer valid as we may have displaced
events around. The pointers of the affected region are reconstructed by
reading the events again, following their size.

There is a problem in the way we are reading the buffer in nOS-V, which
fails when the ring buffer gets full. This regression test ensures it is
fixed.
