The "suncc" atomics implementation uses a suncc specific memory
barrier, but also relies on a few atomic functions from atomic.h,
that are not suncc specific but specific to solaris. This made
the current implementation fail on suncc on linux.

Add simpler names and a shorthand for native atomics (as opposed to
pthreads fallback).

We used to use 'filtergraph' or 'filter graph' randomly.

'filtergraph' was chosen due to having 57 occurrences in
the documentation, whereas 'filter graph' had only 19.
