This can happen when the number of skipped lines is not consistent with
the number of coded lines.

It is breaking support from files with unknown layout.

Some filters need several input frames before producing output.
For these filter, it becomes simpler to return 0 in
request_frame() and let the framework call it again until
output has been produced.

Fixes ticket #2430.

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).
