So far all tests use seqno one and only vary the context. Lets add some
tests which vary the seqno too.

Add a test which double checks that fences are in the expected order
after a merge.
While at it also switch to using a mock array for the complex test
instead of a merge.

Introduce a dma_fence_unwrap_merge() macro which allows to unwrap fences
which potentially can be containers as well and then merge them back
together into a flat dma_fence_array.
v2: rename the function, add some more comments about how the wrapper is
used, move filtering of signaled fences into the unwrap iterator,
add complex selftest which covers more cases.
v3: fix signaled fence filtering once more

Add a general purpose helper to deep dive into dma_fence_chain/dma_fence_array
structures and iterate over all the fences in them.
This is useful when we need to flatten out all fences in those structures.
v2: some selftests cleanup, improved function naming and documentation
