tests: use sha256line.py instead of /dev/random in test-censor.t (issue6858)
Sometimes the systems that run our test suite don't have enough entropy and
they cannot produce target file of the expected size using /dev/random, which
results in test failures. Switching to /dev/urandom would give us way more
available data at the cost of it being less "random", but we don't really need
to use entropy for this task at all, since we only care if the file size after
compression is big enough to not be stored inline in the revlog. So let's use
something that we already have used to generate this kind of data in other
tests.

tests: make sha256line.py available for all tests
This was previously only used in test-revlog-delta-find.t, but it will be
useful (and used) in other tests that might need to generate
poorly-compressible files.

delta-find: pass the full deltainfo to the _DeltaSearch class
Having more information is better, so we pass it directly.

delta-find: move sparse-revlog pre-filtering in the associated class
Lets move the specialized code in the specialized class.

delta-find: split the _DeltaSearch class in two
We now have things sliced small enough to have two class that use different
`_iter_groups` implementation to encode their different logic.
The filtering code remains to be moved, but I would rather keep this changeset
simple and move them in the next.

delta-find: finish reworking the snapshot logic and drop more layer
The refining logic only applies to the snapshot logic, and this is now all
contained in a dedicated method.
Along the way, we drop the refined_groups // raw_groups layer as they no longer
make sense. The result is a more explicit `iter_groups` method.
This conclude the splitting and simplification of the groups generation.
We are now ready to dispatch this in more diverse classes.

delta-find: move the base of the delta search in its own function
That logic is complicated enough that is is worth puting in its own function. Another method will be introduced in the next changeset to deal with the actual refining.

delta-find: move the emotion of prev in a dedicated method
After splitting the filtering, and with the `_candidate_groups` layer removed,
we can start splitting the group generation too. This helps to organize this
code and make it easier to modifying the future.
