fuzz: Fix FUZZ_malloc_rand() to return non-NULL for zero-size allocations
The FUZZ_malloc_rand() function was incorrectly always returning NULL for
zero-size allocations. The random offset generated by
FUZZ_dataProducer_int32Range() was not being added to the pointer variable,
causing the function to always return (void *)0.

Previously, parallel_compression would only handle each job's results
after ALL jobs were successfully queued. This caused all src/dst

It also polled to check whether a job completed, which is racy without
any memory barrier.
Now, we flush results as a side effect of completing a job. Completed
frames are placed in an ordered linked-list, and any eligible frames
are flushed. This may be zero or multiple frames, depending on the
order in which jobs finish.
This design also makes it simple to support streaming input, so that
is now available. Just pass `-` as the filename, and stdin/stdout will
be used for I/O.

lib: zstd: export API needed for dictionary support
Patch series "zram: introduce custom comp backends API", v7.
This series introduces support for run-time compression algorithms tuning,
so users, for instance, can adjust compression/acceleration levels and
provide pre-trained compression/decompression dictionaries which certain
algorithms support.
At this point we stop supporting (old/deprecated) comp API. We may add
new acomp API support in the future, but before that zram needs to undergo
some major rework (we are not ready for async compression).
Some benchmarks for reference (look at column #2)
