It's 'compress helper' not 'decomrpess helper' of course.
All my patch series is misnamed by my idiocy!
This is the last one for this evening, this is interesting
because pack_compression_level instead of the usual
zlib_compression_level is used.
The goal of this patch series is to have some
comment before to procede with remaining conversions.
When compression is fully abstarceted out I will go with
decompression (inflate).
At the end of this job perhaps we have something that
allows us to have fun with different compression libraries.
In any case IMHO this patch series is valid 'per se' as a
cleanup and (a lot of) code lines removing.
