2.9.3
Add scomp backend for zlib-deflate compression algorithm.
This backend outputs data using the format defined in rfc1950
(raw deflate surrounded by zlib header and footer).

Hi,
I have a few queries regarding zlib and in general on whether changes
to acomp interface is planned or would be acceptable. Some of these
are from point of view of exporting compression to user space and
utilizing HW implementations.
- A setup api is required to support different configurations; this
was also proposed as part of initial acomp implementations.
- Zlib also supports notion of preset dictionary and for
decompression, history bytes upto window size might be required to be
provided as part of the request. For HW algorithms supporting these
features, the current acomp api's would need to be extended.
- Currently acomp supports operations only in one go, are there plans
to extend acomp beyond this? For hardware algos supporting partial
ops, we will need to add fields like bytes consumed, flush params,ctx
parameter etc.and export to user.
Thanks,
Abed (Cavium)
