[PATCH RFC 0/7] Introduce new async/sync compression APIs

[Joonsoo Kim]

Happy New Year!

This patchset is to introduce new compression APIs. It supports async/sync
compression although there is no async compression driver yet. But, async
APIs can be used as front-end to sync compression algorithm. Major change
is that now APIs are stateless. Instead of previous implementation, tfm
objects doesn't embedded any context so we can de/compress concurrently
with one tfm object. Instead, this de/compression context is coupled with
the request. This architecture change will make APIs more flexible.

This is just a RFC so commit description isn't sufficient. If Herbert
confirms that this is what he expect, I will respin the series with proper
commit description and adding more algorithm support.

Thanks.
