IB/core: an improved infrastructure for uverbs commands

Hi,

Please find a follow up to my previous proposal for a revised extensible command infrastructure [1].

With this new patchset, I'm trying to improve it further.

The main patch, which was sent previously, was cleaned up.

A second patch tightly related to the previous one make "comp_mask" part of the extended command header, as suggested.

The third patch check extended command size: extend commands should take care to not accept more data than the "comp_mask" is describing.

The latest patch is more experimental: it tries to add a common response header to hold the returned "comp_mask" and size of uverbs (eg. core/) and provider (eg. hw/) responses. I'm not really happy of the shape of this one. It's complicated and makes me uncomfortable. But please have a look at it.

Regards.
