[PATCH 0/9] add LOG_UNSUPP log type + mark hcalls as unsupp

Hi,

I got a lot of noise trying to debug an AIX guest in a pseries machine when 
running with 
'-d unimp'. The reason is that there is no distinction between features
(in my case, hypercalls) that are unimplemented because we never considered,
versus features that we made a design choice not to implement.

This series adds a new log type, LOG_UNSUPP, as a way to filter the
second case. After changing the log level of existing unsupported
pseries hypercalls, -d unimp was reporting just the ones that I need to
worry about and decide whether we should implement it or mark as
unsupported in our model. After this series there's still one hypercall
thgat is being thrown by AIX. We'll deal with that another day.

I am posting this a little too close of the soft freeze. If we manage
to get it reviewed in time, since it's a debug QoL change that doesn't
break anything, I'd say we take it. 

Also, I didn't find the maintainer for the util/log.c file. Let me know
if I need to CC someone in special for this file.
