Subject: [iproute PATCHv2] ipaddress: Allow listing addresses by type
Not sure why this was limited to ip-link before. It is semantically
equal to the 'master' keyword, which is not restricted at all.
The man page and help text adjustments include the 'master' keyword as
well since that is also supported but wasn't documented before.

Note that I am not exactly fond of the changes here. When discovering
that I would have to split the synopsis of 'show' from 'save' and
'flush', I wanted to extend 'flush' to support the added selectors as
well. Sadly this seems to be a can of worms: filter evaluation is spread
over multiple functions, and since 'flush' uses RTM_GETADDR request the
IFLA_* attributes are not available at all. So this is rather a quick
than a clean solution.
