Changes from v2:
1. factor out common code first and reuse utility
code to resolve 'current' flag.
2. drop supporting 'maximum' flag

New subject: [libvirt] [PATCH v3 1/2] vz: factor out config update flags checks
Actually this is not pure refactoring. Part of common code is
replaced with virDomainObjUpdateModificationImpact and this
a good replacement. It includes removed check of inactive
domain and active flags set. Additionally we resolve
current flag in accordance with current state of domain.
Thus it becames possible to attach/detach devices for
inactive domains if this flag is set.

New subject: [libvirt] [PATCH v3 2/2] vz: implement memory setting functions
Quite straigthforward as vz sdk memory setting function makes
just what we want to that is set "amount of physical memory
allocated to a domain".
'useflags' is introduced for non flag function implementation.
We can't just use combination of flags like "live | config" or
we fail for inactive domains. Other combinations have drawbacks
too.
