Subject: PFW: Rule handling from CLI

BZ: 15689

These changes enable handling changing the rules for configuration application
from the command line interface.
It is possible to assign a new rule, to display the existing one or to clear
it.
Restriction: like in XML, root rule must be compound.
Syntax is the following:
- Criterion rule expression:
<criterion> <verb> <object>
- Compound rule expression
(All|Any){<content>}
where <content> is a comma separated list of any kind of rules.
Example:
All{Any{SelectedOutputDevice Includes Headphones, SelectedOutputDevice
 Includes Headset}, Any{Mode Is Normal, Mode Is RingTone}}
means the pertaining configuration will be applied when Selected device
includes either Headphones or Headset, while, ate the same time, Mode is
either Normal or RingTone.

Added dumpDomains remote command to show a summary of domains, configurations
as well as their application conditions (tree view).

Removed not anymore necessary guard against deletion of domains or
configurations that contain rules, ad now they're controlled from the CLI.
