Main: VBoxNetNAT/VBoxNetDHCP: sometimes it's required to kill the runner process (in case of no Main clients)

Main: NetworkServiceRunner dependencies included in NetworkServiceRunner.h (reverts: r90651,r90653,r90654)

Introduce option "--need-main(-M) on|off" in network services to emphosize whether network service need to establish connection with Main (by default this optiois off).

Space.

Main/NetServiceRunner: Make command line more flexible for adding service specific parameters. XXX: creating final array parameter to RTProcCreate(,,array,,,) need further improvements.

NATNetwork windows build fix. Fixed memory leak in recalculateIpv4AddressAssignments due to confusing string handling and simplified the code there a little (~20 lines shorter). Fixed indentation and some other nits.

Main: re-commit r86967 Main/Network: DHCP server has got the ear in Main, and we able create/describe more complex infrostructures. DHCP server together with Lwip NAT can handle per vm/slot configuration and store them in xml settings. place-holder: Host interface nameserver list, domain name and search strings, I suppose that this functions should be used on initialization stage and then on host configuration change even or directly from event.

backed out r86967,r86968,r86969,r86970,r86971,r86972,r86973,r86975,r86976. will fix build locally.
