VBoxNetNAT, VBoxNetDHCP: use the VirtualBoxClient interface

NAT networks: don't kill VBoxNetDHCP and VBoxNetNAT but send the INATNetworkStartStop event to ask them politely to shutdown

VBoxNetDHCP: Drag kicking and screaming VBoxNetDhcp::m_DhcpServer to NetworkManager::processParameterReqList() so that we can interrorgate it about DHCP options configured via API (though don't do it just yet).

VBoxNetDHCP: keep a pointer to NetworkManager instead of using a global. To minimize churn, convert that global into a singleton. No functional change intended.

NetworkServices/DHCP: use Utf8Str

spaces

VBoxNetDHCP.cpp: G/c nukes trailing whitespaces.

VBoxNetDHCP: extraction of ''configGetBoundryAddress'' function. (todo)

DHCP/NAT and NAT are acting in the same manner: polling for events on main thread and waiting for packets on internal network on RECV thread. DHCP/Host-Only waits for packets on main thread.

VBoxNetDHCP.cpp: G/c: -lines and todo.

VBoxNetDHCP.cpp: adds listener for host DNS change event.

VBoxNetDHCP: G/c -line.

VBoxNetDHCP: usage of exported functions.

VBoxNetDHCP: exposed ''fetchAndUpdateDnsInfo()'' used in listener(not commited yet) and in initialization. Note: scoped out flush and update configuration amnager's cache will be used for auto-syncronization between updates and requests processing in later commits.

VBoxNetBaseService hides all details of internal network implementation and become responsible for supporting receiving loop. Notification of children are done via introduced interface: virtual int processFrame(void *, size_t) = 0; virtual int processGSO(PCPDMNETWORKGSO, size_t) = 0; virtual int processUDP(void *, size_t) = 0; processFrame() and processGSO() might return VERR_IGNORED, to inform base service switch to processUDP() (e.g. for DHCP needs)

DHCP/VBoxNetDHCP.cpp: G/c unused declarations.

DHCP: first-level DHCP request packet processing moved to NetworkManager class. warning [-Wdelete-incomplete].

VBoxNetDHCP: g/c removed #if 0/endif.

NetworkServices: changed the manner network services verify their dependecy on Main.

DHCP: missed part from (r90725)

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).

VBoxNetDHCP. split ::init to ::initWithMain and ::initNoMain. The first step to avoid connection to Main when servicing Host-Only and Internal Network. ::initNoMain() drops connection at fist action. The further improvement will be hint from caller (cmdline parameter whether DHCP need consult Main and listen for changes on Host-side).

VBoxNetBaseService::tryGoOnline: return iprt status code. Adapt VBoxNetDHCP, add check in VBoxNetLwipNAT.

NetServices/DHCP: XML lease serialization/deserialization.

NetworkService/DHCP: refactoring: 1. Client and Lease are use shared data. 2. data moved to closer to implementations and accessible via accessors.

NetworkServices: coding style

VboxNetDHCP: Lease: hides fields to internal data-structure and expose accessor functions. Lease: wasn't intended to be a base class. drop "virtual" from dtor.

VBoxNetDHCP.cpp: warnings [-Wunused-parameter].

NetworkServices: Whitespace (including tabs!) and svn:keywords cleanups by scm.

DHCP + lwip_nat: Domain Name passing on demand.

VBoxNetDhcp::init: temporary com::Utf8Str object is destructed at the end of the statement, leaving pszLo2Off dangling - give it proper lifetime.

VBoxNetDHCP: nits.

VBoxNetDHCP: Fix unsigned vs signed comparison.

NAT/Loopback mapping: changes semantically unrelated symbol ";" with more expressive "=" for map opperation. VBoxManage natnework modify -t nat-test-1 -l "127.0.1.3=8"

lwip-nat: DHCP using system wide definition INET_ADDSTRLEN, on Windows we redefine it to BSD/Posix style.

lwip-nat: DHCP (stringified IP address validation typo) "(pszTerm - pszLo2Off) < 16"

lwip-nat: dhcp missed loop.

vbox-lwip-nat: DHCP maps 127/8 to registered loopbacks or ignore them.

NATNetwork/DHCP: send DNS list to guest.

VBoxNetDHCP: removes session handling. binding and lease expiration control was added.

VBoxNetDHCP: fix

previous r87050, was re-commit of r86970 DHCP becomes Main client, internals changed to let more flexible managment and describing more complex networks (current state, so it should not brake a lot things, but something could stop working). more stuff moved to BaseNetworkService class. and r87051 nukes trailing whitespaces.

NetworkServices/

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

*,IPRT: Redid the ring-3 init to always convert the arguments to UTF-8.

VBoxNetDHCP: do not exit on VERR_INTERRUPTED (#5620)

VMM reorg: Moving the public include files from include/VBox to include/VBox/vmm.

*: spelling fixes, thanks Timeless!

warning

Automated rebranding to Oracle copyright/license strings via filemuncher

intnetinline.h: Changed the prefix to IntNet.

IntNet,++: Implemented sending frames in ring-0 (disabled).

NetworkServices: branding and cosmetical fixes

Networking: Preparing to make the driver return a send buffer to the device emulation.

*: RTGetOpt cleanup related to --help and --version (now standard option). Use RTGetOptPrintError.
