scm automatic cleanups.

PDM/VUSB: Provide port/device speed to HCs (and emulated devices).

USB: Beginnings of emulated USB3 devices.

USB: Integrate USB sniffer. Make it possible to specify a file to dump the traffic to when attaching a USB device with VBoxManage

USB: Connecting the dots.

VMM/PDMUsb: add PDMR3UsbQueryLun function which is needed very soon for mounting media at run time in virtual USB DVD drives

VUSB,EHCI,OHCI: Add a method to query whether a device is emulated or not. Required for working saved states when using the MSD device

VMM/SSM: Add support for USB devices

PDM,USB: Add methods to detach and attach drivers to USB devices during runtime, add fFlags parameter to pfnDriver{Detach|Attach} to indicate whether this is a hotplug event or not, use a preconfigured UUID during device instantiation to make removing the device during runtime possible

VMM: Whitespace cleanups by scm.

PDM: init fVMSuspended for USB devices and a todo.

Main,VBoxManage: Implemented IConsole::EmulatedUSB. Removed IMachine::emulatedUSBWebcameraEnabled.

VMM: PDMR3UsbCreateEmulatedDevice

VMM: Suspend and resume reasons.

CFGM: Some smaller PVM/PUVM adjustments.

PDMAsyncCompletion: PVM -> PUVM (one instance), internalize internal APIs where possible (not all because of test cases). API docs lives where the implmentation lives, NOT in headers (IPRT is the exception).

PDM,++: Change APIs used by Main from PVM to PUVM.

PDMUSB: Support attaching virtual USB devices to EHCI.

too long line

Doxygen.

Doxygen, comment typos.

Doxygen.

Set the idTracing members.

PDM: Initial driver chain transformation code (untested).

VMM: -Wunused-parameter

VMM,INTNET: Addressing unused variable warnings.

VMM: typo.

Committed usb_thread.patch with tiny adjustments.

PDM/TM: Implemented USB timers.

VMM: Replace most VERR_VERSION_MISMATCH by more specific error statuses. Translating the errors returned by device, driver and USB device constructors into specific ones for the benefit of old extension pack and misc use of the status.

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

VMM source reorg.
