Fix a bug, where a failure to allocate the kernel mode WINDOW_OBJECT would cause a page fault, because the WND was still allocated, but never initialized, and Wnd->rpdesktop was then dereferenced to free the WND again.

- More fixes to VDM PUSH/POPF code:
- When doing a 32bit push, don't store the flags 2 bytes off
- Recalculate HardwareEsp, by substracting the segment part, instead of truncating the flat pointer to 16 bit.

[NTOSKRNL]: Implement CmdPutString command, and add log message types. Kernel version/build, processor, and RAM, now appear on EMS screen (due to InbvDisplayString), as well as loaded drivers. Next steps are to support log entries and a flag to route debug output (a ReactOS-specific feature request).

[NTOSKRNL]: Implement basic Headless support in the kernel. Implement missing InbvPort routines based on WinLdrPort (using cportlib). Add header for Hdl. Terminal initializes now on COM2. Added misisng code to InbvDisplayString to also display on Headless Terminal (requires unimplemented HeadlessDispatch). Next steps are to implement the kernel log buffer, and HeadlessCmdPutString to see boot strings.

- On completion of SCE request, create and queue a workitem to handle:
Clearing the connection flag and reset the port.
Create and initialize the USB device by calling the appropriate roothubs Direct Call Interface.
Create the device object, get the device descriptors and the serial and product strings of the USB device to be used for creating the deviceid and instanceid.
- Format code and misc changes.
- Together with the usbehci driver, ReactOS at least runs the device installation wizard with the correct device description.

- Dont reset the port in the DPC after device is connected, the usbhub driver will do that later.
- Implement ResetPort and create a timer to call a DPC to coplete the SCE request.
- Dont queue all URBs and have seperate thread complete them as other URBs may still need to be completed.
Instead only queue the SCE request and complete it when a usb device is connected or reset.
- Implement RemoveURBRequest and fix bugs in URB_FUNCTION_GET_DESCRIPTOR_FROM_DEVICE.
- For IOCTL_INTERNAL_USB_GET_ROOTHUB_PDO dont return the FDO in Argument2 as no upper level driver should be communicating with the FDO of the roothub.
- Dont assign the usb device an address when initialized as the hub driver will do it later.

[FREELDR]: Implement support for /redirect=comX (usebiossettings not yet supported) and /redirectbaudrate. Uses cportlib. Tested, serial output works and kernel reports "Headless support is not yet implemented". Future revisions should support ACPI SRT for PCI-based serial ports on server systems.

[NTOS]: Using IsBadRead/CodePtr, it's possible for user-mode code to generate cases where we *think* this is an ARM3-managed piece of VA, which will always have a VAD (Since we only manage the PEB/TEB), but actually it's a bogus VA-looking address that is actually invalid. We didn't consider this case. We now implement the same code Windows normally would also handle, when the VA is bogus, and accept that no VAD might be found, so MM_NOACCESS is returned and thus an access violation sent to the caller. In the case of the IsBad...Ptr, this function would then return TRUE, as the caller expects.

- Part support for resource change with PciComputeNewCurrentSettings... full support for PciSetResources, PciUpdateHardware, PcipUpdateHardare
- IRP_MN_START_DEVICE for PDO (PciPdoIrpStartDevice) implement
- PciNextPartialDescriptor, PciDebugPrintCmResList, PciDebugPrintPartialResource helpers implement
- Now full PDO support almost done, PCIX driver ready for test
- Thanks to cgoodman assert fix
- PnP forever recursion in enumerate, must fix to finish
- Goodbye sir_richard, nice to have you

- Daniel Zimmermann: Fix POPF bugs in VDM mode, namely truncation of the stackpointer to 16 bit and setting proper flags in the trapframe eflags register. This fixes problems with videocards calling int 0x10 VESA BIOS extension.
See issue #5608 for more details.

- Add missing call to HalInitPnpDriver during I/O manager initialization. The HAL PnP driver was never getting initialized.
- Add HAL callback for HalInitPnpDriver. It's going to be needed in future for eVb's PCI driver to fully work (interrupt translation, among other things).

- Modify IopCreateDriver to accept the PLDR_DATA_TABLE_ENTRY instead of the DllBase and SizeOfImage from this structure.
- Set the DriverObject->DriverSection before calling the DriverEntry routine.
- If the DriverEntry routine fails then set the DriverObject->DriverSection back to NULL so that IopDeleteDriver doesnt attempt to unload the ModuleObject, after it was already unloaded by the caller.

- Fix a code typo which led to a security issue when the XOR algorithm for the system cookie might actually yield zero. Now it's going to loop as long as the cookie is 0, attempting to generate a non-zero one.

- Fix a strange bug where we were only setting SharedUserData->TestRetInstruction conditionally only if lookup failed - it should be set on success. Also, bail out if the lookups failed.

- Fix incorrect POOL_TYPE allocation in IoInvalidateDeviceRelations. This function can be called at DISPATCH_LEVEL, which requires NonPagedPool POOL_TYPE.

- Giannis Adamopoulos: Only dereference a class if it's valid, should fix Heroes 3 crash.

- Rename KINTERRUPT_DISPATCH_CODES to DISPATCH_LENGTH, as it is in PSDK.
- Enhance NMI debug support.
- Change some comments to standard ReactOS commenting style.

- Fix release build, part 2. Further improvement to gDebugChannels would be to convert them to a DECLARE_DEBUG_CHANNEL-alike macro.
