[NTOSKRNL] Place INIT_FUNCTION before the return type (#2823) 
(but after 'static' or SAL 2 annotation.)
Follow-up to 71fefa32, which mentions that it's actually required by the compiler in some circumstances.

[NTOS][SDK:LIB] Add a Resources Arbiter library, to be used by bus drivers (acpi, pci), kernel and legacy hal (PIC HAL). (#2471) 2020-04-09 19:41:11 +02:00

[NTOS:PNP] Add set functions for debugging PNP and IO managers. (#2457) 
Useful functions for debugging IO and PNP managers:

PipDumpDeviceNodes() - displays information about a node(s) in the device tree;
PipDumpResourceRequirementsList() - displays information about a Io List;
PipDumpCmResourceList() - displays information about a Cm List

The tree list of devices (DEVICE_NODE structures) is perhaps the main one in the PnP manager. They also store information about the hardware resources required and assigned to devices.
These functions can help with debugging. For example, you can call PipDumpDeviceNodes() before and after device enumeration and compare the resulting information.

For PipDumpDeviceNodes() it is possible to optionally output:
- allocated resources and boot configuration resources
- resources required
- translated resources
It is possible to displays both a single node and the entire tree.
Optionally, you can display child nodes.

The information output format for resource lists is maximally compressed, since often the only debugging port is a monitor.

The DebugLevel parameter allows dumping in two modes:
0 - unconditional;
1 - if NDEBUG is not defined in "debug.c".

[NTOS:PNP] Handle arbitrary subkey name lengths in EnumerateDevices. CORE-15882 
This also makes it necessary to fix a bug in the previous code:
ZwEnumerateKey will not account for space for a null terminator, so to
ensure we have space, we must allocate the additional WCHAR, but not
include it in the buffer size passed to the function.

Pierre Schweitzer ce6488df31
[NTOSKRNL] Add a quick path for FileFsDeviceInformation in NtQueryVolumeInformationFile 
This allows querying volume information without issuing an IRP to the owner device.
The kernel is supposed to already have all the required information to return
to the caller.

Side effect: this allows querying volume information for devices not implementing
IRP_MJ_QUERY_VOLUME_INFORMATION such as null.sys
This fixes opening null device in Python.

Fix based on debugging by Maxim Smirnov in PR #1442
