98a8e8f862 [NTOS:IO] In IopSynchronousCall first check IrpStack->MajorFunction before checking minor 
Minor function indices are not unique, they are subfunctions, so without first checking the major function, they are ambiguous.

[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.

[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

[NTOS] Don't use TAG_IO_NAME when calling ExFreePoolWithTag() for freeing FileObject->FileName.Buffer . 
This may look strange, since this buffer is originally allocated using
the TAG_IO_NAME tag. However, it happens that file-system drivers are
allowed to re-allocate this buffer: this is what the MS' open-sourced
CDFS driver does, see e.g. CdCommonCreate() and CdNormalizeFileNames()
in cdfs/create.c .

This fixes a pool tag mismatch 'mNoI' != 'nFdC' BSOD when resources
are freed when closing a file that has been opened with a relative name
on a CDFS-mounted volume.

[NDK][NTOS] Add global definition of INIT_FUNCTION/INIT_SECTION (#779) 
* Add an NDK header to define INIT_FUNCTION/INIT_SECTION globally
* Use _declspec(allocate(x)) and _declspec(code_seg(x)) on MSVC versions that support it
* Use INIT_FUNCTION on functions only and INIT_SECTION on data only (required by MSVC)
* Place INIT_FUNCTION before the return type (required by MSVC)
* Make sure declarations and implementations share the same modifiers (required by MSVC)
* Add a global linker option to suppress warnings about defined but unused INIT section
* Merge INIT section into .text in freeldr

[NTOSKRNL] Check that caller has the priviliege to unload a driver 
Also, probe the service name when unloading a driver if called from
user-mode. This will avoid that userland applications can trigger an
invalid read in the kernel (and thus, a BSOD).
