- Windows requires 16 bytes of response data.
- Add the PLUGPLAY_CONTROL_USER_RESPONSE_DATA type.
- Usetup and Umpnpmgr must fail if NtPlugPlayControl(PlugPlayControlUserResponse) does not return STATUS_SUCCESS.
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

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.
* 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
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).

- Simplify the volume-deletion code in RawCheckForDismount().
- Fixes the OpenCount check in RawClose(): the VCB mutex must be
released when the volume has not been dismounted, either because
OpenCount != 0 or because RawCheckForDismount() returned FALSE.
- Explicitly use VCB_STATE_LOCKED instead of hardcoding its value.
- In IRP_MN_VERIFY_VOLUME handling, lock the volume before playing
with it, and again let the volume be dismounted only if OpenCount == 0
(and the IoDeleteDevice() call is done by RawCheckForDismount()).
This reverts a7c26408 (r53255) and ff75ae1b (r53694), and a hack from 6075ae9a (r46690).
