[NTOS:SE] Handle the reference logon session of the token
When creating or duplicating an access token object, make sure that the logon session is getting referenced by the token must be inserted onto the logon reference member (a.k.a LogonSession) for proper logon session referencing tracking.

Also when a token object is about to be destroyed or that we are taking away a reference session from it, we must ensure that the referenced logon session data gets removed from the token in question.

[NTOS:SE] Remove redundant commented call on token duplication
When duplicating an access token, the authentication ID is already copied from the existing token to the new one anyway so there's no point on having the commented call still left in the code.

506cee3219 [NTOS:SE] Implement logon session termination notification
Note to SELF and EVERYONE: the commit implements the initial logon session termination notification implementation, the SeMarkLogonSessionForTerminationNotification function, but as it currently stands there are several other tasks to be addressed in the future in order for the logon termination notification to be fully completed. The tasks as of which are.

1. Our SepRmDereferenceLogonSession is not fully implemented, as it doesn't inform the LSA and filesystems of logon deletion notification
2. Implement two worker routines that are actually in charge of such tasks of informing LSA and FSDs
3. Perform logon deletion
4. Do further investigations and check whatever that is left to address, if any

[NTOS:SE] Move SQOS capturing in its own file

[NTOS:SE] Allocate pool memory for security descriptor based on the caller pool type request
We're indiscriminately allocate the pool as non paged all the time, thus further ignoring the pool type parameter of the function.

94054a5735 [NTOS:IO] OpenRegistryHandlesFromSymbolicLink: Use REG_OPTION_NON_VOLATILE
Use REG_OPTION_NON_VOLATILE instead of REG_OPTION_VOLATILE in all ZwCreateKey calls of OpenRegistryHandlesFromSymbolicLink, since the keys created/opened by this function, should be non-volatile (in other words, be saved after reboot).
Also Device Parameters subkey that is created in IoOpenDeviceInterfaceRegistryKey (which uses that routine as well), is non-volatile too, so the parent keys whose contain it, cannot be volatile.
It will fix an error with status 0xc0000181 (STATUS_CHILD_MUST_BE_VOLATILE) occuring during loading kernel mode audio drivers from Windows XP/2003, especially checked (debug) versions, with my IoGetDeviceInterfaceAlias implementation. Also it may fix other error cases.

[NTOS:SE] Assign the control flag bits to the newly created security descriptor
We allocate memory pool for a new security descriptor with specific info filled by the caller but we don't set the control flag bits for the newly allocated descriptor, which is wrong. Originally spotted by Vadim Galyant.

608032bd08 [NTOS:KD64][NTOS:KDBG] Fix spinlocks use
Raise IRQL before entering debugger, so that KeAcquireSpinLockAtDpcLevel works as expected.
 - HIGH_LEVEL since we don't know where we are coming from.

Do not try to read debug symbol from files in KDBG.
 - There is no reason that this works if Mm didn't map it in the first place.

d1f5c31820 [SDK] Add GCC overrides for SAL annotations
GCC has some functions, variables & type attributes which can be used as aliases
for some of the SAL annotations. Although it's not as rich & precise, it's still useful
since we actually enable -Werror on GCC builds whereas we don't use such an option
on MSVC builds.

For now, _Must_inspect_result_ is aliased to warn_result_unused attribute.

[NTOS:PS] Fix several issues within info classes in AMD64 build
ProcessUserModeIOPL, ProcessWow64Information and ThreadZeroTlsCell classes fail on AMD64 build because of wrong IQS values assigned to them. Also explicitly tell the compiler that ProcessUserModeIOPL is strictly for x86 as user mode I/O privilege level is 32-bit stuff.
In addition to that, implement IQS_NO_TYPE_LENGTH macro which it'll be used for classes such as ProcessUserModeIOPL where type length is not required and that it should be 0. With that said, we indirectly fix a size length mismatch issue with ProcessUserModeIOPL on 32-bit of ReactOS as well.
