[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] Probe parameters in NtAllocateUuids() if called from user-mode 
This will avoid that userland applications can trigger an invalid write in
the kernel (and thus, a BSOD).

Pierre Schweitzer 6ca1c55c6e
[NTOSKRNL] Only allow SYSTEM to call NtSetUuidSeed() 
Also, validate input buffer before attempting any operation on it.
This will avoid userland applications to be able to trigger an invalid
read in the kernel (and thus a BSOD).

Regarding access restriction, see:

[NTOS] Configuration Manager fixes. 
- Rework CmpSetSystemValues() and remove its 1st-stage text-mode setup hack, since a real registry hive will be used for 1st-stage either.
- Lock, then unlock the registry in NtInitializeRegistry when initializing the hives & flusher.
- Call CmpInitializeHiveList() (i.e., initialize the other hives like \Software, \User, \.Default) only when we are not in setup-mode.
