d8cdb89fb0 [NTOSKRNL] Overhaul Cc and Mm relationship 
Previously, when creating a file section, Mm requested Cc to cache the file, then Cc would request pages from Mm, then Mm would request them back to serve its file-mapping role
Now, Mm does it all by itself. If file cahcing is requested by the FS driver, then Cc creates a file mapping and uses that to serve its purpose.

This is a rewrite of Cc

[NTOSKRNL] Sync some INIT_FUNCTION (#2824) 
- Sync some INIT_FUNCTION with how they are used and what is already
  specified in the headers.
Addendum to commit 85e5b5be (r49445).

- KdbpGetCommandLineSettings(): Remove INIT_FUNCTION.
Fix MSVC 2015 x86 custom build:
"...\ntoskrnl\kdbg\kdb.c(1699): error C2983: 'KdbpGetCommandLineSettings': all declarations must have an identical __declspec(code_seg(...))"

And may also fix obscure bugs when entering into the KDBG debugger.

[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

[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).
