Jérôme Gardou 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] Don't mark VACB dirty on unpin 
This could happen if BCB was marked dirty previously.
Marking VACB dirty on unpin could lead to a double write of
the VACB, even if clean.
Indeed, now that setting BCB dirty leads to marking VACB
dirty, the VACB can be flushed in between by the lazy-writer.
The BCB state is not reset on VACB flush, contrary to the VACB state.
Thus, on unpin even if the VACB was already flushed, we were
setting back the dirty state, leading the VACB to be flushed again.

This could bring a small performance downgrade. Though it remains
limited since this is mostly used for FS metadata.
Possibly it could lead to metadata corruption, but this is likely
less possible.

[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
