195c491880 [NTOSKRNL] Mute some good-path log-spam, no functional change 
Now that the Memory Management is a bit more under control again,
and branching releases/0.4.15 is near,
do mute some frequent log-spam that got introduced during 0.4.15-dev'ing
regarding lazy-flushes and MM balancing.
It frequently logged even while being idle.
Slightly improve the headers of the two touched files.
No rocket-science.

[NTOS:CC][NTOS:MM] Add back CcRosTrimCache and add Delay for MM to work. (#5630) 
MM/CC Add back CcRosTrimCache as suggested by Thomas Faber which was removed in 0.4.15-dev-1717-g 	d8cdb89fb0
and call it once in a while also during read-operations.

fixes JIRA issue: CORE-17624 'Cannot copy files > RAMsize anymore using TotalCommander'

We do assume that reboot to be unrelated.

676dc4b441 Revert "[NTOS:MM] Do proper checks & acquire proper locks when sweeping user pages" 
This reverts commit 7c006df7e0.
Note to self: This is what happens when you have too many branch and push the wrong one.

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
