When we're about to close a file (ie, forget everything about it
and release any associated structure), actually delay it.
This allows keep data fresh in memory for faster reuse in case
it would be required. The effective closing will only happen after some time.
For specific operations, this will produce a real speed up in ReactOS.
For instance, with that patch, Winamp starts within seconds, instead of dozen
of minutes.
In most cases, it will bring ReactOS to performances it had before fixing
the huge leak in FastFAT (commit 94ead99) without leaking the whole FS.
For now, due to regressions, this is only activated for files and not
for directories. Once it gets fixed, it will be enabled for both.

For whatever (unknown) reason yet, this stream file object
seems to be deleted when still in use while installing
ReactOS on BtrFS partition, leading to use after free.
So, quick and dirty hack: leak it to prevent deletion.

Multiple "error C4189: '[...]': local variable is initialized but not referenced".
Thanks to Yuntian Zhang, who hinted at this in CORE-11836.

- Implement AcquireSpinlock, ReleaseSpinlock and GetExtendedFunctionTable notifications.
- Implement a bus scan routine, borrowed from scsiport.
Storport and storahci are now able to detect a disk device attached to a Virtual Box AHCI controller.
This avoids race conditions under high IOs and thus corruption on
the FS, or assertions failures in the kernel.
Easily triggered by building ReactOS on ReactOS ;-).
Until now, our support for dirty volumes was totally broken
to a point where, on FAT32 volume, the dirty couldn't even
be written nor read from the disk.
This commit totally rewrites its handling, for both FAT16 and FAT32
so that it's now fully functionnal. Furthermore, it also gets
totally compatible with our vfatlib, and thus, autochk.
Now, on mount, FastFAT will check if the volume is dirty or not, and
autochk will be able to ask for a repair if dirty. vfatlib will
repair the volume and remove the dirty bit. So that, on next
reboot, the volume will be mounted clean.
As a reminder, the dirty bit is set immediately after mounting
the volume, so that, if you crash or have a powercut, autochk
will always attempt to repair your volume (with more or less,
that's FAT!).
If you want to experience without breaking your FAT volume,
just boot, open a cmd prompt and type: fsutil dirty set c:
and reboot!

This is a hack, and totally not the default behavior.
But it will allow autochk locking the boot volume in
order to verify it on boot, in case it would have
been improperly dismounted.

This avoids initializing cache directly on directory
open/create.
The advantage is we reduce the load on cache manager
and on memory manager by avoiding creating everytime
a stream file object, and initializing cache for it.
This will avoid initializing cache for started
applications 'current directory' which is just opened
for having a valid handle but no read/write is performed
in it, by default.
This is a step forward for autochk.
