- Import cmdcnst.h and vga.h headers from the 'vga_new' VGA Miniport Driver,
that contain definitions related to VGA registers as well as command-stream
functionality.
- Replace a bunch of hardcoded values by their corresponding defintions.
- Replace "Captain-Obvious" comments in VgaIsPresent() with actual
explanations from the corresponding function in 'vga_new'.
- Simplify the VgaInterpretCmdStream() function, based on the
corresponding one from 'vga_new'.
- Use concise comments in the 'AT_Initialization' command stream definition.
- Import the 'VGA_640x480' initialization command stream from 'vga_new'
and use it as the full VGA initialization stream whenever the HAL
does not handle the VGA display (HalResetDisplay() returning FALSE).
Otherwise we just use the 'AT_Initialization' command stream that
performs minimal initialization.
- Remove unused AT_Initialization and other declarations from ARM build.
- VgaIsPresent(): Re-select the memory mode register before playing
around with the sequencer flag. Otherwise the VGA may not be detected
correctly from time to time.
- VidInitialize(): Simplify the initialization loop, reset AddressSpace
to its "default" value of 1 when calling HalFindBusAddressTranslation()
on 'NullAddress'.
Now for each request SenseBuffer is correctly set
and 3 attempts are made to be sure the STALL state is cleared and
the error is in something else.
Remove the usage of UFI_INQUIRY_DATA structure in favor of "standard"
INQUIRYDATA structure from scsi.h

These are required by latest mingw-w64 stl and we are mixing this with our crt headers.
Define _CRT_NO_POSIX_ERROR_CODES in all modules that define their own constants.
Some mice give a logical min/logical max which is the maximum move
that they can provide. Those were wrongly detected as absolute mice,
and mouse pointer was mostly stuck at the upper left corner of the
screen.
Interface between both is not anymore the HidParser_* functions, but
the HidP_* functions and the AllocFunction/FreeFunction/DebugFunctions/
ZeroFunction/CopyFunction.
There is no need to compile our DLLs as shared libraries since we are
managing symbols exports and imports through spec files.
On my system, this reduces the configure-time by a factor of two.
The last parameter of USBPORT_ParseConfigurationDescriptor is a pointer
to a boolean indicating whether any alternate interface settings were
found for the specified interface.
Interpreting it as an alternate setting value, as we did before,
would always override the alternate setting to '1' (if any alternate
descriptors were present), therefore selecting the wrong interface
setting, and possibly causing a buffer overflow on the InterfaceList's
Pipes array.
Found by Special Pool.
There can be other descriptors between the config descriptor and the
first interface descriptor, so we specifically need to check for
the interface descriptor type and skip anything before that.
We also need to guard against bLength == 0, which would cause an
infinite loop, instead of doing a second bDescriptorType check.
We previously only gave the device a hard-coded amount of time to respond,
which could lead to interpreting the contents of uninitialized memory as
a response. This would lead to an unreasonably large number of audio function
groups being detected.
A KSEMAPHORE mirrors what Haiku uses here, though it may not be the optimal
synchronization primitive for this case under Windows.
This protects against crashing in case of faulty/malicious hardware,
but also works around a bug in HDA_SendVerbs that causes it to return
invalid data, thereby suggesting more groups than are actually present.
This will avoid 0-sized allocations, or -1-sized allocations.
So far, it's maxed by hard value stored in TCPIP.sys. I believe
this is not right and would deserve a true fix
This is needed in order to avoid an infinite recursive loop between
disk!UpdateRemovableGeometry() and ntos!IoReadPartitionTable().
This does not happen with NT5+ disk_new.sys because it doesn't call
IoReadPartitionTable() in that situation.

Do not enable it yet, as it doesn't work in ROS for the moment :-(.
Its place in tree is not optimal (it should be with disk/class/etc.),
but I prefer keeping it close to actual driver for now.
All the work has been done so that it compiles and links with ReactOS
SDK though.
- Cache the RootFcb so that its cleanup can be handled separately
during dismounting.
- Force volume dismount at cleanup if the VCB_DISMOUNT_PENDING flag
is set.
- Actually dismount a volume if its VCB has been flagged as not good,
or if we force dismounting.
NOTE: In their *CheckForDismount() function, our 3rd-party FS drivers
as well as MS' fastfat, perform a comparison check of the current VCB's
VPB ReferenceCount with some sort of "dangling"/"residual" open count.
It seems to be related to the fact that the volume root directory as
well as auxiliary data stream(s) are still opened, and only these are
allowed to be opened at that moment. After analysis it appears that for
the ReactOS' fastfat, this number is equal to "3".
- On dismounting, cleanup and destroy the RootFcb, VolumeFcb and the
FATFileObject. Then cleanup the SpareVPB or the IoVPB members, and
finish by removing the dismounted volume from the VolumeListEntry
and cleaning up the notify synchronization object and the resources.
- During dismounting, and on shutdown, flush the volume before
resetting its dirty bit.
- On shutdown, after volume flushing, try to unmount it without forcing.
- Release the VCB resources only when we actually dismount the volume
in VfatCheckForDismount().
- Initialize first the notify list and the synchronization object,
before sending the FSRTL_VOLUME_MOUNT notification.
- If we failed at mounting a volume but its VCB's FATFileObject was
already initialized, first call CcUninitializeCacheMap() on it
before dereferencing it.
- Send FSRTL_VOLUME_LOCK, FSRTL_VOLUME_LOCK_FAILED and
FSRTL_VOLUME_UNLOCK notifications during volume locking (and failure)
and volume unlocking.
- Flush the volume before locking it, and clean its dirty bit if needed.
NOTE: In addition to checking for VCB_CLEAR_DIRTY, we also check for the
presence of the VCB_IS_DIRTY flag before cleaning up the dirty bit: this
allows us to not re-clean the bit if it has been previously cleaned.
This is needed for instance in this scenario:
- The volume is locked (it gets flushed and the dirty bit is possibly cleared);
- The volume then gets formatted with a completely different FS, that
possibly clears up the first sector (e.g. BTRFS ignores 1st sector);
- The volume is then dismounted: if we didn't check whether VCB_IS_DIRTY
was set prior to resetting it, we could attempt clearing it again! But
now that the volume's filesystem has been completely changed, we would
then try to modify the dirty bit on an erroneous position on disk!
That's why it should not be touched in this case during dismounting.
- The volume is unlocked (same comment as above), and later can be
detected as being BTRFS.
We first check if a socket is listening before
checking whether it has connections. This allows
properly returning listening address.
Furthermore, if it's listening, properly return
status so that it displays nice in netstat.
Result: https://twitter.com/HeisSpiter/status/1064245622323200000 :-)
This leaked at least one IRP for every write, making it the largest leak when
running with BTRFS as the system volume.

Up to now, it was working by chance. Indeed, due to the invalid
ASCII check performed before calling FsRtlIsAnsiCharacterLegalHpfs(), the
macro is improperly called and overruns the FsRtlLegalAnsiCharacterArray
buffer. Fortunately, up to now, right after that buffer in kernel binary
there are strings which are more or less consistent with the flags that
are expected by the macro, causing a decent behavior of
FsRtlIsAnsiCharacterLegalHpfs() even for extended ASCII characters
(whereas FsRtlIsAnsiCharacterLegalHpfs() is only designed for ASCII
characters). But this is a totally out of control and wrong behavior.
A single change in the way the kernel was built could have caused the
CDFS driver not to work as previously.
I have made the choice to allow any extended ASCII character as done
for the unicode characters. This is a good compromise to avoid drastic
regressions for users having extended ASCII characters in their CD
file names.
This imports proposed upstream commit 1b6b625641dffb49951e60398e1a9c672318ea71

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
