QueryDeviceInformation returns more reliable volume length and works
with unformatted volumes. It will return volume length only on ROS and Vista+ however,
so also keep the GetFreeDiskSpaceExW as a fallback for XP/2003.
During investigation into some of the USB stack issues we've been running into I've found that when a USB storage device is already plugged in during boot and removed before it finishes initialization we run into this assert.
The logic in this function removes the pools made for the following entries in DeviceExtension indiscriminately this makes debugging a bit more difficult. Instead of depending on this behavior of ALWAYS being filled with valid data, let's free the following pools ONLY if they're initialized. This change prevents us from bugchecking when USB flash drives are removed early during boot. This makes the debugging experience a little more sane.
- `ArcOpen()`: flatten the registered-device search for-loop.
Limit it to just the device search, and exit early.
The rest of the initialization is now done outside the loop.
- The `DeviceName` string pointer may have been allocated from
the heap, for path normalization (see `NormalizeArcDeviceName()`).
This pointer is then only used in the device search loop and not
nused anymore afterwards. The old code didn't free this pointer
and memory could leak. This is now fixed easily, thanks to the
loop flattening.
- Rename `DEVICE` member `Prefix` to `DeviceName`; SAL-annotate
`FsRegisterDevice()`.
- Replace a lot of `MAX_FDS` by `_countof(FileData)`;
- The duplicated FileId validation logic is wrapped with
the `IS_VALID_FILEID()` macro.
- When returning an invalid FileId value on purpose, use
`INVALID_FILE_ID` instead of `MAX_FDS` (that could vary
if the file handle table gets extended).
And replace the `(ULONG)-1` also used for that purpose
by `INVALID_FILE_ID`.
- Add missing DeviceId invalidation:
* when failing to open a file handle in `ArcOpen()`;
* when registering a new device in `FsRegisterDevice()`.
There, having DeviceId always set to zero would tell
the code that the corresponding device's file ID is
the first one in the table, which is a BUG. (Many devices
would have the same file ID...)
- In addition: massage a bit some indicial for-loops.
This allows to make the code better extendable: adding a new FS
mount routine into the table, instead of duplicating also a whole
`if (!FileFuncTable) ...` check.
Later, this table will be made dynamic, so that new filesystems could be
dynamically registered at runtime, and a filesystem could be forced to
be mounted by the user (using a specific syntax).

Thanks to the following testers!
- Dmitry Borisov (@disean) for testing on NEC PC-98 emulator;
- Justin Miller (@DarkFire01) for testing on UEFI platform;
- Stanislav Motylkov (@binarymaster) for testing on Xbox emulator
(xemu), both livecd and bootcd.

"SectorsPerTrack" is for the legacy Cylinders/Heads/Sectors(PerTrack)
scheme.
- On BIOS-based PCs, INT 13h can return (for LBA-only drives) an invalid
geometry, like: C/H/S = (-1)/(-1)/(-1). This is also what happens in
our hwide.c driver (see IdentifyDevice() for ATAPI devices):
db419efbf2/boot/freeldr/freeldr/arch/drivers/hwide.c (L918-L928)
as well as on VirtualBox for CD-ROMs:
https://www.virtualbox.org/browser/vbox/trunk/src/VBox/Devices/PC/BIOS/disk.c#L155
- Therefore, we cannot reliably calculate a valid total number of sectors
by multiplying the Cylinders*Heads*SectorsPerTrack values. In addition,
such a multiplication could overflow a 32-bit ULONG.
Thus, a separate ULONGLONG Sectors member is required to hold such a
value, that is retrieved differently. For example for ATAPI devices,
our hwide.c driver does return a valid TotalSectors value, even though
CHS values are invalid. Other platforms, like UEFI, just work using
logical block addressing (LBA) values (see EFI_BLOCK_IO_MEDIA).
- uefidisk.c : Per the spec, EFI_BLOCK_IO_MEDIA::LastBlock contains
"The last LBA on the device. [...] For ATA devices, this is reported
in IDENTIFY DEVICE data words 60-61 (i.e., Total number of user
addressable logical sectors) _minus one_.
For SCSI devices, this is reported in the READ CAPACITY parameter
data 'Returned Logical Block Address field' _minus one_."
In other words, LastBlock is a zero-based LBA index quantity. The
corresponding total number of valid "sectors"/blocks of the device
is therefore, (LastBlock + 1).
- Cleanup some old disabled code.

* [WINESYNC] msi: Install and patch global assemblies in InstallFinalize.
Installing global assemblies requires assembly caches to be initialized and
this is no longer the case after the PE conversion (builtin fusion no longer
loads if the dll is not present on disk).
The next patch changes msi to perform late initialization of the assembly
caches so that native fusion can be loaded once it's installed by .NET
installers. However, there's no guarantee that all necessary files and
registry keys are installed before the InstallFiles and PatchFiles actions
are executed. Therefore this patch moves the parts of these actions handling
global assemblies to InstallFinalize.

Commit b1cc87cb656 ("msi: The line control has a height of exactly 2

(msi_)dialog_add_control() inside dialog_line_control() modulo the
height override.
Except the fixed height, line controls have nothing special compared to
other controls. Thus, there is little merit in open-coding it.
Also, dialog_line_control() has bit-rotted over time; it already missed
a few changes that were done to any other controls.
Fix this by just using dialog_add_control(). Also, add a special case
logic just for line controls.

We had a mixup between languages regarding WS_CHILD, CBS_SORT for some comboboxes.
Harmonize that by:
- Strip explicit WS_CHILD from all comboboxes (because it is implicitly available)
- Strip CBS_SORT from IDC_EFFAPPEARANCE_ANIMATIONTYPE and IDC_EFFAPPEARANCE_SMOOTHINGTYPE because Windows does not sort them.
This fixes the wrong order in those controls

CORE-6905
This commit tries to improve the quality of the screenshots that we do get posted in JIRA,
where we couldn't even see up to now which build and arch was run.
This is in the wider context of CORE6762
(I intentionally left out the minus in the CORE-ID to prevent auto-linkage to that ticket)
When the Int 13h AH=42h "Extended read" function fails, the disk address
packet's LBA block count is reset to the number of blocks that have been
successfully transferred. This is more or less fine, unless one wants to
ensure the exact number of sectors gets read.
If the function fails so that zero sectors were read, the retry loop is
restarted, but with the packet's LBA block count member reset, as per
the documentation. (In this example, it is reset to zero.) Then, at the
next retry attempt, zero sectors are requested to be read, and this time
of course, the call succeeds... Wrongly, of course, this is not what's
expected.
Therefore, for each retry, the LBA block count member should be set
again to the correct number of sectors to read. There are maximum 3
retries, so the retry loop will stop anyway, but the LBA read will now
correctly fail and return FALSE, as expected.
This problem doesn't exist in the retry loop for the Int 13h, AH=02h
"Read Disk Sectors" CHS function, because here, the call is made only
using registers, and we use a pair of RegsIn/RegsOut. RegsOut receives
the modified register values, but the input RegsIn stays unchanged.
For reference, see the cdfs/cd.h RAW_ISO_VD structure.
Each of the old "VolumeSetSize", "VolumeSequenceNumber" and "LogicalBlockSize"
ULONG fields actually correspond to pairs of USHORT fields:
"VolumeSetSizeL" and "VolumeSetSizeM", etc., where the "L" one contains
the value in little-endian format, while the "M" one contains the same
value in big-endian format.
Additionally, use UCHARs for the character arrays.
Create the section with PAGE_READWRITE, not PAGE_EXECUTE_READWRITE and map in user mode with PAGE_READONLY, not PAGE_EXECUTE_READ.

"Size", "Installed on", ...) and the possibility to show/hide columns.
