Fixes a regression from 99fa38809f, which
replaced the kcom.h/stdunk.h versions (which zero memory) with local
implementations (which don't).
Standard C++ does not guarantee that memory is zeroed but several classes
rely on this, in particular for their m_Ref and m_bInitialized members.
Ideally the constructors should be fixed to initialize all required members,
but that task is error-prone so for now we simply restore the previous
behavior.
- 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

* [ADVAPI32] Simplify RtlCreateUnicodeStringFromAsciiz() return value check
RtlCreateUnicodeStringFromAsciiz() returns a BOOLEAN, not a BOOL.
No functional change.
Addendum to
CORE-14271
* [USER32] Simplify RtlCreateUnicodeStringFromAsciiz() return value check
RtlCreateUnicodeStringFromAsciiz() returns a BOOLEAN, not a UINT.
Also, add a FIXME.
No functional change.

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.
