- Initialize the rest of IRP data which is not initialized by IoBuildSynchronousFsdRequest.
- Setup an IO_STACK_LOCATION structure for the IRP before calling the driver's read/write routine.
- Do this for both KsReadFile and KsWriteFile functions in our Kernel Streaming driver (ks.sys).
This fixes several problems when calling these functions from outside, so now they are working correctly, as expected.
Discovered during my audio investigations.
CORE-19232
Properly set output buffer length in IO Stack Location of the current IRP, since it is passed to KsProbeStreamIrp when calling KsStreamIo, so it fails if the length isn't set properly.
Don't set an input buffer length and the buffer itself, since it isn't passed anywhere, so setting it makes no sense. Moreover, MSDN says that for IOCTL_KS_READ/WRITE_STREAM, only output buffer (and its length) is needed to be set, but not an input one. So it indeed is more correct.
It fixes buffer overflow in KsProbeStreamIrp when attempting to perform the streaming via KsStreamIo. I discovered this bug during my audio refactoring from PR #4660.

transport calls to LibTCPConnect that suffer certain early failures
like parameter errors or early route lookup failures return without
initializing the pcb.
In order to avoid later BSOD's this change clears the
ConnectionRequest bucket in those cases.
- Fix IRP handling, add missing IRP handlers
- Specify the device name for DO
- The legacy IRQ descriptor is edge-triggered
- Improve pool tagging
- Place the PNP code in a pageable section

The function should return the kernel time for the idle thread in the
first argument, and kernel time + user time for the current thread in
the second argument.
Also retrieve the processor number from the cached PRCB instead of
calling KeGetCurrentProcessorNumber() which retrieves the PRCB again
since the processor could switch in-between those calls.
NdisGetCurrentProcessorCounts() function follows the same prototype
which is the correct one.
NOTE: There are no new features in this PR, we stay with upstream version 0.69.

- Add ifdefs to distinguish ReactOS code/fixes from the upstream code;
- If upstream code was overriden, reintroduce it in #else section;
- Re-align .rc version info with upstream (0.69).
- Flush Map registers once the DMA completes
- Free Map registers once the DMA completes
- Add support for SGL allocated from NonPagedPool
Test:
Force Allocations of SGL from Non Paged Pool and ensure OS boots and functions properly

- deduplication of manufacturer strings
- at some places harmonizes the different length of separator lines within the same file, centers the words (as requested by hbelusca during review), harmonizes those lines to 74characters length each
- moving some strings that are not to be localized into the non-localization string section
- other minor formatting preferences coauthored by StasM

v1.8.1 (2022-08-23):
- Fixed use-after-free when flushing
- Fixed crash when opening volume when AppLocker installed
- Compression now disabled for no-COW files, as on Linux
- Flushing now scales better on very fast drives
- Fixed small files getting padded to 4,096 bytes by lazy writer
- Added NoDataCOW registry option
'.' and '..' entries do not exist on FATX subdirectories. We have to fake them when
enumerating the directory, and ignore them when creating a FCB from a directory entry.
