This fixes a regression introduced in 5ab1cfc which
was causing Unix (BtrFS, ExtX, and so on) volumes not
to be assigned a drive letter assigned anymore. And
thus, they were no longer mounted and presented to the
users.

- Import KdpCopyMemoryChunks() from kd64/kdapi.c, and re-implement
KdbpSafeReadMemory() and KdbpSafeWriteMemory() around it.
Note that these functions read virtual memory and are equivalent of
the kd64 KdpReadVirtualMemory() and KdpWriteVirtualMemory()
respectively.
- Get rid of the KdpEnableSafeMem() call in KdInitSystem().
- Adjust kd gdbstub.c wrapper in accordance.
We allow specifying manually the TSS selector number or its descriptor address,
and dump more information from the associated KTSS structure.
Also add the KdbpRetrieveTss() helper to retrieve the PKTSS from its
corresponding selector number. It will also be useful for future improvements.
As documented in https://docs.microsoft.com/fr-fr/windows-hardware/drivers/ddi/wdm/nf-wdm-exallocatepoolwithtag
pool tag "characters" must be a value in the range 0x20 (space) to 0x7E (tilde),
which happen indeed to be the range of printable (non-extended) ASCII characters.
(The display problem was originally caught while attempting to display
the pool tag 0x3a306847 corresponding to 'Gh0:', a win32ss GDIOBJ pool tag
encoded with macro GDIOBJ_POOL_TAG().)
The major change with this rewrite is the support for the mount
manager. Fstub will now assume that most of the devices are PnP
and that they are already registered to the mount manager.
It will thus ask the mount manager to assign the drive letter.
Fstub will keep assigning drive letters non mission critical devices
such as CDs, floppies and other removable devices.
See MountMgr:QueryPoints API test that will now return mount points :-).
* [NTOS:INBV] Move typedefs to the only single file where they are used.
* [NTOS:INBV] Refactor code & resources
Remove garbage
* [NTOS:INBV] Reduce fade time and remove wait for animation.
They don't need to have a zeroed-out palette now that we can
automatically reset it from within the code.

This allows setting the memory protection of the kernel's resource
section as will. MmMakeKernelResourceSectionWritable() is re-implemented
around this helper.
This also makes it necessary to fix a bug in the previous code:
ZwEnumerateKey will not account for space for a null terminator, so to
ensure we have space, we must allocate the additional WCHAR, but not
include it in the buffer size passed to the function.
For MSVC, marking the section as discardable will do this automatically.
For GCC, we use a linker script that places it after the .reloc section
(which should be the last "real" section, check ld --verbose output for the
default linker script).
This fixes what seems to be a regression from r55835 (!).
