Work around yet another bug in SDV
It appears that SDV objects to the symbol 'Constrain' being defined,
presumably because it uses it internally in some way. This patch
therefore re-codes the static inline Constrain function in ring.c as a
macro to avoid the clash.

Dynamically build key-code to usage map
This patch creates a header defining the linux keycodes used by the
vkbd protocol and macros to map those (by name) to HID usage codes.
A new function then makes use of these of the new definitions and macros
to create a direct mapping from key-code to usage dynamically during
ring initialization.
The patch also adds missing locking inside the DPC and a shutdown race
which could occasionally free the ring structure from underneath the DPC.

Fix HID code for KEY_ENTER
The VkbdKeyCodeToUsage array has the value for KEY_ESCAPE (0x29)
incorrectly placed in this entry. This patch replaces that with 0x28, which
is the correct code for the ENTER key.

Make sure Mdl->StartVa is set by __AllocatePages()
wdm.h carries this comment:
// Notice that while in the context of the subject thread, the base virtual
// address of a buffer mapped by an MDL may be referenced using the
// following:
//
// Mdl->StartVa | Mdl->ByteOffset
//
Hence it is important that a mapped MDL has a valid StartVa field as well
as a valid MappedSystemVa field. Unfortunately, for reasons best known to
Microsoft, MmMapLockedPagesSpecifyCache() does not ensure this is the
case, so it needs to be fixed up by __AllocatePages() itself.

Update kbdif.h and use feature-raw-pointer
Updates the xen public header to include the definition of
[feature|request]-raw-pointer.
Renames VkbdStandalone to RawPointer and uses the newly defined feature
