Add these NTSTATUS codes in the CMLIB library. STATUS_INVALID_PARAMETER will be used mostly for HvInitialize function, STATUS_REGISTRY_IO_FAILED for whatever routines that deal with reading or writing into a hive file.
This header is included by ntoskrnl which effectively disabled all PAGED_CODE checks since 2015. Thanks Alex.
Instead define _BLDR_ when building cmlib, which will avoid trying to import KeGetCurrentIrql()
In principle there should be different get-cell routines, depending
on the type of the hive (given by the OperationType parameter of
HvInitialize): for flat hives, memory-mapped hives, etc.
For now in ReactOS we only support a restricted subset of these,
therefore we are still happy with a single get-cell callback...
This may change in the future.
