golang.org/x/sys

Add a test that checks the Linux/riscv64 riscv_hwprobe constants, syscall
number, and pair layout copied into x/sys/cpu stay in sync with the
generated x/sys/unix sources.

The cpu package cannot depend on unix in production, but test files can
import it. Compare the copied definitions directly with unix rather than
parsing source files.

Kernel release strings such as "3.4.35_hi3535" on some Synology devices
failed to parse because only dash and plus suffixes were stripped.
Parse the leading digits of each component instead, mirroring the Go
runtime fix.

This copies the implementation from the Go runtime's parseRelease as
updated in CL 781800.

Fixes golang/go#80094

This adds everything needed to use Linux's GPIO V2 UAPI, including the
ioctls, structs and constants.
As on some architectures char is signed by default and the UAPI doesn't
make it unsigned explicitly a mkpost fixup is used to make the types
more usable (by things like unix.ByteSliceToString).

GetNamedSecurityInfoW may return a nil security descriptor when the
object exists but has no security descriptor. This change allows
GetNamedSecurityInfo to return a nil *SECURITY_DESCRIPTOR in that case,
instead of crashing when trying to copy the nil security descriptor.
