Add NetBSD syscall hooks skeleton in sanitizers
Summary: Implement the skeleton of NetBSD syscall hooks for use with sanitizers. Add a script that generates the rules to handle syscalls on NetBSD: generate_netbsd_syscalls.awk. It has been written in NetBSD awk(1) (patched nawk) and is compatible with gawk. Generate lib/sanitizer_common/sanitizer_platform_limits_netbsd.h that is a public header for applications, and included as: <sanitizer_common/sanitizer_platform_limits_netbsd.h>. Generate sanitizer_syscalls_netbsd.inc that defines all the syscall rules for NetBSD. This file is modeled after the Linux specific file: sanitizer_common_syscalls.inc. Start recognizing NetBSD syscalls with existing sanitizers: ASan, ESan, HWASan, TSan, MSan.
