without backward compat (it shortlived in a development branch).

Kamil Rytarowski b6195b59a6 Skip two more ioctl interceptors for NetBSD
Don't intercept:
 - HFSC_IF_ATTACH
 - HFSC_MOD_CLASS

These operations conflict on NetBSD 32-bit with:
 - PRIQ_IF_ATTACH
 - PRIQ_MOD_CLASS

Kamil Rytarowski 5ffda0cc1f Teach sanitizer about NetBSD specific ioctl(2) calls
Summary:
Introduce handling of 1200 NetBSD specific ioctl(2) calls.
Over 100 operations are disabled as unavailable or conflicting
with the existing ones (the same operation number).

Add a script that generates the rules to detect ioctls on NetBSD.
The generate_netbsd_ioctls.awk script has been written
in NetBSD awk(1) (patched nawk) and is compatible with gawk.

Generate lib/sanitizer_common/sanitizer_interceptors_ioctl_netbsd.inc
with the awk(1) script.

Update sanitizer_platform_limits_netbsd accordingly to add the needed
definitions.

Kamil Rytarowski 39628a7ab0 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.

This is the first (1/2) part of a change that moves llvm-symbolizer to llvm/tools/, which will allow to build it
with both cmake and configure+make.
