Kamil Rytarowski 01f91c3526 [compiler-rt] Sync NetBSD syscall hooks with 9.99.17
Document the minimal version supported as 9.0 and add compat code for
renamed syscalls after 9.0.

Chandler Carruth 2946cd7010 Update the file headers across all of the LLVM projects in the monorepo
to reflect the new license.

We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.

Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Kamil Rytarowski 4f343547ba Regenerate syscall hooks for NetBSD 8.99.25
Register new syscall getsockopt2.
Drop removed syscalls pmc_get_info and pmc_control.

While there address compiler warnings about potentially
unused variables.

Kamil Rytarowski a51ccfd49f Remove more references to ptrace_pt_{g,s}et_sigmask
These operations are now obsolete on NetBSD and will be removed.

No functional change for other OSes.

PT_SET_SIGMASK and PT_GET_SIGMASK will be removed from NetBSD
without backward compat (it shortlived in a development branch).

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.
