Historically, we have used several APIs (perfctr, libcpc, perf_event_open) for profiling.
For each hardware we have several tables of hardware counters.
Some information is duplicated in these tables.
Some of the information is no longer used.
I did not touch the existing hwc tables.
I added a new hwc table for an AMD Zen3 machine.

interface with libcpc was used on Solaris.
gprofng doesn't support profiling on Solaris.
I removed this old code and other unused macros and variables.

Our hardware counter profiling is based on perf_event_open().
Our HWC tables are absent for new machines.
I have added HWC tables for the following events: PERF_TYPE_HARDWARE,
PERF_TYPE_SOFTWARE, PERF_TYPE_HW_CACHE. Other events require additional fixes.
Did a little cleaning: marked the symbols as static, used Stringbuilder,
created a function to read /proc/cpuinfo.

Adds two new external authors to etc/update-copyright.py to cover
bfd/ax_tls.m4, and adds gprofng to dirs handled automatically, then
updates copyright messages as follows:
1) Update cgen/utils.scm emitted copyrights.
2) Run "etc/update-copyright.py --this-year" with an extra external
author I haven't committed, 'Kalray SA.', to cover gas testsuite
files (which should have their copyright message removed).
3) Build with --enable-maintainer-mode --enable-cgen-maint=yes.
4) Check out */po/*.pot which we don't update frequently.

This adds 'Innovative Computing Labs' as an external author to
update-copyright.py, to cover the copyright notice in
gprofng/common/opteron_pcbe.c, and uses that plus another external
author 'Oracle and' to update gprofng copyright dates. I'm not going
to commit 'Oracle and' as an accepted author, but that covers the
string "Copyright (c) 2006, 2012, Oracle and/or its affiliates. All
rights reserved." found in gprofng/testsuite/gprofng.display/jsynprog
files.
