This option compresses output debug sections with zstd and sets ch_type
to ELFCOMPRESS_ZSTD.  Latest gdb and lldb support ELFCOMPRESS_ZSTD.

There will be an error if zstd is not enabled at configure time.

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.
