binutils-gdb/gprofng/libcollector/iotrace.c
Alan Modra fd67aa1129 Update year range in copyright notice of binutils files 
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.
