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.
The newer update-copyright.py fixes file encoding too, removing cr/lf
on binutils/bfdtest2.c and ld/testsuite/ld-cygwin/exe-export.exp, and
embedded cr in binutils/testsuite/binutils-all/ar.exp string match.
The result of running etc/update-copyright.py --this-year, fixing all
the files whose mode is changed by the script, plus a build with
--enable-maintainer-mode --enable-cgen-maint=yes, then checking
out */po/*.pot which we don't update frequently.
The copy of cgen was with commit d1dd5fcc38ead reverted as that commit
breaks building of bfp opcodes files.
Newer versions of bison emit a prototype for yyerror
void yyerror (const char *);
This clashes with some of our old code that declares yyerror to return
an int. Fix that in most cases by modernizing yyerror. bfin-parse.y
uses the return value all over the place, so for there disable
generation of the prototype as specified by posix.
binutils/
* arparse.y (yyerror): Return void.
* dlltool.c (yyerror): Likewise.
* dlltool.h (yyerror): Likewise.
* sysinfo.y (yyerror): Likewise.
* windmc.h (yyerror): Likewise.
* mclex.c (mc_error): Extract from ..
(yyerror): ..here, both now returning void.
gas/
* config/bfin-parse.y (yyerror): Define.
(yyerror): Make static.
* itbl-parse.y (yyerror): Return void.
ld/
* deffilep.y (def_error): Return void.
When the tokens MCLINE, MCENDLINE, and MCCOMMENT were created, the
line number was not increased, which led to an incorrect value in
the error output.

* mclex.c (skip_until_eol): if eol was found, increment line number
