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.

Because _bfd_read_unsigned_leb128 is hidden visibility, so it can't
be referenced out of shared object.
The new function loongarch_get_uleb128_length just used to call
_bfd_read_unsigned_leb128.
bfd/ChangeLog:
* elfxx-loongarch.c (loongarch_get_uleb128_length): New function.
* elfxx-loongarch.h (loongarch_get_uleb128_length): New function.
gas/ChangeLog:
* config/tc-loongarch.c (md_apply_fix): Use
loongarch_get_uleb128_length.

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.

Replace the magic numbers in gas(tc-loongarch.c) and
bfd(elfnn-loongarch.c) with the functions defined in
the howto table(elfxx-loongarch.c).

* config/tc-loongarch.c: use functions.

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.
