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.
This patch adds initial in-gas opcode relaxation for the rl78
backend. Specifically, it checks for conditional branches that
are too far and replaces them with inverted branches around longer
fixed branches.
* elf32-rl78.c (rl78_elf_howto_table): Add R_RL78_RH_RELAX.
(rl78_reloc_map): Add BFD_RELOC_RL78_RELAX.
(rl78_elf_relocate_section): Add R_RL78_RH_RELAX, R_RL78_RH_SFR,
and R_RL78_RH_SADDR.
(rl78_elf_finish_dynamic_sections): Only validate PLT section if
we didn't relax anything, as relaxing might remove a PLT reference
after we've set up the table.

(reloc_bubblesort): New.
(rl78_offset_for_reloc): New.

instructions into short ones.
