The newer update-copyright.py fixes file encoding too, removing cr/lf

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.
In out_dir_and_file_list, if file 0 is copied from file 1, only the filename
is copied, and the dir and md5 fields are left to their default values.
Fix this by adding the copy of the dir and md5 fields.

Gas uses the directory part, if present, of the .file 0 directive to set
entry 0 of the directory table in DWARF 5, which represents the "current
directory".
Now Gas also uses the file part of the same directive to set entry 0 of the
file table, which represents the "current compilation file". But the latter
need not be located in the former so GCC will use a full path in the file
part when it is passed a full path:
gcc -c /full/path/test.c -save-temps
yields:
.file 0 "/current/directory" "/full/path/test.c"
in the assembly file and:
The Directory Table (offset 0x22, lines 2, columns 1):
Entry Name
0 (indirect line string, offset: 0x25): /current/directory
1 (indirect line string, offset: 0x38): /full/path
The File Name Table (offset 0x30, lines 2, columns 2):
Entry Dir Name
0 0 (indirect line string, offset: 0x43): /full/path/test.c
in the object file. Note the full path and the questionable Dir value in
the 0 entry of the file table.

gas/write.c provides a fallback TC_VALIDATE_FIX_SUB define that can be
a problem for some targets, the problem being that a non-zero
definition of TC_VALIDATE_FIX_SUB says that some uses of fx_subsy are
OK, in effect that the target will handle fx_subsy in md_apply_fix
and/or tc_gen_reloc. A lot of targets don't have the necessary
md_apply_fix and tc_gen_reloc support. So a safer default is to
disallow fx_subsy by default.
I've had a good look over target usage of fx_subsy, and think I've
caught all the cases where targets need TC_VALIDATE_FIX_SUB. Possible
failures would be limited to alpha, microblaze, ppc and s390 (the
targets that define UNDEFINED_DIFFERENCE_OK), or targets that generate
fixups with BFD_RELOC_GPREL32/16 and use a syntax explicitly showing
a difference expression.
