This also makes the dlltool tests run more PE targets, finding that

cares about that.

Revert commit 0398b8d6c8. Remove target_xfail.
This patch tidies dlltool code dealing with adding a leading
underscore to generated symbol names. There should be no functional
change here, but there could be if we ever have a bfd target with
symbol_leading_char something other than '_' or 0.
* dlltool.c (leading_underscore): Change from an int to a
char*. Update all uses. If neither --leading-underscore or
--no=leading-underscore is given, set leading_underscore to a
string with first char returned by bfd_get_target_info as the
target's symbol underscoring.
Allow for "snnnnn.o" suffix when testing against NAME_MAX, and tidy
TMP_STUB handling by overwriting a prior nnnnn.o string rather than
copying the entire name.
* dlltool.c (TMP_STUB): Add "nnnnn.o" to format.
(make_one_lib_file): Localise variables. Don't copy TMP_STUB,
overwrite suffix instead.

During the execution of the command: i686-w64-mingw32-dlltool
--input-def $def_filepath --output-delaylib $filepath --dllname qemu.exe
An error occurred:
i686-w64-mingw32-dlltool: failed to open temporary head file: ..._w64_mingw32_nativesdk_qemu_8_2_2_build_plugins_libqemu_plugin_api_a_h.s
Due to the path length exceeding the Linux system's file name length
limit (NAME_MAX=255), the temporary file name generated by the
i686-w64-mingw32-dlltool command becomes too long to open. To address
this, a new temporary file name prefix is generated using tmp_prefix =
prefix_encode ("d", getpid()), ensuring that the file name does not
exceed the system's length limit.

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.
Some places matching the first char of a string against
bfd_get_symbol_leading_char, which may be zero, didn't check for the
string being "". This patch adds the check to stop accesses past the
end of the string and potential buffer overruns.
The dlltool one was found by oss-fuzz quite a while ago.

Avoid the use of sprintf with a "%s" format string, replacing with
strcpy or stpcpy. Use sprintf return value rather than a later
strlen. Don't use strcat where we can keep track of the end of a

This adds a mingw target for aarch64, including windres and dlltool.
Note that the old value of jmp_aarch64_bytes was wrong, and this does
the same thing as MSVC does.
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 copy of cgen was with commit d1dd5fcc38ead reverted as that commit

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.

This patch performs a run-time test that a shared libbfd.so has been
compiled with the same size bfd_vma as that of apps using the library.
On a 32-bit host it is easily possible to have one libbfd.so compiled
to support 64-bit targets (or configured with --enable-64-bit-bfd)
while another only supports 32-bit targets. The two libraries will
have differently sized bfd_vma types, and if the wrong one is loaded
all sorts of weird behaviour might be seen.
