oss-fuzz generated a total length field of 32, when the header was 40
bytes. Subtracting gave -8ul for the remaining length..
I think we should be sanity checking the total length given in the
header against the remaining buffer length and the size of the header
each time get_version_header is called.
Possibly vallen should be sanity checked inside get_version_header
too, but I'll leave that to someone else.

Move len vs. buffer length sanity check..

against off.
Commit c6c8d0b821 went completely the wrong way. "key" needs to be
NULL as that reads a different type of data.

* resbin.c (get_version_header): Don't pass a NULL key on to

(bin_to_res_version): Restore NULL key cases.
bin_to_res_menuexitems can be called with random data offsets (and thus
remaining lengths), confusing code that expects 4-byte aligned data.
Prevent an item length adjustment for alignment exceeding the
remaining length and then overflowing.
windres_get_32 and similar have a length parameter that in most cases
is just the required length, so it is redundant. The few cases where
a variable length is passed are all in resrc.c. So, get rid of the
length parameter and introduce wrappers in resrc.c to check the
length.
windres code has the habit of exiting on any error. That's not so
bad, but it does make oss-fuzz ineffective when testing windres. Fix
many places that print errors and exit to instead print the error and
pass status up the call chain. In the process of doing this, I
noticed write_res_file was calling bfd_close without checking return
status. Fixing that resulted in lots of testsuite failures. The
problem was a lack of bfd_set_format in windres_open_as_binary, which
leaves the output file as bfd_unknown format. As it happens this
doesn't make any difference in writing the output binary file, except
for the bfd_close return status.
oss-fuzz testcase manages to hit a buffer overflow. Sanity check
by passing the buffer length to bin_to_res_toolbar and ensuring reads
don't go off the end of the buffer.
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.
