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.

This patch fixes all the warnings I found in bfd, binutils and ld,
plus some bitrotted COFF_GO32 code that tried to allocate -168ul
bytes. When the malloc fail was reported these testsuite fails
resulted:
i386-go32 +FAIL: go32 stub
i386-go32 +ERROR: tcl error sourcing /home/alan/src/binutils-gdb/ld/testsuite/ld-i386/i386.exp.
i386-go32 +ERROR: couldn't open "tmpdir/go32stub": no such file or directory
i386-go32 +FAIL: ld-scripts/sane1
i386-go32 +FAIL: ld-scripts/assign-loc
i386-go32 +FAIL: ld-scripts/pr18963
This does result in some warnings in gdb which are fixed in a followup
patch.

These were renamed from bfd_read and bfd_write back in 2001 when they
lost an unnecessary parameter. Rename them back, and get rid of a few
casts that are only needed without prototyped functions (K&R C).

Copying one too many bytes can corrupt memory, detected/reported by
glibc on a 32-bit distro.

Microsoft's DIA library, and thus also MSVC and WinDbg, expects section
contributions to be ordered by section number and offset, otherwise it's
unable to resolve line numbers.

This extends PDB support to the aarch64 PE targets.
The changes to the test files are just to make it so they can be assembled as
either x86, x86_64, or aarch64, mainly by changing the comment style.
The only actual code change here is in adding the architecture constants
to pdb.c.

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.

A few fixes to minor issues I've discovered in my PDB patches.
* If sizes or offsets are greater than 0x8000, they get encoded as
extended values in the same way as for enum values - e.g. a LF_ULONG
.short followed by a .long.
* I've managed to coax MSVC to produce another type, LF_VFTABLE, which
is seen when dealing with COM. I don't think LLVM emits this. Note that
we can't just implement everything in Microsoft's header files, as most
of it is obsolete.
* Fixes a stupid bug in the test program, where I was adding an index to
a size. The index was hard-coded to 0, so this didn't cause any actual
issues.
