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.
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).
I don't see much point in cluttering the source with the PROGRESS

After bfd_close nothing should access bfd memory. Now that bfd_close

The copy of cgen was with commit d1dd5fcc38ead reverted as that commit
breaks building of bfp opcodes files.
After commit 985e026451 copy_archive function began to pass invalid
values to the utimensat(2) function when it tries to preserve
timestamps in ar archives. This happens because the bfd_stat_arch_elt
implementation for ar archives fills only the st_mtim.tv_sec part of
the st_mtim timespec structure, but leaves the st_mtim.tv_nsec part
and the whole st_atim timespec untouched leaving them uninitialized

This patch makes use of the temp file descriptor in smart_rename

Renaming over existing files needs additional care to restore
permissions and ownership, which may not always succeed.
Additionally, other properties of the file such as extended attributes
may be lost, making the operation flaky.
For predictable results, resort to rename() only if the file does not
exist, otherwise copy the file contents into the existing file. This
ensures that no additional tricks are needed to retain file
properties.
This also allows dropping of the redundant set_times on the tmpfile in
objcopy/strip since now we no longer rename over existing files.

smart_rename is capable of handling symlinks by copying and it also
tries to preserve ownership and permissions of files when they're
overwritten during the rename. This is useful in objcopy where the
file properties need to be preserved.
However because smart_rename does this using file names, it leaves a
race window between renames and permission fixes. This change removes
this race window by using file descriptors from the original BFDs that
were used to manipulate these files wherever possible.
The file that is to be renamed is also passed as a file descriptor so
that we use fchown/fchmod on the file descriptor, thus making sure
that we only modify the file we have opened to write. Further, in
case the file is to be overwritten (as is the case in ar or objcopy),
the permissions that need to be restored are taken from the file
descriptor that was opened for input so that integrity of the file
status is maintained all the way through to the rename.

The purpose of creating a temporary file securely using mkstemp is

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.
