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 provides some minimal thread-safety to BFD.
The BFD client can request thread-safety by providing a lock and
unlock function. The globals used during BFD creation (e.g.,
bfd_id_counter) are then locked, and the file descriptor cache is also
locked. A function to clean up any thread-local data is now provided
for BFD clients.

bfd_close ought to always call iovec->bclose so that cache_bclose is
called. If not, bfd_last_cache will be left pointing at freed memory.
This bug was found by oss-fuzz with the trigger being an old bug in
the ia64-vms support. Given a file of the "wrong" size,
elf64_vms_close_and_cleanup attempted to extend it, leading to an
error since the file was opened read-only by nm. nm bad_file bad_file
then hit the use-after-free when opening the second file.
commit 8219cab3f8 fixed multiple bugs of this type in bfd_close and
bfd_close_all_done, but didn't go quite far enough.

A number of backends want to return bfd_reloc_dangerous messaqes from
relocation special_function, and construct the message using asprintf.
Such messages are not freed anywhere, leading to small memory leaks
inside libbfd. To limit the leaks, I'd implemented a static buffer in
the ppc backends that was freed before use in asprintf output. This
patch extends that scheme to other backends using a shared static
buffer and goes further in freeing the buffer on any bfd_close.
The patch also fixes a few other cases where asprintf output was not
freed after use.

bfd_free_cached_info is used in just one place in archive.c, which
means most times we reach bfd_close the function isn't called. On the
other hand, if bfd_free_cached_info is called we can't do much on the
bfd since it loses all its obj_alloc memory. This restricts what can
be done in a target _close_and_cleanup. In particular you can't look
at sections, which leads to duplication of code in target
close_and_cleanup and free_cached_info, eg. elfnn-aarch64.c.

bfd/doc/chew.c extracts documentation from source code comments
annotated with keywords, and generates much of bfd.h and libbfd.h from
those same comments. The docs have suffered from people (me too)
adding things like CODE_FRAGMENT to the source to put code into bfd.h
without realising that CODE_FRAGMENT also puts @example around said
code into the docs. So we have random senseless things in the docs.
This patch fixes that problem (well, the senseless things from
CODE_FRAGMENT), moves most of the code out of bfd-in.h, and improves a
few chew.c features. libbfd.h now automatically gets ATTRIBUTE_HIDDEN
prototypes, and indentation in bfd.h and libbfd.h is better.

bfd_malloc_and_get_section does size sanity checking before allocating
memory and reading contents. These size checks are not done for bss
style sections, because they typically don't occupy file space and
thus can't be compared against file size. However, if you are
expecting to look at something other than a whole lot of zeros, don't
allow fuzzers to avoid the size checking.

When reading the BFD manual, I noticed text like this:
-- Function: bool bfd_close (bfd *abfd);
Close a BFD. If the BFD was open for writing, then pending
operations are completed and the file written out and closed. If
...
*Returns*
'TRUE' is returned if all is ok, otherwise 'FALSE'.
The *Returns*, like the *Synopsis* in the earlier patch, is
un-info-like. It's also used inconsistently.
This patch removes all the uses of the RETURNS word and removes it
entirely from the chew scripts. Now this example reads:
-- Function: bool bfd_close (bfd *abfd);
Close a BFD. If the BFD was open for writing, then pending
operations are completed and the file written out and closed. If
...
'TRUE' is returned if all is ok, otherwise 'FALSE'.
In a few cases I had to slightly reword the comment. There were also
a couple of cases where there was redundant text. In these cases I
just dropped the RETURNS copy.

If file size is calculated by bfd_get_file_size, as it is by
_bfd_alloc_and_read calls in coff_object_p, then it is cached and when
pe_ILF_build_a_bfd converts an archive entry over to BFD_IN_MEMORY,
the file size is no longer valid. Found when attempting objdump -t on
a very small (27 bytes) ILF file and hitting the pr24707 fix (commit
781152ec18f5). So, clear file size when setting BFD_IN_MEMORY on bfds
that may have been read. (It's not necessary in writable bfds,
because caching is ignored by bfd_get_size when bfd_write_p.)
I also think the PR 24707 fix is no longer neeeded. All of the
testcases in that PR and in PR24712 are caught earlier by file size
checks when reading the symbols from file. So I'm reverting that fix,
which just compared the size of an array of symbol pointers against
file size. That's only valid if on-disk symbols are larger than a
host pointer, so the test is better done in format-specific code.

It seems reasonable to continue after errors in bfd_close_all_done,
particularly since bfd_close_all_done is typically called on an output

bfd_create.

Linker plugin_object_p opens the IR archive for each IR archive member.
For GCC plugin, plugin_object_p closes the archive file descriptor. But
for LLVM plugin, the archive file descriptor remains open. If there are
3000 IR archive members, there are 3000 file descriptors for them. We
can run out of file descriptors petty easily.

we can cache and reuse the IR archive file descriptor for all IR archive
members in the archive.

git commit 7b958a48e132 put the bfd filename in the bfd objalloc
memory. That means the filename is freed by _bfd_free_cached_info.
Which is called by _bfd_compute_and_write_armap to tidy up symbol
tables after they are done with.
Unfortunately, _bfd_write_archive_contents wants to seek and read from
archive elements after that point, and if the number of elements
exceeds max_open_files in cache.c then some of those elements will
have their files closed. To reopen, you need the filename.

ldmain.c:add_archive_element copies file name pointers from the bfd to
a lang_input_statement_type.
input->filename = abfd->filename;
input->local_sym_name = abfd->filename;
This results in stale pointers when twiddling the bfd filename in
places like the pe ld after_open. So don't free the bfd filename,
and make copies using bfd_alloc memory that won't result in small
memory leaks that annoy memory checkers.

This large patch removes the unnecessary bfd parameter from various
bfd section macros and functions. The bfd is hardly ever used and if
needed for the bfd_set_section_* or bfd_rename_section functions can
be found via section->owner except for the com, und, abs, and ind
std_section special sections. Those sections shouldn't be modified
anyway.
The patch also removes various bfd_get_section_<field> macros,
replacing their use with bfd_section_<field>, and adds
bfd_set_section_lma. I've also fixed a minor bug in gas where
compressed section renaming was done directly rather than calling
bfd_rename_section. This would have broken bfd_get_section_by_name
and similar functions, but that hardly mattered at such a late stage
in gas processing.

This introduces a new bfd_set_filename function, which is then used in
various spots in gdb. This allows for the removal of some casts.
