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.
Tidies:
- Move stuff from bfd-in.h and libbfd.c to compress.c
- Delete COMPRESS_DEBUG from enum compressed_debug_section_type
- Move compress_debug field out of link_info to ld_config.
Fixes:
- Correct test in bfd_convert_section_setup to use obfd flags,
not ibfd.
- Apply bfd_applicable_file_flags to compression bfd flags added
by gas and ld to the output bfd.

PR29397 PR29563: Add new configure option --with-zstd which defaults to
auto. If pkgconfig/libzstd.pc is found, define HAVE_ZSTD and support
zstd compressed debug sections for most tools.

* objcopy: support ELFCOMPRESS_ZSTD input for

* gdb: support ELFCOMPRESS_ZSTD input. The bfd change references zstd
symbols, so gdb has to link against -lzstd in this patch.
If zstd is not supported, ELFCOMPRESS_ZSTD input triggers an error. We
can avoid HAVE_ZSTD if binutils-gdb imports zstd/ like zlib/, but this
is too heavyweight, so don't do it for now.

These two macros print either a 16 digit hex number or an 8 digit
hex number. Unfortunately they depend on both target and host, which
means that the output for 32-bit targets may be either 8 or 16 hex
digits.
Replace them in most cases with code that prints a bfd_vma using
PRIx64. In some cases, deliberately lose the leading zeros.
This change some output, notably in base/offset fields of m68k
disassembly which I think looks better that way, and in error
messages. I've kept leading zeros in symbol dumps (objdump -t)
and in PE header dumps.

There is a problem with my commit 0e3c1eebb2, which replaced
bfd_uint64_t with uint64_t: Some hosts typedef int64_t to long long
even when long is the same size as long long. That confuses the code
choosing one of "l", "ll", or "I64" for BFD_VMA_FMT, and results in
warnings.
Write a direct configure test for the printf int64_t style instead.
This removes the last use of BFD_HOST_64BIT_LONG, so delete that.
Note that the changes to configure.com are pure guesswork.

bfd_hostptr_t is defined as a type large enough to hold either a long
or a pointer. It mostly appears in the coff backend code in casts.
include/coff/internal.h struct internal_syment and union
internal_auxent have the only uses in data structures, where
comparison with include/coff/external.h and other code reveals that
the type only needs to be large enough for a 32-bit integer or a
pointer. That should mean replacing with uintptr_t is OK.
Requiring C99 means that uses of bfd_uint64_t can be replaced with
uint64_t, and similarly for bfd_int64_t, BFD_HOST_U_64_BIT, and
BFD_HOST_64_BIT. This patch does that, removes #ifdef BFD_HOST_*
and tidies a few places that print 64-bit values.
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

Sometimes the investigation of a fuzzing bug report leads into areas

to rip it out.

This defines a couple of macros used to avoid ubsan complaints about
calculations involving NULL pointers. PTR_ADD should be used in the
case where it is known that the offset is always zero with a NULL
pointer, and you'd like to know if a non-zero offset is ever used.
NPTR_ADD should be rarely used, but is defined for cases where a
non-zero offset is expected and should be ignored if the pointer is
NULL.
