Update to latest gnulib with new copyright year.
Run "make update-copyright" and then...
* gnulib: Update included in this commit as copyright years
are the only change from the previous gnulib commit.
* tests/init.sh: Sync with gnulib to pick up copyright year.
* bootstrap: Likewise.
* tests/sample-test: Adjust to use the single most recent year.
build: fix od build on clang < 172024-02-07T11:13:38ZPádraig BradyP@draigBrady.com2024-02-07T10:55:00Zurn:sha1:f85472082c5920951a2886c114612c5002899fb8
* configure.ac: Ensure the compiler can promote 16 bit floating point
types to float, before enabling that code in od. This was an issue
with clang 16 at least.
* src/od.c: Adjust for the new defines.
* tests/od/od-float.sh: Likewise. Also port to the dash shell,
whose inbuilt printf doesn't support hex escapes.
od: support half precision floating point2024-02-05T13:30:45ZPádraig BradyP@draigBrady.com2024-02-01T17:59:51Zurn:sha1:76604db7d2da0ceb4de4542ebf315b3d6415f972
Rely on compiler support for _Float16 and __bf16
to support -fH and -fB formats respectively.
I.e. IEEE 16 bit, and brain 16 bit floats respectively.
Modern GCC and LLVM compilers support both types.

This was tested on:
gcc 13, clang 17 x86 (Both types supported)
gcc 7 aarch64 (Only -fH supported)
gcc 13 ppc(be) (Neither supported. Both will be with GCC 14)
* src/od.c: Support -tf2 or -tfH to print IEEE 16 bit floating point,
or -tfB to print Brain 16 bit floating point.
* configure.ac: Check for _Float16 and __bf16 types.
* doc/coreutils.texi (od invocation): Mention the new -f types.
* tests/od/od-float.sh: Add test cases.
* NEWS: Mention the new feature.

until we fully sync with gnulib at a later stage.
* tests/sample-test: Adjust to use the single most recent year.
