Run "make update-copyright" and then...
* gnulib: Update to latest with copyright year adjusted.
* tests/init.sh: Sync with gnulib to pick up copyright year.
* bootstrap: Likewise.
* tests/sample-test: Adjust to use the single most recent year.

When configured with either 'symlinks' or 'shebangs' as value for
the --enable-single-binary option, tests based on `ulimit -v` are
skipped. The reason is that the multicall 'coreutils' binary requires
much more memory due to shared libraries being loaded, and the size of
the 'date' binary (~290KiB) compared to the multicall binary (~5MiB),
of course. Finally, in the case of 'shebangs', the starting shell
requires more memory, too
Instead of using hard-coded values for the memory limit, use an
adaptive approach: first determine the amount of memory for a similar,
yet more trivial invocation of the command, and then do the real test
run using that limit (plus some buffer in some cases).
* init.cfg (require_ulimit_v_): Remove function.
(get_min_ulimit_v_): Add function to determine the minimum memory limit
required for a given command in an adaptive way.
* cfg.mk (sc_prohibit_test_ulimit_without_require_): Change the name
of the above function in the syntax-check rule.
* tests/cp/link-heap.sh: Use the above function to determine the
minimum memory required to run a command simpler than in the real test
run. Use that limit plus a buffer there. While at it, change to list
of commands in the subshell to fail also if the beginning `ulimit -v`
fails.
* tests/dd/no-allocate.sh: Likewise.
* tests/misc/csplit-heap.sh: Likewise.
* tests/misc/cut-huge-range.sh: Likewise.
* tests/misc/head-c.sh: Likewise.
* tests/misc/printf-surprise.sh: Likewise.
* tests/split/line-bytes.sh: Likewise.
* tests/rm/many-dir-entries-vs-OOM.sh: Likewise - doing it separately
for each program under test.

Run "make update-copyright" and then...
* tests/sample-test: Adjust to use the single most recent year.
* tests/du/bind-mount-dir-cycle-v2.sh: Fix case in copyright message,
so that year is updated automatically in future.

On most shells `:>file || framework_failure_` will not evaluate
the framework_failure_ even if there was an error writing the file.
shells which do evaluate the failure are ksh 93u+ and bash 4.2,
while shells wich don't include bash 4.3, solaris, freebsd, dash.
Furthermore this construct is problematic on Solaris 10 sh,
which will try to optimize away a `:' command in a loop
after the first iteration, even if it is redirected.
* tests/cp/link-deref.sh: Remove the leading colon on redirections.
* tests/cp/reflink-perm.sh: Likewise.
* tests/id/zero.sh: Likewise.

+ cfg.mk (sc_prohibit_colon_redirection): A new syntax check
to avoid further instances of this creeping in.

Run "make update-copyright", but then also run this,
perl -pi -e 's/2\d\d\d-//' tests/sample-test
to make that one script use the single most recent year number.

* tests/split/line-bytes.sh: Since we've limited virtual memory to
20MB, choose a smaller size, 1GiB (which is <= SIZE_MAX) rather than
1EiB, which is larger than SIZE_MAX on 32-bit systems.
I confirmed that this test still fails when the split.c-modifying
part of v8.21-58-gfec363c is backed out.

* src/split.c (line_bytes_split): Rewrite to only buffer
when necessary. I.E. only increase the buffer when we've
already lines output in a split and we encounter a line
larger than the input buffer size, in which case a hold
buffer will be increased in increments of the input buffer size.
(lines_rr): Use the more abstract xalloc_die() just like
we did in line_bytes_split(), rather than explicitly
printing the "memory exhausted" message and exiting.
* tests/split/line-bytes.sh: Add a new test for this
function which previously had no test coverage.
* tests/local.mk: Reference the new test.
* NEWS: Mention the improvement.
