all: add broken pipe detection while waiting for input
When a program's output becomes a broken pipe, future attempts to write
to that ouput will fail (SIGPIPE/EPIPE). Once it is known that all
future write attepts will fail (due to broken pipes), in many cases it
becomes pointless to wait for further input for slow devices like ttys.
Ideally, a program could use this information to exit early once it is
known that future writes will fail.
Introduce iopoll() to wait on a pair of fds (input & output) for input
to become ready or output to become a broken pipe.
This is relevant when input is intermittent (a tty, pipe, or socket);
but if input is always ready (a regular file or block device), then
a read() will not block, and write failures for a broken pipe will
happen normally.
Introduce iopoll_input_ok() to check whether an input fd is relevant
for iopoll().
Experimentally, broken pipes are only detectable immediately for pipes,
but not sockets. Errors for other file types will be detected in the
usual way, on write failure.
Introduce iopoll_output_ok() to check whether an output fd is suitable
for iopoll() -- namely, whether it is a pipe.
iopoll() is best implemented with a native poll(2) where possible, but
fall back to a select(2)-based implementation platforms where there are
portability issues. See also discussion in tail.c.
In general, adding a call to iopoll() before a read() in filter programs

rm: --dir (-d): fix bugs in handling of empty, inaccessible directories
* src/remove.c (prompt, rm_fts): In the dir-handling code of both of
these functions, relax a "get_dir_status (...) == DS_EMPTY" condition
to instead test only "get_dir_status (...) != 0", enabling flow control
to reach the prompt function also for unreadable directories. However,
that function itself also needed special handling for this case:
(prompt): Handle empty, inaccessible directories properly,
deleting them with -d (--dir), and prompting about whether to delete
with -i (--interactive).
* tests/rm/empty-inacc.sh: Add tests for the new code.

tests: port chmod/setgid.sh to macOS 12

in case id -g returns 4294967295 (nogroup) which is special

tests: port better to macOS group numbers
* init.cfg (groups): Port better to macOS 12, where
group 4294967295 (nogroup) is special: you can be a member
without being able to chgrp files to the group.
* src/copy.c: Some changes if HAVE_FCLONEFILEAT && !USE_XATTR.
(fd_has_acl): New function.
(CLONE_ACL): Default to 0.
(copy_reg): Use CLONE_NOFOLLOW to avoid races like CVE-2021-30995
<https://www.trendmicro.com/en_us/research/22/a/
analyzing-an-old-bug-and-discovering-cve-2021-30995-.html>.
Use CLONE_ACL if available and working, falling back to cloning
without it if it fails due to EINVAL.
If the only problem with fclonefileat is that it would create the
file with the wrong timestamp, or with too few permissions,
do that but fix the timestamp and permissions afterwards,
rather than falling back on a traditional copy.

cp: simplify infer_scantype
* src/copy.c (infer_scantype): Do not set *SCAN_INFERENCE
when returning a value other than LSEEK_SCANTYPE.
This is just minor refactoring; it simplifies the code a bit.
Callers are uneffected.
