c5c8c7ff86 libutil/mode: Remove unnecessary octal-to-mode conversion 
The values of the file mode macros are specified explicitly by POSIX,
so we can just use the octal value directly.

b29fc0b05f chgrp: Pass -1 as the owner ID to chown(3) 
Otherwise, if the owner ID changes between stat() and chown(), we will
revert to the previous owner while changing the group.

4f1d0df755 yes: Simplify, only support one argument 
The previous code was too difficult to decipher for such a simple tool.

Since yes(1) is not specified in any standard and several well-known
implementations only support a single argument, do the same here.

Thanks to everyone who offered implementation suggestions in the
hackers@suckless.org email thread.

39f92650d3 ls, tar: Guard inclusion of sys/sysmacros.h by absence of major definition 
Since musl 1.1.23, it too does not provide `major` and `minor` through
sys/types.h, so instead include sys/sysmacros.h based on the absence of
`major` rather than only on glibc.

Thanks to Rich Felker for the suggestion.

7315b8686f which: check AT_EACCESS 
A file is executable only if the effective user
have permission to execute it. The real user's
permissions do not matter.

dc77c5968b chown/chgrp: chown target not symlink by default 
chown on a symlink should only chown the symlink itself when -h
is specified, when no options are provided the target should be chown'd.

d2824f5294 Revert "Do not use arg.h for tools which take no flags" 
This reverts commit 9016d288f1.

Tools that have no options are required by POSIX to support "--" so
that conforming applications have a way to shield their operands from
implementations that provide options as an extension.

echo(1) is just an exception, so it is handled specially.

See OPTIONS in https://pubs.opengroup.org/onlinepubs/9699919799.2018edition/utilities/V3_chap01.html#tag_17_04

01b5105e0c mkfifo: Simplify -m handling 
Rather than create the FIFO with incorrect permissions at first, then
restore with chmod(2), just clear the umask when -m is specified, and
pass the parsed mode to mkfifo(2).

99c7876310 On glibc, include sysmacros.h directly 
On glibc, major, minor, and makedev are all defined in
sys/sysmacros.h with types.h only including this for historical
reasons. A future release of glibc will remove this behaviour,
meaning that major, minor, and makedev will no longer be defined
for us without including sysmacros.h.

f45156d5b4 Simplify expression in makeline() 
This expression was wrong, but it was causing a false positive
in some compilers that couldn't see that error() cannot return.
The actual problem of the line is that it was too complex and it is better
to split it in simplex expressions.
