libblkid: (ntfs) validate that sector_size is a power of two

The NTFS prober reads data based off an offset of the sector size.
If the sector size is unaligned and the read data is cached then other
probers can read unaligned values.

Sector sizes for NTFS actually only make sense as power-of-two so
validate that and as a sideeffect avoid the unaligned reads.

Also add the reproducer from OSS-Fuzz that found this issue.

Fixes #2509

Do not modify permissions on possible files. Instead, retrieve

BUFSIZ can vary quite a bit  e.g. glibc/linux systems its 8192

tests: (lsfd) avoid race conditions (part 1)

For terminating test_mkfds process, the test cases
used SIGCONT. test_mkfds used pselect for waiting for the signal.
After receiving the signal test_mkfds exited.

There is a race condition in this logic. If a test case sends SIGCONT
to test_mkfds process before the process calls pselect, the signal
may be lost. As the result, test_mkfds keeps waiting forever in pselect.

This change replaces the code sending SIGCONT with writing to the pipe
connecting to the stdin of test_mkfds. test_mkfds also monitors
its stdin in the pselect call. Unlike the signal, the written bytes to
the pipe are queued.

This change doesn't touch tests/ts/lsfd/option-inet and option-summary
test cases. They don't use coproc. So fixing the race condition in the test
cases can be much complicated. I will make a dedicated pull request (part 2)
for them.

tests: (test_mkfds) monitor stdin by default

After making file descriptors as specified in arguments, test_mkfds
waits for an event with pselect. When test_mkfds gets the event, it
exits.

The original code monitored stdin when the test_mkfds process ran in
the foreground. However, monitoring stdin is useful even when it runs
in the background. ts/lsfd/mkfds-* test cases run test_mkfds as a
co-process.  So the test cases can terminate their test_mkfds
processes with echo command if the processes monitor stdin.

This change also adds -X/--dont-monitor-stdin option. As the name
shows, with the option, test_mkfds doesn't monitor stdin as before.
Some test cases run test_mkfds directly. In such a case,
tests/functions.sh may connect stdin of test_mkfds to
/dev/null. /dev/null is always ready to be read.

Daan De Meyer [Sun, 20 Aug 2023 09:42:51 +0000 (11:42 +0200)] 
Add new setpgid utility

This program allows running a command in a new process group and
optionally makes the new process group the foreground process group
of the ctty.

This is useful when running programs through wrappers programs (think
bubblewrap, ...) and wanting to make sure that SIGINT is only sent to
the innermost process. This is possible by putting the innermost process
in a new process group and making that process group the foreground process
group of the controlling terminal.

By adding a separate utility to util-linux, we can apply this to any
program even if the program itself doesn't implement this functionality.
