tr detects if a class in set2 is matched by a class at the correct position in set1 after it has expanded everything before the class in both sets:
So
tr 'abcd[:upper:]' 'a-d[:lower:]'
should not fail
OpenBSD uses the original utmp file format so the general `users` does not
work there. By using the `utmp-classic` lib, we cna process the current users
on the system from the /var/run/utmp and show the list.
fixes#5665
If there is a [:lower:] or [:upper:] in set2, then there must be a [:lower:] or [:upper:] at the
same logical position in set1
So
tr -t [:upper:] [:lower:] works
tr -t 1[:upper:] [:lower:] doesnt
We have 3 different kinds of input:
* "algo (filename) = checksum"
example: `BLAKE2 (a) = bedfbb90d858c2d67b7ee8f7523be3d3b54004ef9e4f02f2ad79a1d05bfdfe49b81e3c92ebf99b504102b6bf003fa342587f5b3124c205f55204e8c4b4ce7d7c`
* "checksum filename"
example: `60b725f10c9c85c70d97880dfe8191b3 a`
* "checksum filename"
example: `60b725f10c9c85c70d97880dfe8191b3 a`
These algo/regexp are tricky as files can be called "a, " b", " ", or "*c".
We look at the first time to analyze the kind of input and reuse the same regexp then.
Summary of the change:
* Move the common code into checksum
* Create a structure HashAlgorithm to handle the algorithm (instead of the 3 variables)
* Use the same function for cksum & hashsum for --check (perform_checksum_validation)
* Use the same for function for the hash generation (digest_reader)
* Add unit tests
* Add integration tests
* Fix some incorrect tests
* env: adds --ignore-signal

The test_cp and test_mv have xattr related tests. They should
be disabled on OpenBSD after commit 19d42c0339 disabled the
compare_xattrs function on OpenBSD.
Fixes#6348
The test_compare_xattrs test fails on OpenBSD because OpenBSD does
not support xattrs. Disabling this function and its test for
target_os = openbsd resolves the issue.
Fixes#6348
An additional issue was found while reviewing #6340, check [this thread][1]. A summary is:
- `tr` ignores the `-t`/`--truncate-set1` flag when not translating
- Not translating is defined as `-d` was passed, or one set was passed.

Fixes#6163 and adds a test to verify that a regression is not caused.
Instead of inverting the conditions to check (e.g. delete characters **not** present in set1) invert
set1 when passed the complement flag (`-c`, `-C`, `--complement`). This is done by calculating set1
then "inverting" it by subtracting from the "full" (universe) set (0..=u8::MAX).
This fixes issue 6163 because it was caused by a combination of the `-c` and `-t` flag. `-c` is the
abovementioned complement flag and `-t`/`--truncate-set1` truncates set1 to the length of set2. What
happened in issue 6163 is that `set1={b'Y'}` and `set2={b'Z'}`, when truncated set1 stays the same
and we proceed. The problem is GNU utils does not consider set1 to be `{b'Y'}`, but the complement
of `{b'Y'}`, that is `U \ {b'Y'}={0, 1, ..., b'X', b'Z', ...}`, thus it is truncated to `{0}`.
We can verify this by doing: `printf '\0' | tr -c -t Y Z`, which prints `Z` to stdout as expected.
Additionally, by calculating the complement of set1 we no longer need to consider the complement
flag when doing the translate operation, this allows us to delete a lot of code.
