The `uname` `-o` switch reports the operating system used. If the GNU C
standard library (glibc) is not in use, for example if musl is being
used instead, report "Linux" instead of "GNU/Linux".
Add a function that takes a user-supplied backup option and checks if it
matches any of the valid backup options. This is because GNU allows to
abbreviate backup options, as long as they are valid and unambiguous.
In case a backup option is either invalid or ambiguous, an error type is
returned that contains a formatted error string for output to the user.
The previous help string for the backup subroutines didn't comply with
the formatting found in the `--help` output of e.g. `mv` or `ln`.
Use the exact help string from these utilities instead.

This makes clap wrap the help text according to the terminal width,
which improves readability for terminal widths < 120 chars,
because clap defaults to a width of 120 chars without this feature.
This reimplements version_cmp, which is used in sort and ls to sort
according to versions.
However, it is not bug-for-bug identical with GNU's implementation.
I reported a bug with GNU here:
https://lists.gnu.org/archive/html/bug-coreutils/2021-06/msg00045.html
This implementation does not contain the bugs regarding the handling of
file extensions and null bytes.
Adds the ability to perform file backups before installing newer files on top
of existing ones. Adds a status message about backups to stdout if running in
verbose mode.

The '--backup' option would previously accept arguments separated from the
option either by a space or an equals sign. The GNU implementation strictly
requires an "equals" for argument separation.
As the argument to '--backup' is optional, the equals sign mustn't be ommited
as otherwise there is no way to tell a file argument apart from an argument
that's meant for the '--backup' option. This ensures that if '--backup' is
present it either has no further associated arguments (i.e. fallback to the
default), or the arguments are separated by an equals sign.
This adds a hidden `completion` subcommand to coreutils. When invoked with
`coreutils completion <utility> <shell>` a completion file will be printed
to stdout. When running `make install` those files will be created for all
utilities and copied to the appropriate locations.
`make install` will install completions for zsh, fish and bash; however,
clap also supports generating completions for powershell and elvish.
With this patch all utilities are required to have a publich uu_app function
that returns a clap::App in addition to the uumain function.
Gerenal numeric sort works by comparing pre-parsed floating point
numbers. That means that we don't have to store the &str the float was
parsed from.
As a result, memory usage was slightly reduced for general numeric sort.
`LANGUAGE=C` is not enough, `LC_ALL=C` is needed as the environment
variable that overrides all the other localization settings.
e.g.
```bash
$ LANGUAGE=C id foobar
id: ‘foobar’: no such user
$ LC_ALL=C id foobar
id: 'foobar': no such user
```
* replace `LANGUAGE` with `LC_ALL` as environment variable in the tests
* fix the the date string of affected uutils
* replace `‘` and `’` with `'`
Data that was previously boxed inside the `Line` struct was moved to
separate vectors. Inside of each `Line` remains only an index that
allows to access that data.
This helps with keeping the `Line` struct small and therefore reduces
memory usage in most cases.
Additionally, this improves performance because one big allocation (the
vectors) are faster than many small ones (many boxes inside of each
`Line`). Those vectors can be reused as well, reducing the amount of
(de-)allocations.
- Windows hidden file attribute determination would assume symbolic link
to be valid and would panic
- Check symbolic link's attributes if the link points to non-existing
file
