Should fix:
```
rm -rf a b c
touch a
ln -s a b
mkdir c
./target/debug/coreutils cp --preserve=links -R -H a b c
a_inode=$(ls -i c/a|sed 's,c/.*,,')
b_inode=$(ls -i c/b|sed 's,c/.*,,')
echo "$a_inode" = "$b_inode"
```
This allows other projects to construct values for these types
which in turn allows them to construct Options.

Clean up the parsing of the attributes to
preserve. There are several improvements here: Preserve now uses `max`
from Ord, the `max` method is now called `union` and does not mutate,
the parse loop is extracted into a new function `parse_iter`, the `all`
and `none` methods are replaced with const values. Finally
all fields of Attributes are now public.
prevents --preserve to eat the next argument when no value is passed.
default value for --preserve is set to mode,ownership(unix only),timestamps
before the patch:
cp --preserve foo bar
error: invalid value 'foo' for '--preserve [<ATTR_LIST>...]'
[possible values: mode, ownership, timestamps, context, link, links, xattr, all]

This commit corrects the behavior of `cp -r --parents --verbose` when
the source path is a directory, so that it prints the copied ancestor
directories. For example,
$ mkdir -p a/b/c d
$ cp -r --verbose --parents a/b/c d
a -> d/a
a/b -> d/a/b
'a/b/c' -> 'd/a/b/c'
This commit corrects the behavior of `cp --parents --verbose` when the
source path is a file so that it prints the copied ancestor
directories. For example,
$ mkdir -p a/b d
$ touch a/b/c
$ cp --verbose --parents a/b/c d
a -> d/a
a/b -> d/a/b
'a/b/c' -> 'd/a/b/c'
Fixes#3332.
Improve readability of the `preserve_hardlinks()` helper function by
reducing levels of nesting in the body of the function and making it
return a Boolean rather than mutating a Boolean argument.
When copying the contents of a named pipe (also known as a FIFO) via
cp --preserve=ownership --copy-contents fifo fifo-copy
limit the permissions of the destination file while the contents are
being copied, and then restore the permissions to match those of the
source FIFO when all contents have been copied successfully.
Prevent a panic in `cp -a` when the target of a hard link already
exists in the target directory structure.
For example,
$ mkdir -p src dest/src
$ touch src/f dest/src/f
$ ln src/f src/link
$ cp -a src dest
The `cp` command now succeeds without error.
Correct the behavior of `cp --reflink=never --sparse=always` so that
it performs a sparse copy. Before this commit, it was incorrectly
performing a dense copy.
Implement the `--copy-contents` option when the source is a FIFO, so
that the contents of the FIFO are copied (when the bytes become
available for reading) instead of the FIFO object itself. For example,
$ mkfifo fifo
$ cp --copy-contents fifo outfile &
[1] 1614080
$ echo foo > fifo
$ cat outfile
foo
[1]+ Done cp --copy-contents fifo outfile
Fix the behavior of `cp` when both `--backup` and `--force` are
specified and the source and destination are the same file. Before
this commit, `cp` terminated without copying and without making a
backup. After this commit, the copy is made and the backup file is
made. For example,
$ touch f
$ cp --force --backup f f
results in a backup file `f~` being created.
Change `cp` to terminate with an error when attempting to copy through
a dangling symbolic link with the `--force` option. Before this
commit,
touch src
ln -s no-such-file dest
cp -f src dest
would incorrectly replace `dest` with the contents of `src`. After
this commit, it correctly fails with the error message
cp: not writing through dangling symlink 'dest'
Fix a bug where `cp` failed to copy ancestor directories when using
the `--parents` option. For example, before this commit:
$ mkdir -p a/b/c d
$ cp --parents a/b/c d
$ find d
d
d/c
After this commit
$ mkdir -p a/b/c d
$ cp --parents a/b/c d
$ find d
d
d/a
d/a/b
d/a/b/c
This commit also adds the correct messages for `--verbose` mode:
$ cp -r --parents --verbose a/b/c d
a -> d/a
a/b -> d/a/b
'a/b/c' -> 'd/a/b/c'
Fixes#3332.
Before this commit, `cp -a` would terminate with a non-zero status
code on Windows because there are no extended attributes (xattr) to
copy. However, the GNU documentation for cp states
> Try to preserve SELinux security context and extended attributes
> (xattr), but ignore any failure to do that and print no
> corresponding diagnostic.
so it seems reasonable to do nothing instead of exiting with an error
in this case.
Add some additional structs and helper functions to make the code in
`copydir.rs` easier to read and maintain. This commit changes only the
organization of the code, not its function.
Refactor common code into a helper method
`Options::preserve_hard_links()`. This also eliminates the need for
mutability in a local variable in two places.
Make cp preserve the permissions of a directory when copying
it. Before this commit,
cp -pR src/ dest/
failed to copy the permissions of `src/` to `dest/`. After this
commit, the permissions are correctly copied.
