cp: add an option to only copy the file attributes
* src/copy.c (copy_attr): A new function which merges copy_attr_by_fd
and copy_attr_by_name. Also display all errors when --attributes-only
* src/copy.c (copy_reg): Skip copying the file contents if specified.
Refactor the SELinux error handling code a little and display all
SELinux errors when only copying attributes.
* src/copy.h (struct cp_options): Add a data_copy_required boolean
* src/cp.c (main): Default to copying data but don't if specified
* src/install.c: Default to copying data
* src/mv.c: Likewise
tests/cp/reflink-perm: Add a test to check that --attributes-only
does not copy data
* tests/cp/acl: Likewise. Also refactor to remove redundant
acl manipulation
* doc/coreutils.texi (cp invocation): Describe the new option
* NEWS: Mention the new feature
