Jens Remus f4b2da6c9d util_path: Add functions to test path is read/write-only ...

For root the functions util_path_is_readable() and util_path_is_writable()
do not take the path's permissions into account. The function access()
succeeds as root is allowed to read/write any file regardless of its
permissions.

Introduce the functions util_path_is_readonly_file() and
util_path_is_writeonly_file() to test whether a path is a regular file and
is either read-only (neither user, group, nor other have write permission,
but one or more of user, group, and other have read permission) or
write-only (neither user, group, nor other have read permission, but one
or more of user, group, and other have write permission).
