Subject: check_disk: add ignore-missing option to return OK for missing fs
 There a situations where UNKNOWN or CRITICAL services are not wanted when a
 filesystem is missing, a regex does not match or the filesystem is
 inaccessible on a system. This new option helps to have the service in state
 OK.

Subject: utils_disk: add name_prev pointer to struct parameter_list

Also added handling of name_prev in np_add_parameter and np_delete_parameter.
This make calling the np_delete_parameter function easier, because it requires
the previous element as second argument.

Subject: check_disk: still allow check of available disks with ignore-missing
 param used

Also add reporting of ignored paths. When paths are provided by -p and/ or -r and
one path does not match a mounted disk, checking available disks is still
possible. Paths provided by -p are reported as ignored, when not available. Due
to code structure, this is not possible for -r unfortunately.
