[PATCH 1/6][devname mangling] Move dm_task_set_newname to libdm-common.c

[Peter Rajnoha <prajnoha@redhat.com>]

Add support for device name mangling (to comply with udev whitelist) patchset.

This is a more elaborate proposal of the former patch:
 [lvm-devel][PATCH] Add support for escaping device-mapper names (to be in sync with udev whitelist)

This patch #1 is just a preparation - the dm_task_set_newname is moved from
libdm-iface.c to libdm-common.c (where the dm_task_set_name is already). These
fns will call new functions for setting the name mangling.
