[libvirt] [PATCH 2/2] Forbid new-line char in name of new networks

[Sławek Kapłoński]

New line character in name of network is now forbidden because it
mess virsh output and can be confusing for users.
Validation of name is done in network driver, after parsing XML to avoid
problems with dissappeared network which was already created with
new-line char in name.
