The 'domrename' command needs to check if the new domain name contains
the slash character. This character is not accepted by libvirt XML
definition because it is an invalid char (see Cole's commit b1fc6a7b7).
This commit enhace the 'domrename' command adding this check.

Slash in VM name may be allowed for some hypervisors and when defining
the hypervisor defines this via VIR_DOMAIN_DEF_FEATURE_NAME_SLASH parser
feature flag.

Currently it appears that virtualbox, phyp, vmx, and xenapi driver
support a slash so the fix below is wrong as it would forbid the slash
when renaming the VM for those drivers.

This needs to be implemented in the qemu driver according to the BZ.

Hi Peter,

I read the BZ comments and Cole's suggestion, but I didn't know about
the requirements of the other hypervisors.
Since slash is commonly used for paths.

I will investigate it properly.
