[libvirt] [RFC PATCH 1/4] libvirt: add VIR_DOMAIN_START_PERSISTENT flag



Added a VIR_DOMAIN_START_PERSISTENT flag for virDomainCreateXML() so
that the guest remains defined after it is destroyed. The result of
using this flag is equivilent to calling virDomainDefineXML() followed
by virDomainCreate() or virDomainCreateWithFlags().
---

Not sure if this is the correct place to add "Since 1.0.3 (likely 1.0.4)"
