[PATCH 4/9] virDomainRedirdevDef: Introduce find & remove routines

[Michal Privoznik <mprivozn@xxxxxxxxxx>]

Basically, there are just two functions introduced here:
virDomainRedirdevDefFind which looks up given redirdev in domain
definition, and virDomainRedirdevDefRemove which removes the
device at given index in the array of devices.
