This patch follows the pattern used in qemu driver regarding reference counting. It changes lxcDomObjFromDomain() to ref the domain (using virDomainObjListFindByUUIDRef()) and adds virDomainObjEndAPI() which should be the only function in which the return value of virObjectUnref() is checked. This makes all reference counting deterministic and makes the code a bit clearer. Signed-off-by: Katerina Koukiou <k.koukiou@gmail.com>
