The patch implements the missing memory control APIs for lxc, i.e., domainGetMaxMemory, domainSetMaxMemory, domainSetMemory, and improves domainGetInfo to return proper amount of used memory via cgroup. * src/libvirt_private.syms: Export virCgroupGetMemoryUsage and add missing virCgroupSetMemory * src/lxc/lxc_driver.c: Implement missing memory functions * src/util/cgroup.c, src/util/cgroup.h: Add the function to get used memory
