[libvirt] [PATCH v3 02/11] util: netlink: define cleanup function using VIR_DEFINE_AUTOPTR_FUNC

Using the new VIR_DEFINE_AUTOPTR_FUNC macro defined in src/util/viralloc.h, define a new wrapper around an existing cleanup function which will be called when a variable declared with VIR_AUTOPTR macro goes out of scope. Also, drop the redundant viralloc.h include, since that has moved from the source module into the header. This commit also typedefs virNlMsg to struct nl_msg type for use with the cleanup macros. When a variable of type virNlMsg * is declared using VIR_AUTOPTR, the function nlmsg_free will be run automatically on it when it goes out of scope.
