qapi: fix error propagation
Don't overwrite / leak previously set errors. Make traversal cope with missing mandatory sub-structs. Don't try to end a container that could not be started. v1->v2: - unchanged v2->v3: - instead of examining, assert that we never overwrite errors with error_set() - allow visitors to set a NULL struct pointer successfully, so traversal of incomplete objects can continue - check for a NULL "obj" before accessing "(*obj)->has_XXX" (this is not a typo, "obj != NULL" implies "*obj != NULL" here) - fix start_struct / end_struct balance for unions as well Signed-off-by: NPaolo Bonzini <pbonzini@redhat.com> Signed-off-by: NLaszlo Ersek <lersek@redhat.com> Signed-off-by: NStefan Hajnoczi <stefanha@linux.vnet.ibm.com>
