The new 'cmd_cleanup' trigger replaces the old command_cleanup() function, which was causing linking problems on OS X and inverted strict dependency. The keyring cmd_cleanup calls keyring_free(global_keyring), instead of merely asserting keyring == NULL, so the error exit cases of many CLI functions have been simplified.
