While virCommandSetDryRun is used in tests only, there were some cases when error paths would not call the function with NULL arguments to reset the dry run infrastructure. Introduce virCommandDryRunToken type which must be allocated via virCommandDryRunTokenNew and passed to virCommandSetDryRun. This way we can use automatic variable cleaning to trigger the cleanup of virCommandSetDryRun parameters and also the use of the token variable ensures that all callers of virCommandSetDryRun clean up after themselves and also that the token isn't left unused in the code.
