Peter Krempa 0dffca8f95 virCommandSetDryRun: Rework resetting of the dry run data
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.
