stack.sh invokes some helper scripts as separate processes, rather than by source'ing them. As with stack.sh itself, abort immediately on the first error, so that errors don't compound and result in confusing error messages. If one of these helper scripts aborts, stack.sh itself will also abort in the usual manner. Due to the change in behaviour, tweak some mv invocations to ensure that they don't trigger false failures. As with stack.sh itself, also enable xtrace so we can see exactly what's happening. In particular this allows us to see the cause of any premature termination due to a command failing whilst errexit is enabled. Change-Id: I7a55784c31e5395e29ab9bbe2bb112b83b9be693
