Run each component in a subshell and handle errors more robustly

This commit completely rewrites keep-going mode. Instead of relying
solely on "set -e", which has some subtle limitations (such as being
off anywhere inside a conditional), use an ERR trap to record errors.

Run each component in a subshell. This way a component can set
environment variables, change the current directory, etc., without
affecting other components.
