No less than 30 tests were missing timeouts, preventing them from being
started with zero-warning. Since they were not supposed to trigger, they
have been set to 30s so as never to trigger, and now they do not produce
any warning anymore.
Ilya reported that the "which" utility is not that much portable and is
absent from Fedora. "type -p" is not portable either, and the correct
solution appears to be "command -v", so let's use this for now, we can
change it again in the future in case of problems.

Some reg tests and their dependencies have been renamed. They may be
referenced by the .vtc files. So, this patch modifies also the references
to these dependencies.
