Description

The suite currently maintains a list of variables set to absolute paths of commands used in the suite. There are several difficulties with this setup.

1. It doesn't constrain the set of allowable commands. New tests can alway introduce a utility directly, bypassing the current mechanism.
2. It leads to errors where $COMMAND is used, but not defined.
3. A variable referring to a command can be overriden (think `export FILE=/tmp/foo`)

Solution: =========
During test initialization, create a directory and add symlinks to wanted commands inside. Before test execution, set $PATH to be only that directory. Users can still bypass this mechanism by specifying an absolute path, but it's no longer easy to do it accidentally.
