    TRAFODION-1504 check for environment in sqgen

    Avoid the common mistake of doing an sqgen in an environment that
    is not clean, where changes to CLASSPATH or other environment variables
    have been done after sourcing sqenv.sh.
    
    This commit also fixes TRAFODION-1505, delete the sw* convenience scripts
    created by install_local_hadoop when we do swuninstall_local_hadoop.

> There have been quite a few cases I've seen where we set up something (e.g. called the install_local_hadoop script) in a shell and then did sqgen in that same shell.
> What happened was that the first action should have had an impact on the CLASSPATH, but since that only happens when we source sqenv.sh and this was not done, sqgen created the wrong CLASSPATH information.
> I would like to fix that by sourcing in sqenv.sh at the beginning of the sqgen script. Also, sqenv gives the warning that the environment changed, then issue an error and abort sqgen.
