ASADT-21 Linux Thin Core Library tests have compiler warnings.

For some .xml input there were instances of unused variables and
functions which caused there to be warning. These were removed.

Some instance of this were when there were unsupported data types in the
.xml. Some of these tests were removed from tl_test.py rather than fix
the code generator at this time.
