This arises, for instance, if you want to be able to create a temporary Python
module you can import from test scripts. The Python module file MUST have the
.py extension.
Specifically:
Introduce ManageAPR class in indra/test/manageapr.h. This is useful for a
simple test program without lots of static constructors.
Extract NamedTempFile from llsdserialize_test.cpp to indra/test/
namedtempfile.h. Refactor to use APR file operations rather than platform-
dependent APIs.
Use NamedTempFile for llprocesslauncher_test.cpp.
