Made it easier to debug generated test files

Browse Source 
Added internal lineno tracking of generated test files so that test.py
can reset the generated #line directives after a test case. This helps
debug issues with the generated glue code itself, which would previously
end up with invalid/unhelpful lineno information in error messages.

Also changed suffix from .c.t to .tc
