@brief Test case generation functions
@fixme Update the following
The following components are generated.
test_common.[ch]: A collection of common code for tests. Currently
this includes the ability to set the scalar members of an object with
incrementing values and then similarly verify those values
test_scalar_acc.c: Instantiate each type of object, then set and get
scalar values in the objects.
test_list.c: Instantiate each type of list, add an element of each
type the list supports, setting scalar values of the elements.
test_match.c: Various tests for match objects
test_msg.c: Instantiate top level messages
These will move towards unified tests that do the following:
Create or init an object.
Populate the object with incrementing values.
Possibly transform the object in some way (e.g., run the underlying
wire buffer through a parse routine).
Verify that the members all have the appropriate value
Through out, checking the consistency of memory and memory operations
is done with mcheck (if available).
