[PATCH 14/19] test: Add functions to find the amount of allocated memory

[sjg at google.com]

The malloc() implementations provides a way of finding out the approximate
amount of memory that is allocated. Add helper functions to make it easier
to access this and see changes over time. This is useful for tests that
want to check if memory has been allocated or freed.
