Add two test cases for shortcut logic used when one operand is zero and
...
the other is also the target.

Fix a bogus t_malloc_fail in one of the mpi_add_abs() tests.
...
Add several subtraction test cases and modify some others to better
exercise the carry logic, which is far more complex for subtraction than
for addition.
Add test cases where the target is the same MPI as one or both operands.

Remove the "trailing garbage" version of the mpi_cmp() test. It would
...
be better to systematically pad MPIs used in all tests with garbage.
Greatly expand the number of mpi_cmp() tests to cover all possible
combinations of same or different sign, same or different msb and same
or different magnitude.

Fix the "x = a + b" allocation failure test. Since a and b were
...
equal, mpi_sub_abs() would return early and the test would never
exercise the mpi_grow() call which is intended to fail.

Add tests for the off-by-one bug we just fixed in mpi_cmp_abs().

Add a few tests for subtraction. They're not particularly well thought
...
out, because currently subtraction does not work at all, but they work
well enough in the sense that they fail with the current implementation.

Add numerous tests, mostly for allocation failures and edge conditions.
...
Add a t_compare_mpi() predicate which checks that two MPIs have the same
value (but not necessarily the exact same representation).
Clean up and improve existing tests.

It appears that gcc does not accept partial struct initialization. Add
...
a CRYB_MPI_ZERO macro that expands to an all-zeroes initializer.

Previous commit was incomplete. Add missing prototypes and a test case.

Add a test function for comparison operators (but no test cases yet).
...
Consistently destroy MPIs after use.
