Fix off-by-one bug in mpi_cmp() which could cause it to read past the
end of the buffer.

WIP: implement subtraction correctly. The actual result is now correct
most of the time, but the MSB calculation is not.

In both mpi_add_abs() and mpi_sub_abs(), make sure that the target is
untouched if the operation fails. Also ensure that A = A +/- A works.

In mpi_zero(), save a memset() if the target is already zero.

Shifting any number by zero places is a no-op, but so is shifting zero by
any number of places.

In mpi_copy(), any failure should leave the target untouched.

In mpi_load(), use be32dec() when possible.
In mpi_set(), it is impossible for the value being loaded to exceed
the minimum size of an mpi; thus, there is no need for mpi_grow().
