Since X may point to the same MPI as either G or L (or even both), we
can't set the carry flag based on the contents of G or L after having
modified X. Instead, compute and stash the new carry value first.

Fix msb calculation. We may have to backtrack quite a bit, for
instance when subtracting two nearly equal large numbers.

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().
