Janos Follath c8d66d50d0 mpi_exp_mod: reduce the table size by one 
The first half of the table is not used, let's reuse index 0 for the
result instead of appending it in the end.

Janos Follath 060009518b mpi_exp_mod: fix out of bounds access 
The table size was set before the configured window size bound was
applied which lead to out of bounds access when the configured window
size bound is less.

Janos Follath 9c09326572 mpi_mod_exp: be pedantic about right shift 
The window size starts giving diminishing returns around 6 on most
platforms and highly unlikely to be more than 31 in practical use cases.
Still, compilers and static analysers might complain about this and
better to be pedantic.

Janos Follath 3646ff02ad mpi_exp_mod: move X next to the precomputed values 
With small exponents (for example, when doing RSA-1024 with CRT, each
prime is 512 bits and we'll use wsize = 5 which may be smaller that the
maximum - or even worse when doing public RSA operations which typically
have a 16-bit exponent so we'll use wsize = 1) the usage of W will have
pre-computed values, then empty space, then the accumulator at the very
end.

Move X next to the precomputed values to make accesses more efficient
and intuitive.

Janos Follath 844614814e mpi_exp_mod: remove memory ownership confusion 
Elements of W didn't all have the same owner: all were owned by this
function, except W[x_index]. It is more robust if we make a proper copy
of X.

Janos Follath b764ee1603 mpi_exp_mod: protect out of window zeroes 
Out of window zeroes were doing squaring on the output variable
directly. This leaks the position of windows and the out of window
zeroes.

Loading the output variable from the table in constant time removes this
leakage.
