* mpi-patches/add-mp-hash (mp_hash): Fixed use of uninitialized
variable on platforms where the MP digit is smaller than a long integer.
(Not anything TXR is known to run on). Changed algorithm to take the
first and last digit and add them together, rather than just taking the
last digit. The last digit will be zeros for numbers that contain 2 as a
factor with a large enough multiplicity.
* mpi-patches/add-mpi-toradix-with-case: Refreshed.
* mpi-patches/bit-search-optimizations: Likewise.
* mpi-patches/faster-square-root: Likewise.
* mpi-patches/fix-bad-shifts: Likewise.
* mpi-patches/fix-mult-bug: Likewise.
