Revert "lib/mpi: Extend the MPI library"
This partially reverts commit a8ea8bdd9df92a0e5db5b43900abb7a288b8a53e.
Most of it is no longer needed since sm2 has been removed. However,
the following functions have been kept as they have developed other
uses:
mpi_copy
mpi_mod
mpi_test_bit
mpi_set_bit
mpi_rshift
mpi_add
mpi_sub
mpi_addm
mpi_subm
mpi_mul
mpi_mulm
mpi_tdiv_r
mpi_fdiv_r
