53ac6c5c98 - Change mpi private function s_mp_mul_d_add_offset into a macro. 
- Declare and implement new function s_mp_mul_add, which is a candidate
  for replacement with assembler code.
- Convert mp_mul, mp_sqr, etc. to use s_mp_mul_add.
- New implementation of mp_invmod for odd moduli. Algorithm from paper
  "Fast Modular Reciprocals" by Richard Schroeppel (a.k.a. Captain Nemo).
- New function s_mp_invmod_32b in mpi.c, computes inverse mod 2**32, also
  from same paper. Used in mp_invmod and mp_exptmod.

0bade04ba3 Platform independent performance enhancements to functions that multiply, 
square, subtract, right shift, compare, mul_d_add_offset.  This lib's
Modular Exponentiation performance now compares favorably with most (not
all) other open source bignum libs on IRIX/R5000.  No assembler code is
presently being used.  Comparison on other platforms will now commence.

26a0e342f4 - Implement s_mp_mul_2d, which complements s_mp_div_2d. 
- Rewrite and speed up mp_sqr, most-frequently used in mp_exptmod().

886543402f Reduced the number of temporary variables allocated and freed during a 
modular exponentiation by over 99%.  Modified mp_mul and mp_sqr to only
allocate temporary variables when absolutely needed.  Changed mp_copy
and mp_init_copy to allocate space according to the amount allocated
in the source, reducing the need to grow the variable later.

385fd4fc86 - Renamed mp_exptmod to s_mp_exptmod. This function is now used only in 
when the modulus is even. mp_exptmod is now in mpmontg.c.
- Declare and define new function s_mp_mul_d_add_offset(), which computes
the product of an mp_digit and an mp_int, shifts the product to the left
by a number of digits, and adds the shifted product to another mp_int.
Used in multiplication and Montgomery reduction.  Numerous platform
vendors have assembly language versions of this function.
- Removed some ANDs with DIGIT_MAX.  Casting to mp_digit is necessary
and sufficient.  The AND doesn't help.
