deprecate mp_n_root_ex and mp_expt_d_ex 
These functions were introduced to give some timing guarantees.
However the guarantees are too weak to be useful.
The functions seem to be unused essentially by downstream users.

deprecate mp_prime_is_divisible and ltm_prime_tab

deprecate mp_tc_(and|or|xor) in favor of mp_(and|or|xor) 
* same behavior for positive numbers
* generalisation for negative numbers, treating them as two complement
* improve algorithm, iterate once over the digits, manually perform two complement
* simplify mp_add_d, mp_sub_d
* functions are safe in case of a==c or b==c
* renamed mp_tc_div_2d to mp_signed_rsh (signed right shift)

make tommath_class.h and tommath_superclass.h private 
These headers are used for configuration during build time.
Therefore they shouldn't be exposed as part of the public API.

deprecate mp_get_bit 
The return type of mp_get_bit was imprecise (either mp_err or mp_bool),
therefore this function is deprecated in favor of s_mp_get_bit for now.

If we need s_mp_get_bit to be public, we should add it under a different
name. However since mp_set_bit is not available, I don't think there any
downstream users (ab)using mp_int as bitsets.

deprecate mp_prime_random_ex in favor of mp_prime_rand 
We can use the internal mp_rand generator now, since it generates
numbers which are safe for crypto purposes.

Rework handling of tunable cutoffs 
* In the default settings, a cutoff X can be modified at runtime
   by adjusting the corresponding X_CUTOFF variable.

 * Tunability of the library can be disabled at compile time
   by defining the MP_FIXED_CUTOFFS macro.

 * There is an additional file tommath_cutoffs.h, which defines
   the default cutoffs. These can be adjusted manually or by the
   autotuner.
