9eecab7b49 print jenkins seed on startup 
I just had a case around where the `mp_prime_rand()` testcase failed
but I couldn't reproduce.
I'm pretty sure that was caused by all my changes and partial rebuilds
but anyways it'll give us in the future the possibility to debug such
a case.

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 
* it is an implementation detail used for prime testing
* there is upcoming work by @czurnieden regarding a generalised prime sieve
* furthermore remove jacobi test (replaced by kronecker)

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 mp_word private 
mp_word is an internal type and it is problematic if it is exposed
in the public api. See for example #216 - MSVC does not support 128 bit
mp_words. But it is perfectly ok to use those internally in the library,
as long as the library is compiled with GCC.

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.

* add CONV_WARNINGS and enable the warnings only for clang-7 (for now)
* disable Wsystem-headers if Wconversion is enabled, to avoid warnings from the system headers
