Variadic function for multiplications with mpz_t

[Ha T. Lam]

​Unfortunately, there are a lot of GMP functions that are not available
with ​the wrapper class, e.g. invert, gcd, nextprime, (non-negative) mod,
etc. I end up converting between the C++ class and the C functions so often
that I decided to go with the C functions instead, despite being not very
comfortable with C.
