Yukihiro "Matz" Matsumoto 69a80c94b9 mruby-bigint (mpz_and): support bit-wise and with negative numbers

Negative integers are virtually considered as 2's compliment of the
absolute value of the corresponding number. It means `-1` is considered
as infinite sequence of `1` toward msb side. ref #6314

Multi-precision Integer extension for mruby

This extension uses fgmp, which is a public domain implementation of a subset of the GNU gmp library by Mark Henderson markh@wimsey.bc.ca. But it's heavily modified to fit with mruby. You can get the original source code from https://github.com/deischi/fgmp.git. You can read the original README for fgmp in README-fgmp.md.

If you want to create your own Multi-precision Integer GEM, see examples/mrbgems/mruby-YOUR-bigint/TODO-HINT.md.
