d13879f862 [ruby/bigdecimal] Read version from bigdecimal.c 
The dependency of extconf.h on bigdecimal.gemspec does not make sense
as far as no rule is defined for it.  Also, the relationship between
extension library and gemspec file is various in default gems, and
does not work well.

[ruby/bigdecimal] Fix negative Bignum conversion 
Introduced in 4792a917d8

`rb_absint_size` return the number of bytes needed to fit
the absolute integer, but negative integers need the sign, so one more
bit, and potentially one more byte.
