Eliminate less-than-zero checks for unsigned variables
* ext/bigdecimal/bigdecimal.c, ext/digest/md5/md5.c, ext/json/fbuffer/fbuffer.h, ext/json/generator/generator.c: Eliminate less-than-zero checks for unsigned variables. According to section 4.1.5 of C89 standard, size_t is an unsigned type. These checks were found with 'cppcheck' static analysis tool.
