* Allow the same type for number_integer_t and number_unsigned_t basic_json did not compile with NumberUnsignedType == NumberIntegerType because overloads on both types collided. Such a basic_json now stores every integer as number_integer: the colliding overloads take a placeholder type, unsigned C++ integers are converted to number_integer_t, and value_t::number_unsigned maps to number_integer. Also fixes two problems this configuration would hit: the unsigned integer parser accepted values that wrap around to negative numbers, and dump() overflowed when computing the absolute value of the minimum. A repeated NumberFloatType gets a static_assert.

MSVC rejected it as a recursive alias declaration and GCC 4.9, 5 and 7 crashed with an internal compiler error. basic_json now uses number_unsigned_overload_type<NumberIntegerType, NumberUnsignedType>, which also makes the GCC 5 workaround in the patch test unnecessary. Infer reported a null dereference for the number_unsigned case in from_json, which cannot happen for a basic_json whose number_unsigned_t is number_integer_t; assert it.
