Casting to void* make gcc happy since its upset about
object types and rightly so
Fixes
'void* memcpy(void*, const void*, size_t)' copying an object of non-trivial type 'struct msgpack::v2::object' from an array of 'const msgpack_object' {aka 'const struct msgpack_object'} [-Werror=class-memaccess]

Changing the stream to `std::hex` mode should only affect the current character; otherwise printing some msgpack with a list like this: `[123, "string\\u0003", 123]` (123 decimal) ends up printing `[123, "string\\u0003", 7b]`, as `std::hex` is sticky.
MSVC CLI defined their own nullptr and provides for __nullptr for standard C++11.

msgpack-c introduce MSGPACK_NULLPTR for internal use, it is defined as __nullptr only if compiled on C++ CLI otherwise defined as nullptr.
