This patch makes unpacker_next_with_size(...), update p_bytes when
unpacker_next() returns MSGPACK_UNPACK_SUCCESS or MSGPACK_UNPACK_CONTINUE.

This new function is an extension of the original msgpack_unpacker_next()
where it now adds third argument to store the number of parsed bytes for
the returned buffer upon a MSGPACK_UNPACK_SUCCESS case.
This is useful for cases where the caller needs to optimize memory usage
in the original buffer,s so upon success retrieval of the object, it can
later deprecate the already 'parsed' bytes.
For more details about the origins of this function please refer to the
following issue on github:

msgpack_object_print used fwrite to write binary data to a stream. The intention
of the function is to produce a human-readable representation of the object for
debugging purposes. Having arbitrary data dumped as is can cause issues with
terminals that interpret it as control sequences.
This change prints printable characters as is and unprintable characters as
hex-escapes ("\xNN"). Note that UTF-8 encoded characters will now be printed as
escaped sequence of UTF-8 bytes. This is an acceptable compromise, as doing
otherwise would require a light form of UTF-8 decoding and BIN-typed objects
should not be used to transport UTF-8 strings anyway (STR should be used
instead).
In the case the target type is char[] or const char[],
If the array is '\0' teminated, msgpack-c packs the characters before
'\0', otherwise packs all characters.
When converting, the array has the size that is greater than
msgpack::object STR's size, msgpack-c adds '\0' to just after converted
characters. Otherwise msgpack-c doesn't add '\0'.
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.
