Add support for CMake find_package command to msgpack. The package
exports the two targets msgpackc-static and msgpackc if shared is
enabled. The CMake find_package command works after installation
of msgpack and during build of another project which adds msgpack
as sub project via add_subdirectory command.

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.
Added lacked include files.
Added a test.
Added MSVC build settings on appveyor.
Added old MSVC workaround.
Fixed a variable definition point to meet ANSI-C.
Renamed names that related to a visitor.
Renamed test name from json to json_like because I omit escape.
Added end_map_value() and end_map() implementation.
msgpack::unpacked is a typedef of the msgpack::object_handle.
I recommend using msgpack::object_handle. It can be used not only
holding unpacked msgpack objects but also msgpack::objects that are
created by any types.
Replaced unpack() APIs in test codes and examples. They used to use old
APIs.
If MSGPACK_DISABLE_LEGACY_CONVERT is defined, msgpack::object::convert(T*) is removed.
Added MSGPACK_DISABLE_LEGACY_CONVERT to build system and documents.
Please define MSGPACK_DISABLE_LEGACY_CONVERT and update your code as follows:
Replace
int i;
obj.convert(&i); // Removed pointer version
with
int i;
obj.convert(i); // Reference version
libmsgpack.[a|so] is the library file for C++.
libmsgpackc.[a|so] is the library file for C.
Since version 1.0.0, the C++ parts of msgpack-c is a header only
library. So libmsgpack.* shouldn't be generated.
On the autotools building environment, removed libmsgpack.*
generation. On the cmake building environment, replaced libmsgpack.*
with libmsgpackc.* and set so-version to 2.0.0.
Previously the conversion would fail because struct object is not
generally provided for the const version of the type, but because
the wrapper would pass down the type unchanged, it would look for
exactly that missing template specialization unsuccessfully.
This is specifically an issue for std::reference_wrapper because
std::cref() returns an std::reference_wrapper<const T>.
