VS2013: new compiler warnings since v1.56.0

[lex21@…]

There are two new level 3 compiler warnings in asio, when compiling with Visual Studio 2013 x64.

1>D:\source\VS2013\libsrc\boost_1_56_0\boost/asio/detail/impl/socket_ops.ipp(1968): warning C4267: 'argument' : conversion from 'size_t' to 'int', possible loss of data

1>D:\source\VS2013\libsrc\boost_1_56_0\boost/asio/detail/impl/socket_ops.ipp(2172): warning C4267: 'initializing' : conversion from 'size_t' to 'int', possible loss of data

I have to move to 1.56 because we're moving to VS2013 and libboost-serialization doesn't work without a patch.

We have warnings as errors and don't want to turn that off. I also don't want to pollute my code with pragma warning disables.

For now, I've casted the size_t to int in the two places this warning was happening in socket_ops.ipp. Hopefully, the next release has a proper fix.
