boost-1.66 regression in ssl socket wrapper

[arvidn]

I'm wrapping my custom socket type in the boost::asio::ssl::stream wrapper. Building with boost-1.66-rc1 I get a compilation error caused by the way the ssl wrapper use read_some().

According to the documentation the function takes a MutableBufferSequence, defined here
to have a const_iterator type and begin() and end() functions, to iterate the buffer sequence.

However, in the boost-1.66-rc1 version of asio's ssl stream wrapper, it calls read_some() (here) with a boost::asio::mutable_buffer (i.e. not a sequence). It passes core.input_buffer_ which is defined here.

As far as I can tell, core.input_buffer should be of type boost::asio::mutable_buffers_1. Making this change makes my program build again.
