Replace make_shared with new in some cases

[stefan-floeren]

Replace make_shared for asio types that take a lib::ref as a parameter.
This should fix the ASIO change (boostorg/asio@59066d8) for 1.70,
while keeping it backwards compatible to older boost versions.

Fixes #794
Fixes #808

When building against boost 1.70, our team still had issues with the lib::ref on endpoint.hpp line 856. Removing the lib::ref allowed it to compile for us.

Here is what we changed it to.
m_resolver = lib::make_shared<lib::asio::ip::tcp::resolver>(*m_io_service);

Sorry, missed to add those. Should be fixed now.

For the reasoning between new and make_shared, check boostorg/asio@59066d8#commitcomment-32667434 and following.

I cite the linked comment:

That won't work with boost::make_shared and pre-C++11 compilers. On those compilers make_shared forwards parameters by const reference
