Created a lightweight abstraction layer so that another i/o reactor can be dropped in place of asio. The basic approach is to rename all references to asio::xxx types to openvpn_io::xxx and then make openvpn_io a preprocessor variable that points to the top-level namespace of the i/o reactor implementation. All of the source files that currently include <asio.hpp> now include <openvpn/io/io.hpp> instead: This gives us a lightweight abstraction layer that allows us to define openvpn_io to be something other than asio. Other changes: * Inclusion of asio by scripts/build is now optional, and is enabled by passing ASIO=1 or ASIO_DIR=<dir>. * Refactored openvpn/common/socktypes.hpp to no longer require asio. * Refactored openvpn/log/logthread.hpp to no longer require asio. * Added openvpn::get_hostname() method as alternative to calling asio directly. * openvpn/openssl/util/init.hpp will now #error if USE_ASIO is undefined.
