This is meant to help with the following scenario: main thread
creates secondary threads, each secondary thread asks the context
store for its own context, then goes into a "forever" scheduling
loop. Main thread waits for the secondary threads to finish, and
owns the context store. It would be nice to be able to have yet
another thread (say, a SIGINT handler) be able to call .stop()
on all the contexts managed by the context store, thus being able
to end the loops in the secondary threads and allow the main
thread to exit.

with the new C++17 capability of inline for variables, we can avoid
having to ifdef tricks to only include the variables into one compilation
unit. Also remove the extern.hpp that serves no purpose now anymore.

This is the result after running 'clang-format -i' on all C++ files and
headers, with the defined formatting rules in .clang-format.
Only the openvpn/common/unicode-impl.hpp has been excluded, as that is
mostly a copy of an external project.

Calling close() on one side makes shutdown() call on another
side throw an exception "socket is not connected".
Shutdown functionality is not required for agent and
hence disabled for UDS and macOS case.
This fixes OVPN3-500.

* Added native_handle() virtual method
* Use AltRouting abstract socket when
OPENVPN_POLYSOCK_SUPPORTS_ALT_ROUTING is defined

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.
