Changes to TLS::Callbacks for GH PR #457

Make TLS::Channel::m_callbacks a reference, so deriving from TLS::Callbacks works

Split out the compat (std::function) based interface to Compat_Callbacks.
This avoids the overhead of empty std::functions when using the virtual
interface, and ensures the virtual interface works since there is no
callback path that does not involve a vtable lookup.

Rename the TLS::Callback functions. Since the idea is that often an owning
class will pass *this as the callbacks argument, it is good to namespace
the virtual functions so as not to conflict with other names chosen by
the class. Specifically, prefixes all cb functions with tls_

Revert changes to use the old style alert callback (with no longer used data/len
params) so no API changes are required for old code. The new Callbacks interface
continues to just receive the alert code itself.

Switch to virtual function interface in CLI tls_client for testing.

Inline tls_server_handshake_state.h - only used in tls_server.cpp

Fix tests - test looked like it was creating a new client object but it
was not actually being used. And when enabled, it failed because the queues
were not being emptied in between. So, fix that.
