Persist HTTP peer io_service::work lifetime:
This simplification eliminates any potential for bugs caused by incorrect
lifetime management of the io_service::work object.
De-pimpl HTTP::Server
Rename ServerImpl data members
Tidy up HTTP::Port interface
Fix block on ~Door for pending objects
Always detect ssl in HTTP server
Add new Handler interfaces
Add HTTP::Writer interface:
The Writer interface allows clients to supply a "pull" style object to provide
responses to HTTP Requests. The interface is designed to support a coroutine
based implementation.
Split implementation into three headers
Use ssl_bundle in SSLPeer
Call HTTP Handler with legacy peer handshake
Construct Overlay::Peer with ssl_bundle and legacy handshake
Pass legacy peer handshakes through Overlay
Add doors section in cfg
Add [doors] parsing code
Rename to legacy_context
Pass Config in setup_RPC
Remove unused struct
Check port protocol in legacy handshake detect
Use port settings in ssl detection
