Version 0.20.0

Raised minimum libmicrohttpd requirement to 1.0.0.
Migrated Basic Auth to v3 API (MHD_basic_auth_get_username_password3,
MHD_queue_basic_auth_required_response3) with UTF-8 support.
Migrated Digest Auth to v3 API (MHD_digest_auth_check3,
MHD_digest_auth_check_digest3, MHD_queue_auth_required_response3)
with SHA-512/256 support, userhash, nonce binding, and structured
digest_auth_result enum. Default algorithm changed to SHA-256.
Added new response types: empty_response, pipe_response, iovec_response.
Added external event loop integration: webserver::run(), run_wait(),
get_fdset(), get_timeout(), add_connection().
Added daemon management: quiesce(), get_listen_fd(),
get_active_connections(), get_bound_port().
Added daemon options: listen_backlog, address_reuse,
connection_memory_increment, tcp_fastopen_queue_size,
sigpipe_handled_by_app, https_mem_dhparams, https_key_password,
https_priorities_append, no_alpn, client_discipline_level.
Added startup flags: no_listen_socket, no_thread_safety, turbo,
suppress_date_header.
Added WebSocket support (conditional on HAVE_WEBSOCKET):
websocket_handler, websocket_session, register_ws_resource().
Added utility functions: reason_phrase(), is_feature_supported(),
get_mhd_version().
Added example and documentation for serving binary data from memory
using string_response (addresses PR #368).
Added conditional compilation for basic auth (HAVE_BAUTH), mirroring
