Push SoupContext into the background in preparation for itssoup-refactoring

	eventual removal.

	* libsoup/soup-message.c (soup_message_new,
	soup_message_new_full): Take a SoupUri instead of a SoupContext
	(soup_message_set_uri): instead of set_context
	(redirect_handler): Use soup_message_set_uri
	(soup_message_get_context): gone

	* libsoup/soup-context.c (struct _SoupContext): Move this here. No
	one else needs to know.
	(soup_context_get): Gone
	(soup_context_from_uri): constify uri
	(get_proxy): moved here from soup-misc.c and made to return a
	SoupUri.
	(try_create_connection): Update for that.

	* libsoup/soup-private.h: Remove struct _SoupContext def

	* libsoup/soup-connection.c (soup_connection_new): constify uri

	* libsoup/soup-proxy-connection.c (soup_proxy_connection_new):
	constify uri arguments, remove SoupContext references

	* libsoup/soup-misc.c (soup_get_proxy): Gone

	* libsoup/soup-server-cgi.c (run_async): Use soup_message_set_uri, etc

	* libsoup/soup-server-tcp.c (read_headers_cb): Likewise

	* tests/*: update soup_message_new() calls
