This PR creates a new /gateway:type:arm transport.
It depends on CJSON
The arm transport is not a transport by itself but is responsible
for getting the websocket endpoint from a configuration url derived from
the configured gateway host in the rdpw file or cmdline
* factor out most websocket specific code parts into websocket.c
* create wst.c (Websocket Transport) as gateway transport implementation
* introduce GatewayUrl setting that holds the websocket url
* introduce GatewayHttpExtAuthBearer that holds the HTTP Bearer
* GatewayHttpExtAuthBearer can be used by both rdg and wst
The client tries to connect using RDSTLS only when it has received a
server redirection PDU with LB_PASSWORD_IS_ENCRYPTED flag.
The server exposes RDSTLS on negotiation if it has been configured on settings.
Then authenticates a client using configured credentials from settings:
RedirectionGuid, Username, Domain, Password.
Currently if the authentication callback returns `FALSE` the utils
function handle this as scenario as no credentials provided (returns
`AUTH_NO_CREDENTIALS)`.
This PR introduces a new `auth_status` called `AUTH_CANCELLED` that is
returned if the authentication callback returns `FALSE`. If the callback
returns `TRUE` and username or password are empty the util function will
continue to return `AUTH_NO_CREDENTIALS`.
THe PR also fixes some incorrect returns in RPC over HTTP gateway code.
We no longer have a blocking polling loop in transport. Instead assume
there is more data after a packet was processed and let the transport
try again. If there is another packet ready, this repeats until only a
partly received (or no new data available) situation is reached.
With the latest client changes the internal event loop requires a handle
to wait on. Add a new function to (re)set the newly added transport event handle.
Up to this commit the client and server state machine handling used
different return values for state machine changes.
This is fixed with this commit:
* Use common enum return values
* Use common helper functions
Set the same keepalive properties to accepted server socket as are set
to client sockets. This prevents the server from keeping sockets open
for tens of minutes in case the client disappears.
