Add the wrapper function utils_reload_channels that unifies the channel
cleanup and channel initialization sequence required on connect,
redirect and gateway policy apply
* use dynamic logger in RDG
* honor [MS-TSGU] 2.2.9.2.1.5.2 TSG_REDIRECTION_FLAGS
* honor [MS-TSGU] 2.2.10.16 HTTP_TUNNEL_AUTH_RESPONSE
HTTP_TUNNEL_AUTH_RESPONSE_FIELD_REDIR_FLAGS flag
* add setting GatewayIgnoreRedirectionPolicy to ignore the gateway
policy if desired
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.

If freerdp_abort_connect is called, set FREERDP_ERROR_CONNECT_CANCELLED
This way freerdp_reconnect can distinguish between network issues and
user interaction and abort a retry attempt.
