Remote desktop version 2 added a new method ConnectToEIS .
ConnectToEIS allows clients to requests a file descriptor from the
compositor which can then be used directly from libei.
Once established, the communication between compositor and application
is direct, without the need to go through the portal process(es).

The code style in the remote-desktop API is currently a mess.
While, the overall code style in mutter and gnome-remote-desktop is to
use spaces as tabulator, the remote-desktop API is mixed with both
spaces as tabulators and actual tabulators.
In addition to that, the code style in the XDG desktop portal APIs uses
spaces as tabulators as well.
To unify the code style, replace all actual tabulators with spaces.
