Wayland implementation

Discussed in #19

Wayland with freerdp isnt that hard, we just need select between xfreerdp and the wlfreerdp command. This could happen automatically (based on env vars) or on a config field.

I would prefer to select automatically, as long as no config field is set.

Edit: fix typo

According to my findings, neither sfreerdp or wlfreerdp (3.15) work on my Gnome 48 system. However, xfreerdp works flawlessly. For now, I've only tested explorer, cmd and paint though.

@oskardotglobal I believe wlfreerdp has been deprecated in favour of developing an SDL-based cross-platform client. For now, FreeRDP runs as expected on GNOME 49 (Wayland) via xwayland.

wlfreerdp works fine on GNOME 48 (48.5), for example testing this on Fedora + Podman podman unshare --rootless-netns wlfreerdp /u:"user" /p:"MyWindowsPassword" /v:127.0.0.1 /cert:tofu launches an RDP session that works flawlessly.

Although, setting FREERDP_COMMAND to wlfreerdp in the config file ends up launching a buggy window; more specifically you can see the Windows log in UI, it loads for a bit, then it freezes. This only happens during the setup, trying the previously mentioned podman command works fine. Is winapps passing some special flags that might be causing this?

The RDP logfile

Edit: force using sdl-freerdp also works fine.

@Bilal2453 What you are doing is launching a full session, which we don't care about; we specifically need them support RAILS a.k.a. single app mode with the /app:program:<windows binary>, which they do not at the moment
