gateway: multiple fixes and improvements

client/X11: support for rail (remote app) icons was added

The licensing code was re-worked: Per-device licenses are now saved on the client and used on re-connect: WARNING: this is a change in FreeRDP behavior regarding licensing. If the old behavior is required, or no licenses should be saved use the new command line option +old-license (gh#/FreeRDP/FreeRDP#4979)

Improved order handling - only orders that were enable during capability exchange are accepted. WARNING and NOTE: some servers do improperly send orders that weren't negotiated, for such cases the new command line option /relax-order-checks was added to disable the strict order checking. If connecting to xrdp the options /relax-order-checks

*and* +glyph-cache are required. (gh#/FreeRDP/FreeRDP#4926)

Fixed automount issues

Fixed several audio and microphone related issues

Fixed X11 Right-Ctrl ungrab feature

Fixed race condition in rdpsnd channel server.

Disabled SSE2 for ARM and powerpc
