[PATCH v2 1/2] ui/gtk: detach_all option for making all VCs detached upo


From: Dongwon Kim
Subject: [PATCH v2 1/2] ui/gtk: detach_all option for making all VCs detached upon starting
Date: Mon, 26 Jul 2021 14:52:46 -0700

With "detach-all=on" for display, all VCs are detached from the beginning.
This is useful when there are multiple displays assigned to a guest OS.

v2: Move "detach-all" option to under DisplayGTK as it's GTK specific
