Yes

IMHO, clipboard.[ch] should handle clipboard code as much as
possible; considering that this change is not too big, I think it
is worth the effort.
e.g: if we add wayland/windows backend besides x11/gtk, the code
to be changed would be clipboard.[ch] instead of vdagent.c. Of
course, I really hope that gtk would be enough for x11/wayland
and even windows if we get this to be mingw buildable.

Probably auto would set to --with-gtk-clipboard to yes as the
only dependency is gtk which we already depend on... but in case
of issues, one could switch off, at least in the next release.

Ah, right. Yes, a boolean might make it clear on why you are
changing the pointer.

if agent->conn was not needed, you could perhaps:
g_clear_pointer(&agent->clipboards, vdagent_clipboards_finalize);
But I understand that it is needed so you can ignore my comment
