bf223158d0 [client] clipboard: try each clipboard until one initializes
Previously, main.c would segfault at runtime if clipboards were disabled
via cmake flags, as the clipboards array would be empty but still
indexed during initialization.

2627381021 [client] clipboard/wayland: ignore SIGPIPE from clients that hang up
Otherwise, a badly-behaving client causes Looking Glass to receive a
SIGPIPE during Wayland copy operations. Handle EPIPE at call-sites
instead.

c9f41ea69e [client] fix ignoreQuit on Wayland
On Wayland, SDL_WINDOWEVENT_CLOSE is sent even when exiting with keyboard
shortcuts. This meant that the client is still closed even with -Q.

We now swallow SDL_WINDOWEVENT_CLOSE if the cursor is inside the VM. This
should prevent keyboard shortcuts from closing the client, while still
allowing the window to be closed by clicking X with the mouse per #138.
