We might fail to page flip a new buffer, often after resuming, due to the FIFO being full. Prior to this commit, we handled this by switching over to plain mode setting instead of page flipping. This is bad because we won't be synchronized to the refresh rate anymore, but just the clock. Instead, deal with this by trying again until the FIFO is no longer full. Do this on a v-sync based interval, until it works. This also changes the error handling code for drivers not supporting page flipping to rely on them returning -EINVAL. The handling is moved from pretending a page flip working to explicit mode setting in meta-renderer-native.c. Fixes: https://gitlab.gnome.org/GNOME/mutter/issues/460
