the frame deletion callback would trigger far too late, allowing
crashes to occur if the selection target client exited between the
time of the drop event and the selection send event
this code is mostly copied from weston:

these files were created containing code which was very obviously copied from
weston. when copying code, copyright headers must also be copied in order to
comply with licenses.
Clipboard fds from clients are regular files, which shouldn't be passed
to fd_handler_add. Using the wrong add function causes epoll to return
immediately and we end up running idle handlers and burning cpu.

As we require wayland 1.10 now, there were missing functions for the
wl_data_source interface. This patch just adds placeholders for those
missing functions until we can implement them

Summary:
printf %m stringifies and prints errno. This is actually hugely confusing
if used in error messages after failures that don't set errno.
You may get "Success", or you may get an errno that was harmless ages
ago.
Some of the functions followed by %m have only some error paths that
set errno, or make multiple system calls that can set errno
independently - knowing the errno at failure time is unlikely to be
useful in these cases.

previously, beginning a drag with the left button, then pressing and
releasing another button would result in the drag terminating without
the original button being released
a lot of this functionality is reused from dnd. basic selection owner
management in x11 and slapping bytes down a pipe to the wl client;
a bit laggy when pasting to wl clients sometimes, need to spend more time
debugging that...

still a little rough, but the basics are functional. works by showing
the x11 compositor selection window, which has rects to exclude geometries
of xwl clients, for getting x11 xdnd events, and then manually sending
all the related client messages in order to inform the x11 client that
enlightenment is, in fact, an extremely credible xdnd drop site and not
a rogue compositor which will mangle/destroy the dnd data.
still render crashes after the operation completes, so possibly not the
most useful thing to be using now
