0d30ad279f wayland: Separate selection buffers and other per-selection atom data
This has most notably impact in selection buffers, because those were
shared across all selection atoms. This turned out wrong on 2 situations:
- Because the selection atom was set at SelectionBuffer creation time, the
  GDK_SELECTION_NOTIFY events generated will have unexpected info if the
  buffer is attempted to be reused for another selection.
- Anytime different selections imply different stored content for the same
  target.

This is better separated into per-selection buffers, so it's not possible
to get collisions if a same target is used across different selections.

4b003a75aa wayland: Implement gdk_utf8_to_string_target
The sanitize_utf8() function has been copied from X11 so both
backends behave the same. This allows interaction with older clients
(mainly through Xwayland, and the STRING selection target) that
request non-utf8 text.

cb73becfb4 wayland: Clean up naming of GdkWaylandDisplay pointers
The naming of pointers to GdkWaylandDisplay's were inconsistent.
Running the following commands in gtk+/gdk/wayland illustrate the
inconsistency:

$ grep -r '\<display_wayland\>' *.[ch] | wc -l
195
$ grep -r '\<wayland_display\>' *.[ch] | wc -l
81

This patch renames all occurrences of "wayland_display" to
"display_wayland". This is also consistent with naming in the X11
backend. A couple of whitespace changes were done as well in places
where the rename was already done, that added line breaks to long lines
that stood out.

aaa467679d wayland: Make data_source_target() an empty stub
This request actually means nothing to the upper GDK layers,
we used to preempt a GDK_SELECTION_REQUEST event, but this is too
eager, and not like things work in X11.

Originally in wayland, this event may be used for feedback purposes.
We however don't perform any mimetype-based feedback, so we can
safely ignored.

This makes data_source_send() the only place where we actually
trigger GDK_SELECTION_REQUEST, this one is conceptually the same
than the X11 selection request event.

aad3135e4c gdk: Add GdkDragCancelReason enum as argument to GdkDragContext::cancel
We should conform to a minimal set of reasons for the gtk side to emit
a better GtkDragResult than GTK_DRAG_RESULT_ERROR. This fixes the notebook
tab DnD feature, where we rely on GTK_DRAG_RESULT_NO_TARGET.

In the wayland side, unfortunately we can't honor either NO_TARGET nor
USER_CANCELLED, we don't know of the latter, so we could return false
positives on the former.

1a394bd5ec wayland: Invert drop_finished/button release call order

0ad927adca wayland: Store requested target on GdkWaylandSelection
It doesn't make a lot of sense to have this stored as data offer data,

4f9d0c06ef wayland: Refactor selection ownership
Dissociate ownership from our maintenance of wl_data_source objects.
The only place where ownership must be updated together is
data_source.cancelled, for the other places GDK should take care of
setting up the right ownership, even if at a different order than
we'd expect here.

This fixes GTK+ apps on wayland being locally confused about the
current selection ownership. Because gtk_selection_add_targets()
results in a wl_data_source being created, and ownership being
updated right away, early callers of this will change the ownership
even if the widget it's being called on didn't explicitly request
the selection ownership yet.

de68968f89 wayland: Return the right type atom on gdk_selection_property_get()

layer helpers like gtk_selection_data_get_uris(). This fixes a crash
happening anytime a drop is attempted on a GtkPlacesSidebar.

50178ce014 wayland: Prepare against NULL selection owners on data_source requests
Currently, due to the lack of progress information in the Wayland DnD
protocol, we assume a DnD operation is finished after the first
data_source.send is finished (It's either that or leaving stuck grabs).

This however breaks previous assumptions that dest widgets can request
the data multiple times, even in response to GtkWidget::drag-motion.
This leaves us with a NULL owner for the DnD atom when we aren't
finished receiving wl_data_source events yet, causing a crash.

This commit fixes the crash, the behavior left is still far from
desirable though...

1178a0ac8b wayland: Split handling of clipboard/DnD data offers
We currently only hold the last offer received, which is wrong, as both
are independent and have different life cycles.

This means we have to store per-selection wl_data_offer and targets, and
maintain these as appropriate from the clipboard/DnD specific entry points.

342db27278 wayland: protect against unknown mimetype requests
This oddly can be reproduced with weston+weston-dnd, when dragging
anything from GTK+ into weston-dnd, it will insist on picking its
custom application/x-wayland-dnd-flower mimetype, and this request
forwarded by the compositor, even if GTK+ didn't announce it on
its wl_data_source mimetype list. (What should probably happen here
is that the request is silenced, and/or weston-dnd picks (null))

This should be harmless, we are leaking though the fd in that case,
because the emission of GdkEventSelection on an unhandled mimetype
results in NOP. In order to avoid this, we should check whether the
mimetype is supported at all on the backend code and possibly close
the fd, this involves storing these in the first place.

3bd7b2a6fb wayland: close() the selection fd if we didn't start writing yet
If the other peer requests data too fast (too rare/unlikely though),
we might receive multiple gdk_wayland_selection_request_target() calls
with no ending gdk_wayland_selection_check_write(), in which case the
fd is leaked as no GOutputStream was created to take over it.

69b5955108 wayland: Do not close the descriptor on async_write_data_free()
At the moment we create the AsyncWriteData, the ownership of the
fd is granted to the GOutputStream, and the fd set to -1, so at
this moment we're just silently getting EBADFD.

This partially reverts 25885ca600, the initialization of .fd
to -1 is valid and stays though.

6c8c37abbb wayland: Silence warnings on clipboard data sending cancellation
During copy/paste, it may be common that we receive several property changes
around the selection atom, this results in warnings when cancelling the previous

cancel silently.

69d9746708 wayland: write wl_data_offer data asynchronously
Currently writing wl_data_offer data into the fd is 1) synchronous, which
is noticeable when transferring large amounts of data, and 2) buggy, write()
error checking is done on the accumulator, breaking both the written data
accounting and error checking itself.

Fix both by making writes asynchonous through GOutputStream, the operation
is spun off and either finished, or cancelled if new data is stored in the
selection while the transfer is active.
