f5e68711d0 [client] wayland: handle wl_data_source.target action
There is no action to be taken by the Looking Glass client, but a
handler needs to exist as certain other Wayland clients chooses to
send this message for copy-paste operations despite the fact it's
supposed to be used for drag-and-drop negotiation.

6419279c3c [client] wayland/clipboard: prefer text/plain over text/html
When both text/plain and text/html are available, we should prefer the plain
text as we can't paste HTML.

7f5f46c448 [client] wayland: offer all supported clipboard formats
This commit restructures the Wayland clipboard handling for host->VM.

Before, we select one clipboard format and buffers the data for it, to
be presented to spice when needed.

Now, we simply offer all clipboard formats supported, and only when spice
asks for the data do we actually read the wl_data_offer. The wl_data_offer
is kept around until a new offer is presented, the offer invalidated, or
when we lose keyboard focus. This is in accordance with the specification
for wl_data_device::selection, which states that:

> The data_offer is valid until a new data_offer or NULL is received or
> until the client loses keyboard focus. The client must destroy the
> previous selection data_offer, if any, upon receiving this event.

We still buffer the entire clipboard data into memory because we have no
knowledge of the clipboard data size in advance and cannot do incremental
transfers.

Furthermore, if the user performs drag-and-drop on our window, we may have
need to handle multiple wl_data_offer objects at the same time. Therefore,
instead of storing state on the global wlCb object, we instead allocate
memory and store it as user_data on the wl_data_offer. As a result, we also
handle drag-and-drop so that we can free the memory.

75a9e38e3a [client] wayland: remove sync transfer for VM->host copies
Since we are using epoll, there is no longer any need to remove O_NONBLOCK
with fcntl, and the comment is also no longer relevant.

000d91afca [client] wayland: prefer PNG over other image types
Support for non-PNG types is optional in the spice agent, so we should
avoid sending those if PNG is available.

Currently, the spice VDAgent supports only PNG and BMP formats.

854b53e28c [client] wayland: use consistent naming in poll module
Some of the functions were named WaylandEpoll*, which is inconsistent.
This commit changed them to be WaylandPoll*.

798a1aadb5 [client] wayland: fail gracefully when interfaces are too old
Before, we just attempt to bind, causing an obscure Wayland error.
This commit checks the interface versions and print better error
messages.

5649d1ad95 [client] wayland: split Wayland display server into modules
The Wayland display server is getting unwieldy due to the sheer size.
To make it easier to edit in the future, I split it into many components
based on logical boundaries.
