This MR introduces the driver mechanisms to handle dynamic events from the Wayland compositor, using wl_output events as the guiding use case (i.e., we want to update the win32u display settings when the host settings change).
In this design we create a dedicated thread to read and dispatch Wayland events received from the compositor. If a Wayland event handler wants some code to be run in the context of a particular HWND's thread, it can add an internal event to a custom queue we have for each (GUI enabled) thread. The ProcessEvents driver callback processes internal events from that queue. In order to wake up waiting threads we use a pipe to notify about new internal events, with the read end acting as the thread's host queue fd. This is similar to how winemac.drv works.
We use the aforementioned mechanisms to queue win32u display device updates to the desktop window thread. Since there are many pieces that need to fall into place, this MR gradually reaches the final design:
1. We first introduce the dedicated read/dispatch thread and handle events (and also display device updates if in the desktop process) in that thread. 2. We ensure access to Wayland output information is thread-safe and consistent (since in step 3 we will need to access it from a different thread). 3. We finally introduce per-thread internal event queues and, if we are in the desktop process, queue the display device update to the desktop window thread internal event queue. Note that the main portion of the wl_output event code is still handled in the dedicated read/dispatch thread.
-- v2: winewayland.drv: Update desktop window size on display changes. winewayland.drv: Do not process nested events. winewayland.drv: Update display devices from the desktop window thread. winewayland.drv: Introduce per-thread data. winewayland.drv: Make access to Wayland output information thread-safe. winewayland.drv: Handle dynamic Wayland output events. winewayland.drv: Read and dispatch Wayland events. winewayland.drv: Allocate process_wayland statically.

There is currently no benefit to dynamic allocation, and static allocation allows us to simplify some aspects of initialization. --- dlls/winewayland.drv/display.c | 2 +- dlls/winewayland.drv/wayland.c | 41 ++++++++++++--------------- dlls/winewayland.drv/wayland_output.c | 8 +++--- dlls/winewayland.drv/waylanddrv.h | 4 +-- 4 files changed, 25 insertions(+), 30 deletions(-)

Done (this was meant to be static all along, no plans to be used elsewhere at the moment).

You probably should print an `ERR` message.
Done.

Done. My rationale for being explicit about the type is that the default type (PTHREAD_MUTEX_DEFAULT) is not well specified in POSIX (in theory it could be mapped to any of the other mutex types), and I wanted to ensure we get the `normal` variant. On Linux it is indeed mapped to the `normal` type, but I am not familiar with the various BSD flavors, so I erred on the side of being more explicit. In any case, if the defaults are good enough for the rest of the code, they are good enough for winewayland.drv :)

Fwiw you don't need to sign-off your patches anymore. I'm also not sure why `process_wayland` is dynamically allocated? If it's going to be the only `struct wayland` instance, maybe having it static would make a few things simpler, like for instance its mutex initialization.
Removed sign-offs from patches.
I changed process_wayland to be statically allocated in a new (now first) commit in the series. I also took this opportunity to merge into `struct wayland` other Wayland-relevant global variables (`process_wl_display` and `process_wayland_initialized`).
Thanks!
