2993f7ae7d [client] egl: create 24-bit colour context
This should prevent the looking-glass-client window from having an alpha
channel. On Wayland, the alpha channel is used to compose the window onto
the desktop, so the wallpaper would bleed through unless set to complete
opaque.

We worked around this by using constant alpha for rendering, but it was
not sustainable. Instead, we should just ask for 24-bit context.

5ac53362a3 [client] renderer/egl: implement support for rendering help text
The help text is rendered in the bottom left corner on a semi-transparent
background, very similar to how the FPS text is rendered.

8559b354ae [client] egl: always render desktop texture as opaque
We ask for 32-bit colour buffer when creating the EGL context. On Wayland,
this sometimes give contexts with alpha channels, resulting in unwanted
transparency. So we clear the alpha channel in the desktop shader.

We also switch to using constant alpha for blending the splash, which
avoids more alpha issues.

637a7625d2 [client] wayland: allow EGL/OpenGL vsync to be set to on
This effectively reverts 4bceaf5.

Upstream ticket: https://gitlab.freedesktop.org/mesa/mesa/-/issues/4180

Commit 941c651 makes working around the hang in LG itself not as
annoying as before.

In the future, we can bypass this entire issue by implementing our own
swapchain and listening to frame callbacks ourselves.

Build failed with _FORTIFY_SOURCE enabled because the compiler couldn't

a46a3a2668 [all] use explicit void parameter lists
This makes it a compile-time error to call a function that semantically
takes no parameters with a nonzero number of arguments.

Previously, such code would still compile, but risk blowing up the stack
if a compiler chose to use something other than caller-cleanup calling
conventions.

1ca5e439c1 [client] egl: disable EGL when running on Wayland
This commit makes Looking Glass always use the OpenGL renderer when
running on Wayland. The EGL renderer is broken on Wayland and can't
reasonably be fixed until SDL is dropped entirely (as per
https://github.com/gnif/LookingGlass/issues/306).

Until that time, the OpenGL renderer provides a much better
Wayland-native experience.

4bceaf5505 [client] fix hang in eglSwapBuffers when exiting while not visible
eglSwapBuffers is allowed to block when called with a nonzero interval
parameter. On Wayland, Mesa will block until a frame callback arrives.
If an application is not visible, a compositor is free to not schedule
frame callbacks (in order to save CPU time rendering something that is
entirely invisible).

Currently, starting Looking Glass from a terminal, hiding it
entirely, and sending ^C will cause Looking Glass to hang joining the
render thread until the window is made visible again.

Calling eglDestroySurface is insufficient to unblock eglSwapBuffers, as
it attempts to grab the same underlying mutex.

Instead, this commit makes it so that we pass a 0 interval to
eglSwapBuffers when running on Wayland, such that we don't block waiting
for a frame callback. This is not entirely ideal as it *does* mean
Looking Glass submits buffers while hidden, but it seems better than
hanging on exit.

It also forces opengl:vsync and egl:vsync flags to off when running on
Wayland, as they are meaningless there.

Recent versions of Mesa may have trouble with surface creation, resulting in
errors like:
egl.c:428  | egl_render_startup             | Failed to create EGL surface (eglError: 0x300b)

[How]
Replace eglGetDisplay() with eglGetPlatformDisplay(). Requires EGL 1.5, but should
be supported with any desktop driver released in the past few years.

bca54ab1f6 [client/host] added new asyncronous memory copy
This changes the method of the memory copy from the host application to
the guest. Instead of performing a full copy from the capture device
into shared memory, and then flagging the new frame, we instead set a
write pointer, flag the client that there is a new frame and then copy
in chunks of 1024 bytes until the entire frame is copied. The client
upon seeing the new frame flag begins to poll at high frequency the
write pointer and upon each update copies as much as it can into the
texture.

This should improve latency but also slightly increase CPU usage on the
client due to the high frequency polling.
