[client] render/opengl: remove braces so fallthrough comment is recognized
...
gcc -Wimplicit-fallthrough only detects comments if they are immediately
preceded before the next label. Braces stops it from recognizing the
fallthrough comment.

[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.

[client] egl: detect the NVIDIA driver and disable DMA support
...
DMA suport for NVIDIA is advertised as available by the presense of the
extension `EGL_EXT_image_dma_buf_import`, however it is completely
broken. Until this is fixed refuse to use DMA support even if VM->VM
support is possible.

[client] require 8 bit colour when creating OpenGL context
...
For some reason, if we don't ask for 8-bit, wayland will give a context with
lower bit depth, which looks terrible.

[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.

[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.

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

[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.
