70110b4a5a [client] Use eglGetPlatformDisplay() to fix surface creation
[Why]
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.

fc66a4a19c [client] egl: use persistant mapped texture buffers
While it is recommended to use memory barriers when updating a buffer
like we are, since we double buffer it is unlikely we will corrupt a
prior frame, and even if we do since it's just texture data at worst
we might see a tear.

695822bd6d [client] redesign of the renderer archiceture for mt support
This is the first of two commits that completely turn the rendering code
on it's head. This change set decouples the guest's capture rate from
the host's render rate for both cursor and frame updates. This helps
prevent the host application from stalling when waiting for frame draws
when all it want's to do is send cursor updates.

* Breaks OpenGL-Basic for now

the renderer selected.

This adds back in double buffering and vsync support. This has been
