0ac1992019 [client] add new OpenGL-Basic renderer 
This is based on bf8da7fd7e4397fe9931e82e52753806f1eee7e0 by @kiljacken
Per issue #11 on some cards this method performs much better then the
persistant buffering used in the standard OpenGL renderer.

Closes #11

06e38d897d [client] implemented renderer specific option API 
Please note the vsync and mipmap options are now specific to OpenGL
To configure them use the following options:

  -o opengl:mipmap=1
  -o opengl:vsync=0

fe337cf510 [client] ivshmem: fix missing <sys/select.h> include 
While the function `ivshmem_wait_irq` makes use of the select(3)
function, it does not include <sys/select.h>. This happens to work on
glibc based systems, which include thet file transitively via other
header files. But on musl libc based systems, this breaks compilation.

Directly include <sys/select.h> to fix the problem.

9c03327701 [client] opengl: added back double buffering and vsync support 
This adds back in double buffering and vsync support. This has been
carefully implemented so that the render function blocks until the video
card reports that it has advanced a frame, this ensures that the OpenGL
pipeline never buffers frames.

7349334811 [client] reworked polling logic and added GPU magic 
SDL_RenderPresent calls SwapBuffers which doesn't block even with vsync
enabled until the driver/gpu has buffered several frames, this is no good
for our use case where low latency is of ultimate importance. This patch
measures the swap interval, ensures the time is consumed and then calls
glFinish to ensure that there is no buffered data. The results on NVidia
hardware are exceptional, but will need verification on AMD hardware.

Polling logic has also been improved, the client will hunt for the best
delay rather then resorting to waiting on an event from the guest, avoiding
scheduler latency caused by waiting on the irq event.
