37ea662998 [client] use SDL_SetEventFilter for better mouse performance
This partially resolves lag issues on hosts running the amdgpu driver.
If mouse caputure is enable the lag issue returns, this is because SDL
calls `XSync` in `X11_WarpMouse` and `X11_WarpMouseGlobal`, if these
calls are removed all input lag issues dissapear.

This issue has been reported to SDL as the calls to `XSync` are not
required per the xlib documentation.

40bfdcdf8c [client] added configuration file loading support
the client now will look for a configuration file in the following
locations by default.

* /etc/looking-glass.conf
* ~/.looking-glass.conf

All configuration files are loaded and may override values specified by
any prior configuration files loaded.

Sample Config:

    global:
    {
      fullScreen=false;
      showFPS=true;
      x=0;
      y=0;
      w=800;
      h=600;
    }

    OpenGL:
    {
      mipmap="false";
    }

6a6e53f728 [client] removed the dependency on the ivshmem-server
Since we do not use IRQs anymore we can use the ivshmem-plain device
which doesn't need the ivshmem-server. The QEMU arguments now should be
as follows:

-device ivshmem-plain,memdev=ivshmem
-object memory-backend-file,id=ivshmem,share=on,mem-path=/dev/shm/looking-glass,size=32M

Obviously adjusting the memory size as required. It is suggested that
the shared memory file be created before the guest is started with the
appropriate permissions, for example:

touch /dev/shm/looking-glass
chown user:kvm /dev/shm/looking-glass
chmod 660 /dev/shm/looking-glass

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

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.
