d591e2fd36 [client] added xlib-shim to disable calls to XSync 
The compiled xlib-shim.so can be used to intercept and prevent SDL
from calling XSync, which causes latency issues on some video
hardware.

To use specify the full path to the file in the LD_PRELOAD
environment variable, like so:

LD_PRELOAD=/full/path/xlib-shim.so ./looking-glass

c61d97b0ac [client] spice: add channel and mouse locking 
This fixes a race condition which causes the mouse ringbuffer to
overflow. It also corrects out of order message index IDs due to
multiple threads sending messages asyncronously.

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

c38e38d43d [client] opengl: add splitmouse option 
This feature was previously hardcoded enabled, it is now optional as
some hardware pipelines stall with the excessive flushes resulting in a
jumpy cursor. Default is disabled and may be re-enabled with
`-o opengl:splitmouse=1` or `-o opengl-basic:splitmouse=1` depending on
the renderer selected.

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.

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

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.
