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

e5f86a824a [client] switch back to atomic locking as the default
The prior patch to correct the mouse loop resolves the CPU load issue
with the atomic locking method. SDL mutexes are still available if
desired but full mutex locking is far slower then fast spinlocks

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
