cc2c49644d [spice] reworked to avoid locking requirements on the input channel 
POSIX `send` is thread safe, to take advantage of this the code has been
changed to construct a contiguous buffer and perform the send in a
single operation preventing any risk of a race condition.

Only the main channel still requires an interlock as the VD agent
requires multiple sends to transmit a full buffer.

406e22a681 [client] override new behaviour in SDL 2.0.15 and disable xinput2 
xinput2 is used to get touch interface events with the side effect of
consuming MotionNotify events which we use because of SDL2's inability
to correctly track the window size. Since we are not that intertested in
touch for our usecase, we just turn the events off again.

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.

21b02efb4d [c-host] dxgi: don't stall the GPU pipeline to map textures to ram 
ID3D11DeviceContext_Map by default will force a CPU sync if the prior call to
CopyResource has not completed, this change defers the mapping and sets the
D3D11_MAP_FLAG_DO_NOT_WAIT when attempting to map the texture allowing the
capture to continue without incurring an expensive CPU/GPU sync.

A new tuneable has also been added
