4f9544d61d [client] egl: added DMA texture support for direct upload
Note: This only works with the KVMFR kernel module in a VM->VM
configuration. If this causes issues it can be disabled with the new
option `app:allowDMA`

ede96fa486 [client] egl: don't map the texture until it's needed
The texture buffer may still be in use if we try to re-map it
immediately, instead only map when we need it mapped, and unmap
immediately after advancing the offset allowing the render thread to
continue while the unmap operation occurs

e31f38eadc [client] allow frame updates to be triggered by a timed event
This is a major change to how the LG client performs it's updates. In
the past LG would operate a fixed FPS regardless of incoming update
speed and/or frequency. This change allows LG to dynamically increase
it's FPS in order to better sync with the guest as it's rate changes.

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.

fc66a4a19c [client] egl: use persistant mapped texture buffers
While it is recommended to use memory barriers when updating a buffer
like we are, since we double buffer it is unlikely we will corrupt a
prior frame, and even if we do since it's just texture data at worst
we might see a tear.
