7e15ec5e66 [common] windows: implement crash handler for stack traces 
This commit uses the DbgHelp library which is shipped with Windows to
generate stack traces with function names and line number information.
It takes advantage of the pdb file generated by cv2pdb that is now
installed with looking-glass-host.exe.

afa277f8ee [common] ivshmem/linux: add stubs for ivshmemInit and ivshmemFree 
These two functions were added in 9ff1859dc1
for Windows, but were never used on Linux.

Adding stubs will allow the host to compile on Linux.
These should be fixed later.

a46a3a2668 [all] use explicit void parameter lists 
This makes it a compile-time error to call a function that semantically
takes no parameters with a nonzero number of arguments.

Previously, such code would still compile, but risk blowing up the stack
if a compiler chose to use something other than caller-cleanup calling
conventions.

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.
