62b27760ea [common] ivshmem: do not create dmabuf for simple mmap 
It used to be the case that you need to create dmabuf for kvmfr devices
to be able to mmap them. But after #457, this is no longer needed.

Directly mmaping the kvmfr device has the advantage of avoiding the
creation of a dmabuf, which has cost (e.g. the list of pages, the
scatterlist, etc.).

8e98f863b6 [host] windows: detect whether screensaver is disabled in the guest 
This will allow us to add an option to disable the screensaver on the client
when an application in the guest requests it. This behaviour may be useful
when the guest is doing media playback.

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.

7e362050f7 [all] update KVMFR to provide cursor hotspot information 
This commit bumps the KVMFR protocol version as it adds additional
hotspot x & y fields to the KVMFRCursor struct. This corrects the issue
of invalid alignment of the local mouse when the shape has an offset
such as the 'I' beam.

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.
