5ad70ccc41 [common] crash/linux: generate core dump when handling SIGSEGV 
Calling abort() instead of exit() will generate a core dump, allowing gdb
to be used when the client crashes. This is desirable for the following
reasons:

1. gdb can be used to inspect the call stack with far more detail than the
   our quick stack trace code, and also allows the access to the heap.
2. Our SIGSEGV handler is unable to use debug symbols for shared libraries,
   making it impossible to debug bugs involving drivers and similar.

6358f35cb7 [common] detect clang and disable warnings for unknown-warning-option 
Clang doesn't know the warning option `format-truncation`, which GCC
falsely triggers on when calling vsnprintf. Further to this, GCC doesn't
understand the warning group `unknown-warning-option`, as such we must
disable these warnings in the cmake.

5649d1ad95 [client] wayland: split Wayland display server into modules 
The Wayland display server is getting unwieldy due to the sheer size.
To make it easier to edit in the future, I split it into many components
based on logical boundaries.

db16efe68b [common] add a reference counted buffer type 
This allows buffers to be shared between different asynchronous operations.
Once all users no longer need the buffer, it will be freed.

The motivation for this is being able to stream Wayland clipboard data
asynchronously to multiple clients. The buffer should only be freed after
the clipboard has changed and all ongoing transfer completes.

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.

e31f38eadc [client] allow frame updates to be triggered by a timed event

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.
