5fe529f213 [client] spice: allow volume control keys to be sent to the guest 
These are implemented as ScrollLock+Up/Down for volume up and down, and
ScrollLock+M to toggle audio mute. These should prove useful especially
when Looking Glass now supports streaming audio, and the volume is
defined in the guest and set on the output stream.

7c91c922e6 [client] input: avoid reentrancy when realigning guest cursor 
This prevents LGMP_ERR_QUEUE_FULL from happening with high polling rate
mice, which is caused by receiving many more mouse events while the
guest cursor warps, triggering more warps.

f635077a2c [client] egl: increase texture processing timeout 
On my machine (Intel UHD Graphics 770), texture processing occasionally
(about 5% of the time) takes more than 20ms (the highest I have seen is
around 32ms) when the host resolution is 2560x1440. This results in the
frame being discarded and the client displays a stale image. Increase the
timeout to 40ms.

Chris Spencer
ef9b2958ec [client] audio/pw: set maximum node latency 
This prevents severe buffer underruns if the PipeWire quantum is bigger
than the ring buffer size. This could happen if a media player is running
at the same time as Looking Glass if it requests a very large quantum size,
for example.

4c389a9274 [client] audio/pw: flush playback buffers before stopping 
This stops the end of the playback from being truncated. It also prevents
an audible glitch when playback next starts due to the truncated data being
left behind in the ring buffer.

35334333ac [client] imgui: render twice for alerts 
When using jitRender, or on the first frame of an alert the window
doesn't get resized immediately causing it to cut off the end of the
text.

ImGui needs two passes to calulate the bounding box for automatically
sized windows, this is per it's design and not a bug, see:

ba9f2b85b6 [host/client] kvmfr: update to include extra user data about the VM 
This change allows the host to provide information to the client about
how the VM is configured, information such as the UUID, CPU
configuration and capture method both for informational display in the
client as well as debugging in the client's logs.

The format of the records allows this to be extended later with new
record types without needing to bump the KVMFR version.

This commit eliminates the race by performing the update when

12840a8324 [client] x11: load glXSwapIntervalEXT dynamically 
The Linux OpenGL ABI does not guarantee that glXSwapIntervalEXT will be
exported statically from any library, and indeed on some systems this
function does not link at load time, e.g. with amdgpu-pro. All other
GLX functions that we use are from GLX 1.0, which is guaranteed to be
exported statically.

This commit solves this issue by using glXGetProcAddressARB to load the
function. Note that only the ARB version of glXGetProcAddress is
guaranteed to exist by the Linux OpenGL ABI, which is why we must use
it.
