Now LG uses a 25Hz tick timer it is an issue that `create_timer` spawns
a new thread for every single timer event, so instead multiplex all the
timers into a single thread with a 1ms resolution.
Sometimes, e.g. when xdg-open has to start the browser, the xdg-open
process can stay around until the browser exits, which freezes the
client. Instead, we should not wait for xdg-open to exit.
However, we can't simply not call wait, as that would leave the
xdg-open process around as a zombie. We could turn off the SIGCHLD
handler, but that's a global solution to a local problem. Instead, we
call setsid and fork again to detach the xdg-open process as if it's a
daemon, and let init take care of the reaping process.

The old code will not correctly report the number of threads on CPUs with
more than one processor group, i.e. when there are more than 64 logical
processors (threads).
The signature for calloc is void *calloc(size_t num, size_t size), where num
is the number of elements to allocate, and size is the size. Therefore, to
allocate a single struct, we should pass 1 for num and the size of the struct
as size.
In some places, we use the opposite order, and we should flip it.
Before, if the size is exactly the multiple of the page size, an extra padding
page is added for no reason. This commit fixes the logic and also uses the
page size obtained dynamically.
This is currently only implemented for Linux.
On Windows, ShellExecute should be used, but that should be done when it's
actually needed so it could be tested.
We now enumerate all IVSHMEM devices, sort them based on PCI bus, slot,
and function numbers, then index from the resulting order. This should
be consistent across boots.
To help the user identify the correct IVSHMEM device, we also print the
list of IVSHMEM devices on startup.
When our window is destroyed, our timers are also destroyed. This causes our
attempt at destruction to fail. Instead, set MessageHWND to NULL in the
WM_DESTROY handler and don't try destroying the timers if the window is gone.
