5f5f497cbd [host/common] windows: provide delayExecution via nsleep
This change moves this platform specific sleep to `common` as the OS
agnostic `nsleep` function.

f5dfc264ba [host] windows: trick MinGW into not using memcpy from ntdll
MinGW seems to decide at random whether it wants to use memcpy from
mscvrt.dll or ntdll.dll. Currently, on Debian buster, ntdll.dll is chosen,
while on sid, mscvrt.dll is chosen.

This commit declares a new .def file for ntdll containing only the
functions we want to link from ntdll.dll, and generates ntdll.a from it
with dlltool. This way, MinGW will never be tempted to link functions
like memcpy from ntdll.dll.

88fc1a6d24 [host] windows: directly invoke ChangeWindowMessageFilterEx
This requires bumping the minimum Windows version to Windows 7, but I
don't think we care about Vista anyways.

28a67cad0d [host] windows: avoid compiling .rc file twice
a4f5ce08b9 has a regression that caused
the .rc file to be compiled twice. We do not want the version that's
added into the .a file.

323d321a77 [host] windows: correctly declare WINVER and _WIN32_WINNT
We wanted to target Windows Vista, which is 0x0600 not 0x6000.
0x6000 is in fact larger than Windows 10 which is 0x0a00.

56833edae7 [host] delay: directly link against ntdll.dll
There is no need to LoadLibrary and GetProcAddress to get pointers to
NtDelayExecution or NtSetTimerResolution. These functions don't have
prototypes in any SDK header, but they are exported in ntdll.dll and
we can simply declare the prototype and link ntdll.

There is also no chance that the functions do not exist: I checked an
old install of Windows NT 4.0 and both of these functions exist.

Also used NtSetTimerResolution instead of ZeSetTimerResolution for
consistency (they are the same).

Also changed system timer resolution log message units to μs with
one decimal digit for readability. This is the actual amount of
precision available to us.

16ee1a825c [host] windows: use event to gracefully signal exit
This allows the process to be terminated without resorting to
TerminateProcess. With some fixes, this allows the notification icon to be
removed when the service is restarted.

Furthermore, instead of sending WM_DESTROY to fool the window into believing
it's being destroyed, we actually call DestroyWindow now.

411a6b1e49 [host] windows: add delayExecution function for more accurate sleeps
This change not only exposes and allows use of NtDelayExecution, but
also moves the code to set the system timer resolution.

cd10e02862 Revert "[host] avoid manual windres command"
This reverts commit d82f2e510d.
While the proposed change is more correct, it breaks the generation of
the file due to failure to locate the resource files, such as
`resources/icon.ico`.

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.

1761ea2b9b [host] windows: move log path to %ProgramData%\Looking Glass (host)
Instead of using %windir%\Temp, which is not accessible by default and
contains a lot of unrelated files, as the location for our log files,
this commit moves it to %ProgramData%\Looking Glass (host), which will
be a dedicated directory just for the LG host log files. This applies
to both the host application logs and the service logs.

Also, we now switched to using PathCombineA from shlwapi.dll instead
of using snprintf, which greatly simplifies the code. PathCombineA
guarantees that the path would not overflow a buffer of MAX_PATH.

ffa72c7992 [host] nvfbc: force composition to capture some full screen apps
NvFBC is unable to capture certain applications that bypasses the DWM
compositor, for example, Firefox playing video in full screen. This
has been a known issue for a long time with Nvidia's ShadowPlay, see:
* https://www.nvidia.com/en-us/geforce/forums/geforce-experience/14/233709/
* https://crbug.com/609857

Nvidia won't fix this, but there are workarounds. For example, we
create a transparent 1x1 layered window, which forces desktop composition
to be enabled.

Note that SetLayeredWindowAttributes also supports alpha-based transparency,
but setting transparency to 0 will cause DWM to skip composition. We could
use a transparency of 1, but this ruins the image by the slightest bit,
which is unacceptable. Therefore, we must use chroma key-based
transparency, which tricks DWM into compositing despite being fully
transparent.

323aab8ec2 [host] windows: improve restart logic and remove mutex hack
Use the process handle returned by CreateProcessAsUserA to wait on the
process. This results in faster response times and less polling.
For example, it now restarts instantly when UAC is activated.

This also removes the call to OpenProcess and rendering the mutex unnecessary.

As a bonus, it should fix #298.

9a6b598438 [host] Windows: Implemented service to launch LG as the SYSTEM user
Experimental, use at your own peril!

This commit adds the ability for the LG host to install and launch with
Windows as a system service.

To install simply run `looking-glass-host.exe InstallService` or
conversely to uninstall `looking-glass-host.exe UninstallService`.
