The custom action uses cmd.exe to run VSS Service installation
and removal which causes an interactive command shell to spawn.
This shell can be used to execute any commands as a SYSTEM user.
Even if call qemu-ga.exe directly the interactive command shell
will be spawned as qemu-ga.exe is a console application and used
by users from the console as well as a service.

As VSS Service runs from DLL which contains the installer and
uninstaller code, it can be run directly by rundll32.exe without
any interactive command shell.

Add specific entry points for rundll which is just a wrapper
for COMRegister/COMUnregister functions with proper arguments.

Remove the 'change' button from "Programs and Features" because it does
not checks if a user is an admin or not. The installer has no components
to choose from and always installs everything. So the 'change' button is
not obviously needed but can create a security issue.

According to GLib changelog [1], since version 2.73.2 GLib is using
libpcre2 instead of libpcre.  As a result, qemu-ga MSI installation
fails due to missing DLL when linked with the newer GLib.

This commit makes wixl to put the right libpcre version into the MSI
bundle: either libpcre-1.dll or libpcre2-8-0.dll, depending on the
present version of GLib.

This commit allows QGA to write to Windows event log using Win32 API's
ReportEvent() [1], much like syslog() under *nix guests.

In order to generate log message definitions we use a very basic message
text file [2], so that every QGA's message gets ID 1.  The tools
"windmc" and "windres" respectively are used to generate ".rc" file and
COFF object file, and then the COFF file is linked into qemu-ga.exe.

libstdc++ is required for the qga-vss.dll that provides fsfreeze
functionality. Currently it is not provided by the MSI installer,
resulting in fsfreeze being disabled in guest environments where it has
not been installed by other means.

In the future this would be better handled via gcc-cpp ComponentGroup
provided by msitools, but that would be better handled with a general
rework of DLL dependency handling in the installer build. Keep it
simple for now to fix this regression.

Tested with Fedora 34 mingw build environment.

It's nicer from a management perspective that the agent can survive
hotplug/unplug of the channel device, or be started prior to the
installation of the channel device's driver without and still be able
to resume normal function afterward. On linux there are alternatives
like systemd to support this, but on w32 --retry-path is the only
option so it makes sense to set it by default when installed as a
w32 service.

Issue: When upgrading qemu-ga using the msi from an old version
       to a newer one, the upgrade is not allowed by the msi
       showing this error message "Another version of this product
       is already installed."

BZ# 1536331: https://bugzilla.redhat.com/show_bug.cgi?id=1536331

Fix: For the upgrade to be allowed by the msi the WiX file must
     provide three things:
      1. Changing product's Id. (assigning it to "*")
      2. Constant product's UpgradeId. (exists)
      3. Changing version. (exists)

mingw-glib uses helper process to assist gspawn() api. There are two
versions of helpers, one with main() and another with WinMain() startup
routines.

Whenever gspawn() detects consoleless environment (and qemu-ga is running
in such environment as Win32 service), it chooses helper with main()
instead of WinMain. It is done by name, e.g.
gspawn-win32-helper-console.exe vs gspawn-win32-helper.exe

Running console-aware application like any win32 console apps from main()
crt initalized process results in redirection of stdout to console created
in crt startup instead of parent-provided handle connected to subprocess
pipe. Thus, stdout/stderr redirection do not work correctly.

The patch makes WinMain()'s version of helper be used as the only helper
shipped with qemu-ga package. Using only win32 helper ensures console
is created before any redirection and fixes stdout/stderr redirection
issue.

Previously, running the .msi would unregister the QEMU GA VSS service if QEMU GA was already installed on the machine, and then register it only if QEMU GA was NOT previously installed. This behavior caused the service to be registered only after the INITIAL installation, and any subsequent run of the .msi (to redo, repair, or upgrade the installation) ended in the service being unregistered.

Now, the VSS service is still unregistered if QEMU GA is already installed (so that a fix or an update could be performed) but then it is registered again (if the GA is not being uninstalled) thus finishing the repair/upgrade correctly. Additionally, downgrading is now prevented. If a user would like to downgrade a version, he/she must uninstall the newer version first.
