This function enumerates all user-accessible UWP packages
and calls the user-provided callback for each package.
This can be used to make GLib aware of the UWP applications
installed in the system.
The function works by using IPackageManager/IPackage UWP interfaces
and XmlLite COM library to parse package manifests.
The function requires COM, and initializes it to a single-thread
appartment model. To ensure this doesn't break anything, either
only use it in a separate thread (COM is initialized on a per-thread
basis), or make sure that the main thread also uses the same COM
model (it's OK to initialize COM multiple times, as long as the same
model is used and as long as init/uninit calls are paired correctly).
MinGW-w64 lacks the appropriate headers, so we have to add them
here. Note that these only have the C versions (normally these
things come in both C and C++ flavours), since that's what we use.
Also note that some of the functions that we don't use (but must
describe to maintain binary compatibility) were altered to use
IUnknown (basically, an untyped pointer) instead of the appropriate
object types, as adding these types would require other types,
which would pull even more types, forcing us to drag half of the
UWP headers in here. By replacing unused types with IUnknown we
can trim a lot of branches from the dependency graph.
This is a COM object that implements IStream by using a HANDLE
and WinAPI file functions to access the file (only a file; pipes
are not supported). Only supports synchronous access (this is
a feature - the APIs that read from this stream internally will
never return the COM equivalent of EWOULDBLOCK, which greatly
simplifies their use).
Just embed a PNG instead. gdk-pixbuf deprecated its pixdata support in
version 2.32, in 2015.

Fixes: #1281
Also adds a test that checks that the G_SIGNAL_RUN flags are handled
correctly and the class signal handler is called at the right times.

Realistically any date over 200 bytes long is not going to be valid, so
limit the input length so we can’t spend too long doing UTF-8 validation
or normalisation.
