In the writev() tests, the handling of cancellation is tested. However,
the GCancellable was cancelled after the writev_async() call was
started. Depending on the implementation of the writev() vfunc, the
operation could be done in a thread or in callbacks on the current
thread’s main loop. If done in a separate thread, there’s a chance that
enough of the write could happen before cancellation reaches that thread
that the overall operation returns success with a short write.
That would cause the test to fail, sometimes.
Avoid that by cancelling the GCancellable before starting the writev()
operation.

This is an analogous commit to c1f5e528. The original fix only touched
gtype.h and not gtypemodule.h.
The *_init() functions have prototypes incompatible with *InitFunc types they
are being cast to. This upsets GCC 8's -Wcast-function-type that's enabled by
default with -Wextra.
Let's not have the public header files emit a warning and neutralize it by
doing a void(*)(void) cast first.

We must use the platform specific method to create an IO channel
out of an fd. The test still does not work on Windows but
this is a step forward in the direction to make it work.
It would always be initialized but initialize it to NULL to silence the
compiler, and also check that it is not NULL anymore when we expect it
to contain a valid value.

It could've never been uninitialized in this code but the code flow is
not obvious to the compiler. Initialize it to NULL and for clarity also
add an assertion that it is not NULL anymore on usage.

This allows returning WOULD_BLOCK without allocating a GError, and
should later be used for various functions of GPollableOutputStream,
GPollableInputStream and anything else that can potentially block.
