We were unnecessarily looping/goto-ing repeatedly when we had exactly
the amount of data as the free space, and also when the free space was
too small. This, as it turns out, is a very common scenario with
Directsound on Windows.
Fixes https://bugzilla.gnome.org/show_bug.cgi?id=773681
We have to do polling here because the event notification API that
Directsound exposes cannot be used with live playback since all events
must be registered in advance with the capture buffer, you cannot
add/remove them once playback has begun. Directsoundsrc had the same
problem.

D3DX has been deprecated for the last 4 years and latest versions of
Windows no longer ship headers for it. This is fine as long as you're
building with Cerbero's Wine-based DirectX headers, but sucks if you
want to build against the actual Windows SDK.
We were just using it to get error strings anyway, so just use the
generic error string API.
If GetStatus() fails, the status itself won't be very meaningful but we also
have to look at its return value. This fixes blocking pipelines when removing
sound devices or during other errors, where we wouldn't notice the error and
then wait forever.

Pretending to handle 8-bit signed causes distorted audio when
actually given such audio, which you will get if passing 8-bit
unsigned through audioconvert ! audioresample, as audioresample
only handles 8-bit signed. Fixes#605834.
