dwrite: Added stub EUDC font collection.
usp10: Correct an off-by-one error in page cache allocation.
winemac: Ignore Cocoa child windows which aren't instances of WineWindow.

On Yosemite, in full-screen mode, Cocoa adds child windows of its own to our
windows.  These windows are, of course, not instances of WineWindow.  So, when
we call WineWindow-specific methods on them, it throws exceptions.
mmdevapi: More accurately track device position.
wineoss.drv: Don't use SNDCTL_DSP_GETISPACE.

This shouldn't be needed as the device is opened in non-blocking mode,
and it appears this function is unimplemented on PCBSD.
winspool.drv: Don't crash if the ppd directory cannot be created.
winemenubuilder: Prevent recursion by calling open_module_icon() instead of open_icon()
quartz: Implement IFilterGraph2::AddSourceFilterForMoniker.
ntdll: Unify retrieving the attributes of a file.
