- add timeout when calling XCheckTypedWindowEvent
- fix broken IsClipboardFormatAvailable; it tried to do a trick with
EnumClipboardFormats by making incorrect assumptions
- in X11DRV_IsClipboardFormatAvailable do a quick exit if no one owns
the selection
- add 1 second *minimum* time lapse between XSelectionOwner calls
- sync clipboard ownership between different wine processes
- prevents apps from getting into wierd state where they thought they
didn't own the selection but they did and as a result queried
themselves for available selection data
- Add new function to the x11drv to get clipboard format names of
externally registered formats.
- When a clipboard format is registered we should pass the global atom
value as the format identifier.
- Clipboard format name should be treated as case insensitive.
- Serialize metafile bits when requested via a clipboard selection.
- Return format ids for native formats when mapping from properties.
