Remove LegacyDefaultOptionalArguments flag from DOM-related files except Document.idl

[Mark Pilgrim (Google)]

As discussed in IRC, we are migrating our IDL files away from the interface-level "LegacyDefaultOptionalArguments" flag and onto argument-level [Optional] or [Optional=CallWithDefaultValue] flags. This patch migrates all remaining IDL files in the dom/ directory *except* Document.idl. It does not change any behavior, i.e. it does not make any arguments required that were previously optional, nor vice-versa.

All existing tests pass.

is RequiresAllArguments still needed for setData ?

I'm slightly unsure about this one.  The MediaStream stuff is very new, so maybe it doesn't need it?  On the other hand, having all these fake vectors be consistent seems beneficial.

This probably isn't needed.

Same thing here.  TOUCH_EVENTS are very new.  I think we should skip these even though it's somewhat inconsistent.

Yes. [RequiresAllArguments] is different from [RequiresAllArguments=Raise].

Because it returns undefined?  It might be good to test other browsers to see if we're really not supposed to Raise in this situation.

This patch changes the behavior of MediaStreamList and MediaTrackList, but it doesn't change Clipboard.
