Fix two TStream issues: 1) It's not abstract anymore. Don't know since when exactly but at least in Sidney it's not abstract. 2) Read/Write(Buffer) prototype is bad and very impractical on Unicode. Make it like it really is: they accept a var of any type and this can be done in PS by using 'const' as the type and still _not_ using 'var'. Tested it to work unchanged when a string type is used in the call anyway. Also note this fix has no runtime changes so it's not surprising that it still works.
