Xpra: Ticket #491: webp is leaking memory

See ticket:457#comment:30 - this is a client side leak only (I think), which affects all platforms.

Probably keeping references to some buffers somewhere (create_string_buffer?)

Fix it so we can actually use webp (and fix #487), and use it for more things. (ie: #419)

r5167 adds a big warning for anyone trying to use webp, will need to be removed if/when we figure this out
