[PATCH v4 1/1] winegstreamer: Implement Wow64 entrypoints in the Unix library.

[Kurt Kartaltepe]

From: Kurt Kartaltepe

This also converts the opaque pointers passed across the PE->Unix interface to opaque types
represented as UINT64 which store the unix side pointer. This makes the thunking simpler and should
avoid anyone accidently dereferencing the unix pointer in the PE code.
