SCI file handling rewrite
|Reported by:||fingolfin||Owned by:|
The attached patch is a first attempt at rewriting file handling code in the SCI engine to use the portable file (& savefile) APIs provided by ScummVM, instead of POSIX file handling APIs.
It is not well-tested nor complete; there are numerous comments explaining caveats and limitations throughout the patch.
