-si/-so for fazip mode, datafiles, and outarchive and Virtual Lua I/O

[Bulat-Ziganshin]

Ideally, it should be implemented via Virtual Lua I/O, that supports the following operations:

• OpenInputArchive, OpenOutputArchive, OpenFileToCompress, OpenFileToExtract, OpenFile (this allows to check prior to operation which operations were virtualized and skip going through the Lua side on operations that were not virtualized)
• Seek, Size, Read, Write, Close operating on LuaRef handle returned by Open operations
