formats, osd, util: Started refactoring file I/O stuff. (#8456)
Added more modern generic I/O interfaces with implementation backed by stdio, osd_file and core_file, replacing io_generic. Also replaced core_file's build-in zlib compression with a filter. unzip.cpp, un7z.cpp: Added option to supply abstract I/O interface rather than filename. Converted osd_file, core_file, archive_file, chd_file and device_image_interface to use std::error_condition rather than their own error enums. Allow mounting TI-99 RPK from inside archives.
