* formats, osd, util: Started refactoring file I/O stuff. (#8456) Vas Crabb2021-08-221-7/+14
| | | | | | | | | 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.

The UniFLEX disk format is not compatible with the Flex format. Significantly it does not use a mix of single density for booting on some double density disks which makes it simpler - hardware required a new boot ROM to run UniFLEX. Further, the UniFLEX sector size is 512 bytes versus 256 for Flex, and the UniFLEX 'SIR' info sector record is completely different to the info on Flex disk, and the file system format is also not at all compatible. Thus the UniFlex format can rely largely on the WD17xx format, with an overload to handle the sector numbering on the second side continuing from the first side (one feature in common with the Flex format). This gives a quick 'save' capability and shares code. Support for 8" disks is included as this was the initial distribution format and the only one found so far.
