emu/diimage.h: Removed fread overloads that allocate memory for output.
util/core_file.cpp: Changed output size of load to size_t.

- Add noexcept to format information overrides and several simple floppy_image accessors.
- Be more const-correct and use references instead of raw pointers wherever applicable. In particular, floppy_image_device::load and floppy_image_device::save now take a reference to floppy_image rather than a pointer, const-qualified in the latter case.

the simpler functions in multibyte.h
* multibyte.h: Add constexpr for getters and noexcept for all functions

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.
