Michael Chisholm 2cc2cc2e39 Moved disc interfaces to appropriate libraries (DLDI to libnds, SD/USB to libogc).
Changed read/write functions to use size_t and seek function to use off_t -- will help on 64 bit platforms.
Partitions no longer specified by fat1:/, fat2:/, etc.
Use "nice" device names. On GBA/NDS the default partition is still fat:/; however on Wii and GC sd:/, usb:/, etc. are used instead.
Added fsync and ftruncate functions.
Mount and unmount no longer startup/shutdown the device, this is the job of the host app.
Mount now accepts a partition start parameter.
Used standard types, eg uint32_t instead of u32.
Archive bit is set when closing/synchronizing a modified file.
Various minor bug fixes.
