Fix concurrency bugs in FAT_getAttr/FAT_setAttr. ( #13 )
...
A relatively rare concurrency bug existed in these methods due to them not
correctly holding the partition lock during calls to
_FAT_directory_entryFromPath. That method can trigger reads to the partition.
Due to the lock not being held, another thread could still trigger a concurrent
read, potentially corrupting the cache. The fix is simply to ensure the lock is
held around the calls.

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.
