The cache for files is initialized at the first read/write operation.
- Merged vfatExtendSpace and VfatSetAllocationSizeInformation in one function.

CcSetDirtyPinedData. There is no working shutdown function
for writing back each modified cache segment. A reboot or
crash can damage the disk.
- Added CcRosReferenceCache and CcRosDereferenceCache.
- Check at each call to CcRosInitializeFileCache if the cache was
initialized for the file stream by a previous call to this function.
- Check at each call to CcRosReleaseFileCache if this is possible
to delete the caching for the file stream.

or force the uninitialization if the last section of a file is deleted.

- EXT2/EXT3 file system support.
- Does not yet support symbolic links or booting from an EXT2/3 partition.
- Fixed bug in UI code.
- Added '%%' format specifier to printf()-like functions.
- Added functions __udivdi3 & __umoddi3 so that 64-bit division is now supported.
- Changed types BYTE, WORD, DWORD, LONG, ULONG to U8, U16, U32, S32, U32
so that you know the size of the variable across different
architectures with different sized words & dwords, etc.
- Types CHAR, UCHAR, PCHAR, PUCHAR, WCHAR, PWCHAR have not been
changed yet (I haven't decided exactly how I'm going to handle unicode)
(isn't this an awesome commit? ;-) Just look at that list of files)
