Implement FsRtlAllocateResource, FsRtlIsPagingFile, FsRtlBalanceReads. Fix some incorrect function prototypes, rename mdl.c to fastio.c and add some more functions to it. Implement FsRtlGetfileSize to use fastio, combine dbcsname.c and name.c and pretty-fy the array, clean up some ugly formatting. Create context.c and move stream/file context routines there.
