- removed PrelPosix.c_read, PrelPosix.c_write
- added Ptr and RawBuffer versions of PrelHandle.write_off,
  and PrelHandle.read_off and exported them, i.e., PrelHandle
  now exports:

    read_off_ba :: FD -> Bool -> RawBuffer -> Int -> CInt -> IO CInt
    read_off :: FD -> Bool -> Ptr CChar -> Int -> CInt -> IO CInt
    write_off_ba :: CInt -> Bool -> RawBuffer -> Int -> CInt -> IO CInt
    write_off :: CInt -> Bool -> Ptr CChar -> Int -> CInt -> IO CInt

- make hPutChar (win)socket friendly.
