Fixed non-standard behaviour of rdwr streams

Originally had two seperate positions for reading/writing,
but this is inconsistent with the the posix standard, which
has a single position for reading and writing.

Also added proper handling of when the file is dirty, just
added an internal flag for this state.

Also moved the entry out of the file struct, and rearranged
some members to clean things up.
