This should reduce use-after-free errors and accidental close via create or
remove. This change includes one functional fix as well: when closing via
remove, the closed field was not set and the finalizer was not freed, so the
file would have been clunked at some random point in the future.

The message size check is legitimate: the size must be negotiated, which
relies on the fixed message limit up front. Sending a message larger than
that indicates that the connection is out of sync and is considered a
socket error (disconnect).
Similarly, sending a size that is too small indicates that the stream is
out-of-sync or invalid.

We have been unnecessarily creating too many savable types implicitly.

Fun fact: in protocol version negotiation, our 9p version must be
written "9P2000.L". In the 'version' mount option, it must be
written "9p2000.L". Very consistent!
The mount command as given complains about an unknown protocol
version. Drop it entirely because Linux defaults to 9p2000.L
anyways.
