The QIOChannelBuffer's close implementation will free
the internal data buffer. It failed to reset the pointer
to NULL though, so when the object is later finalized
it will free it a second time with predictable crash.

The QIOChannelBuffer struct uses a 'char *' for its data
buffer. It will give simpler type compatibility with the
migration APIs if it uses 'uint8_t *' instead, avoiding
several casts.

Clean up includes so that osdep.h is included first and headers
which it implies are not included manually.

Add a QIOChannel subclass that is capable of performing I/O
to/from a memory buffer. This implementation does not attempt
to support concurrent readers & writers. It is designed for
serialized access where by a single thread at a time may write
data, seek and then read data back out.
