2016-05-26io: avoid double-free when closing QIOChannelBufferDaniel P. Berrange
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.

2016-02-15io: convert QIOChannelBuffer to use uint8_t instead of charDaniel P. Berrange
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. Signed-off-by: Daniel P. Berrange <berrange@redhat.com>

2015-12-18io: add QIOChannelBuffer classDaniel P. Berrange
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. Signed-off-by: Daniel P. Berrange <berrange@redhat.com>
