io: add QIOChannelBuffer class
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>
