libfuse: support zero copy writes in lowlevel interface
Add new ->write_buf() method to low level interface. This
allows passig a generic buffer, either containing a memory buffer
or a file descriptor. This allows implementing zero copy writes.
Add fuse_session_receive_buf() and fuse_session_process_buf()
which may be used in event loop implementations to replace
fuse_chan_recv() and fuse_session_process() respectively.
