Subject: pkt-line: add packet_write function

pkt-line: add packet_write function

Add a function which can be used to write the contents of an arbitrary
buffer.  This makes it easy to build up data in a buffer before writing
the packet instead of formatting the entire contents of the packet using
'packet_write_fmt()'.
