From: Lars Schneider <larsxschneider@xxxxxxxxx>
packet_write_fmt_gently() uses format_packet() which lets the caller
only send string data via "%s". That means it cannot be used for
arbitrary data that may contain NULs.
Add packet_write_gently() which writes arbitrary data and returns `0`
for success and `-1` for an error. This function is used by other
pkt-line functions in a subsequent patch.
