parentpkt-line: eliminate the need for static buffer in packet_write_gently() (diff)

pkt-line: do not issue flush packets in write_packetized_*()
Remove the `packet_flush_gently()` call in `write_packetized_from_buf() and `write_packetized_from_fd()` and require the caller to call it if desired. Rename both functions to `write_packetized_from_*_no_flush()` to prevent later merge accidents. `write_packetized_from_buf()` currently only has one caller: `apply_multi_file_filter()` in `convert.c`. It always wants a flush packet to be written after writing the payload. However, we are about to introduce a caller that wants to write many packets before a final flush packet, so let's make the caller responsible for emitting the flush packet.
