* append_file()
*
* Opens the file "filename" for reading. Parses the FLV header and checks
* everything looks normal. Then reads FLV data packets from the file
* continuously in a loop until no more data can be read from the file.
* The header of each FLV packet is parsed and the various fields stored in an
* FLVpacket struct. Non-video or audio packets (e.g. metadata packets) are
* skipped over and not parsed any further than the header. Video and audio
* packets have their data payload and closing back pointer also stored in
* memory.
* If the starting timestamp for the current output file has already been
* determined, write_packet() is then called to write the packet to the output
* file. Otherwise the packets are buffered using buffer_packet() until the
* first video packet has been read from the input file. The starting timestamp
* is calculated based on the timestamp of the first video packet, the
* video framerate, and the timestamp of the last video packet read from the
* previous input file. The packet buffer is then flushed and operation
* reverts to simply reading packets from input and writing to output.
* When no more data can be read from the input file, it is closed and the
* function returns.
