e627b033dc Begin basic improvements to fwcontrol in the area of handling
video streams from cameras.

This patch changes the displayed timer to a time stamp and corrects
one or two mishandled errors.

072d350754 Increase buffer size of DV stream to prevent buffer
overrun caused by long blocking of file I/O (i.e. zfs).

77ee030b5f MFp4(simokawa_firewire):
Many internal structure changes for the FireWire driver.

- Compute CRC in CROM parsing.
- Add support for configuration ROM build.
- Simplify dummy buffer handling.
- busdma conversion
- Use swi_taskqueue_giant for -current.  Mark the interrupt routine as MPSAFE.
- AR buffer handling.
	Don't reallocate AR buffer but just recycle it.
	Don't malloc and copy per packet in fwohci_arcv().
	Pass packet to fw_rcv() using iovec.
	Application must prepare receiving buffer in advance.
- Change fw_bind API so that application should pre-allocate xfer structure.
- Add fw_xfer_unload() for recycling struct fw_xfer.
- Add post_busreset hook
- Remove unused 'sub' and 'act_type' in struct fw_xfer.
- Remove npacket from struct fw_bulkxfer.
- Don't call back handlers in fwochi_arcv() if the packet has
	not drained in AT queue
- Make firewire works on big endian platform.
- Use native endian for packet header and remove unnecessary ntohX/htonX.
- Remove FWXFERQ_PACKET mode.  We don't use it anymore.
- Remove unnecessary restriction of FWSTMAXCHUNK.
- Don't set root node for phy config packet if the root node is
	not cycle master capable but set myself for root node.
	We should be the root node after next bus reset.

- Improve self id handling

Tested on: i386, sparc64 and i386 with forced bounce buffer

2932d7d58b - Detect PAL by CIP header rather than the DSF bit in the DV header.
Some DVcam(ex. Panasonic NV-DS1 DV camcorder) doesn't seems to set
	this bit even if it's for PAL. Fix the DSF bit for such cases so that
	we can send back the stream to the DVcam without problem.
Problem Reported by: Richard Tobin <richard@cogsci.ed.ac.uk>

- Make the number of bulkxfer packets(NPACKET_T) and the number of packets
	write at once(TNBUF) to be different values.
	I observe some block noise for large TNBUF.
- Show the detection of NTSC or PAL.
- Pad with 0xff rather than 0x00 for broken frames.
- Bzero hdr[0].
- Remove unused code.

013490c5e0 - Search free device node to open. (fwcontrol.c)
- Exploit multiple packets read/write for DV stream. (fwdv.c)
- Add reference to libdv in the ports collection. (fwcontrol.8)
