[PATCH udev] rules: add more FireWire IDs: Point Grey IIDC; AV/C +

[Stefan Richter <stefanr@s5r6.in-berlin.de>]

1. IIDC cameras from Point Grey use the vendor OUI as Specifier_ID
instead of the 1394 TA's OUI but are otherwise fully compliant to the
IIDC spec. Their device files should be accessible like those of any
other IIDC cameras.

2. Originally, the Software_Version of devices that implement FCP
(IEC 61883-1 Function Control Protocol) was meant to be a bitmap of all
command sets that an FCP capable unit supports.  Bitmap flags are
defined for AV/C, CAL, EHS, HAVi, and vendor unique command sets.
Software_Version was revised to be a simple identifier instead, and
devices that support several command sets were meant to instantiate one
unit directory for each command set.  Still, some devices with the flags
for AV/C and vendor unique command sets combined were released (but
apparently no devices with any other flag combinations).  These rare but
existing AV/C + vendor unique devices need to be accessible just like
plain AV/C devices.

Side notes:
 - Many AV/C devices make use of the Vendor Dependent AV/C command, but
this is unrelated to vendor unique FCP command sets.
 - Here are all standardized FireWire protocol identifiers that I know
of, listed as Specifier_ID:Software_Version | specifier | protocol.
0x00005e:0x000001 | IANA    | IPv4 over 1394 (RFC 2734)
0x00005e:0x000002 | IANA    | IPv6 over 1394 (RFC 3146)
0x00609e:0x010483 | INCITS  | SBP-2 (or SCSI command sets over SBP-3)
0x00609e:0x0105bb | INCITS  | AV/C over SBP-3
0x00a02d:0x010001 | 1394 TA | AV/C (over FCP)
0x00a02d:0x010002 | 1394 TA | CAL
0x00a02d:0x010004 | 1394 TA | EHS
0x00a02d:0x010008 | 1394 TA | HAVi
0x00a02d:0x014000 | 1394 TA | Vendor Unique
0x00a02d:0x014001 | 1394 TA | Vendor Unique and AV/C (over FCP)
0x00a02d:0x000100 | 1394 TA | IIDC 1.04
0x00a02d:0x000101 | 1394 TA | IIDC 1.20
0x00a02d:0x000102 | 1394 TA | IIDC 1.30
0x00a02d:0x0A6BE2 | 1394 TA | DPP 1.0
0x00a02d:0x4B661F | 1394 TA | IICP 1.0
For now we are only interested in udev rules for AV/C and IIDC.
