This adds debug printks for asynchronous transmission and reception and
for self ID reception. They can be enabled at module load time, and at
runtime via /sys/module/firewire_ohci/parameters/debug.

Also added: Logging of interrupt event codes and of cancelled AT
packets.
The code now depends on a Kconfig variable. This makes it easier to
build firewire-ohci without the feature or to make it an option in the
future. The variable is currently hidden and always on.
This feature inflates firewire-ohci.ko by 7 kB = 27% on x86-64 and by
4 kB = 23% on i686.

Remove some less necessary information, point out that video1394 and
dv1394 should be blacklisted along with ohci1394.

Alas that won't work so good, because nobody reads help texts.
I thought about adding some crude multiple choice selection (build the
old stack, build the new stack, build both stacks). It's possible, but
it would introduce awkward dummy config variables.

Of course everybody immediately associates "fw-" with FireWire, not
firmware or firewall or whatever. But "firewire-" has a nice ring to
it too.

With the CRC ITU-T implementation available in lib/ we can use that instead.
This also fixes a bug in the topology map crc computation.
