This implements asynchronous streams on juju, i.e. enables
raw1394_async_stream() and raw1394_start_async_stream() to work
with the new firewire kernel stack.

This allows raw1394_bandwidth_modify() and raw1394_channel_modify()
to work on juju without write access to the IRM's character device file.
If either the build-time requirement of firewire-cdev header ABI >= v.2
or the runtime requirement of firewire-core ABI >= v.2 is not satisfied,
the code falls back to transactions to the IRM as before.

because they do the same.
We only may want a separate fw_bandwidth_modify() in the future when
firewire-core gains a special ioctl() for that.
(Not runtime-tested, but it looks good to me.)

(juju)
Reported by Adrian Knoth: fw_channel_modify() was unable to allocate
some channels which were actually free.

This can be easily fixed by replacing fw_channel_modify() by
ieee1394_channel_modify() because this is highlevel enough to work with
Juju as well. We only may want a separate fw_channel_modify() in the
future when firewire-core gains a special ioctl() for that.
Also fix a documentation typo: raw1394_channel_modify() did not show up
in extracted API documentation due to a cut'n'paste typo in raw1394.h.

The ieee1394 version of raw1394_read_cycle_timer() fell over the cliff
in "First cut at integrating juju". This brings it back and adds a juju
version of it.
Also correct a typo in the inline documentation: s/get/read/
