[mythtv] firewire tester

[Jim Westfall]

Hi

Attached is a firewire tester I wrote up this evening.  I would like to 
get a few firewire folks to give it a try.  It still needs a bit of clean 
up, but should be mostly functional.

It allows testing of both p2p and broadcast connections, as well as 
attempting to fix up broadcast connections.

should make testing easier then the test-mpeg2 > blah, ctrl-c, ls -l blah 
method.

firewire_tester <action> -n <node> [-P <port>] [-v]
 Actions: (one is required)
    -b          - test broadcast connection
    -p          - test p2p connection
    -B          - attempt to fix/stabilize broadcast connection
 Options
    -n <node>   - required
    -P <port>   - default 0
    -v          - verbose


$ ./firewire_tester -p -n 2 
Testing P2P connection, node 2, channel 2
p2p: failed

$ ./firewire_tester -b -n 2 
Testing broadcast connection, node 2, channel 61
broadcast: failed

$ ./firewire_tester -B -n 2 
Attempting to fixup broadcast connection on node 2
