a8461c0f3b tools/firewire: nosy-dump: work around segfault in decode_fcp
If I run "nosy-dump --view=transaction" with my camcorder on battery
instead of mains, it segfaults very quickly because of !t->request.
Perhaps this is because of increased likelyhood of incomplete
transactions (ack_busy when host writes to camcorder's FCP_Request)
and a bug deeper in nosy-dump's transaction housekeeping.  This is a
quick workaround to get me going.

1bcc69fb6a tools/firewire: nosy-dump: fix it on x86-64
Replace 'unsigned long' and the (unaffected) 'unsigned int' by uint32_t
if they represent quadlets.

9f6d3c4b76 tools/firewire: add userspace front-end of nosy
This adds nosy-dump, the userspace part of nosy, the IEEE 1394 traffic
sniffer for Texas Instruments PCILynx/ PCILynx2 based cards.  Author is
Kristian Høgsberg.

The files added here are taken from
git://anongit.freedesktop.org/~krh/nosy commit ee29be97 (2009-11-10)
with the following changes by Stefan Richter:
  - Parts pertaining to the kernel module removed from Makefile.
  - dist target removed from the Makefile.
  - Mentioned nosy-dump in the Kconfig help to nosy's kernel component.
  - Add copyright notice to nosy-dump.c.  This is a duplicate of the
    respective notice in the kernel component nosy.c except for a time
    span of 2002 - 2006, according to Kristian's git log.
