[OpenAFS-port-darwin] requests for "small" tasks

[Derrick J Brashear]

If anyone is bored and has time to poke at a few things,

1) a script to create a backtrace from a panic log. it needs to, at least:
a) parse the panic log and pull out the module address of afs and the 
"backtrace" addresses
b) kextload -n with the address extracted in a to create the symbol file
c) invoke gdb adding the symbol file, set print asm-demangle on, and then 
x/i each of the "backtrace" addresses

2) modify the buildpkg script in 1.4.5pre2 or from CVS to create a dmg of 
the kext dSYM directory that we can ship as OpenAFSDebugKit

3) installer.app plugin to accept a cellname and set it in ThisCell. if 
you want to be fancy you can do more, and i will happily talk with you 
about what.
