[Crash-utility] About the comments

[Hu Keping]

hi there,

I'm a freshman to CRASH, I want to make some contribute for it as I
found it very usefull, especially with Kdump.

But i run to a little trouble when i read the source code of it for
there is not enough comments for some critical data structures say,
struct syment, struct bt_info, etc.

I would really appreciate it if there would be some progress on that.

Thanks.
