#2 script to summarize unfreed report

[Bruce Hoult]

I find that LEAKTABLE gives far too little information, but
SHOWUNFREED gives far too much!

So I wrote this script to summarize the output from
SHOWUNFREED.

It collapses each unique allocation site (backtrace)
into a single entry, with a new summary line showing
how many times it leaked, and the amount of memory leaked.
