Making progress with introduction of unit tests to Uboot

The old uboot code had, amazingly enough, 21k lines of unit tests. But they were not useful unit tests, as one had to run each program individually, and they each had a bunch of (different) prerequisites, such as account_id 3 existing and having an empty inbox, and so on. And with the older tests, their output would be a bunch of print statements (e.g. insert message; print count of messages), and one would have to compare the printed output with the expected results (which weren't documented anywhere).

I am converting them to PerlUnit (which is a clone of JUnit) so that we can automatically and easily run as many tests as possible before each release. This is an incredibly productive task, as I don't even need to write new unit tests (and think about testing strategy), I'm just converting the lines to a format enabling them to be convenient to run!

So far 3.6k lines in 86 test functions in 33 test classes :)

$ ./test.pl

Time: 48 wallclock secs ( 8.65 usr  0.56 sys +  0.02 cusr  0.25 csys =  9.48 CPU)

OK (86 tests)
