[bind10-dev] valgrind automation

[Jeremy C. Reed]

valgrind is automated on the CentOS system. It is valgrind-3.7.0.

Finally I have had five different banches successfully complete.  (I had 
automated around 160 runs of it and collected the outputted 
suppressions.)

The suppresions file I am using is at
/home/jreed/valgrind-suppressions.revisit

It is based on the 207 suppresssions I have at
/home/jreed/test-20120803/  which are one per file.

I learned that I can't have multiple suppressions for the same item even 
with wildcards because I think the later loaded one overrides earlier. 
(At least I didn't setup a unique name for each, so maybe that is why.) 
I also setup wildcards for common patterns and for actual source 
directory paths.

We will need to open tickets to handle existing ones.

Also should handle new reported failures by actually fixing the issue 
instead of masking with a new suppression configuration.
