Coverity Scans Revived

[Amine Khaldi]

Hello folks,

Recently we (myself and Urias from Haiku) have been working on getting 
the coverity scans up and running again. I'm happy to announce that we 
succeeded ! :)

I submitted a scan and the results are up online. I'll submit further 
scans when necessary, like it's already done with clang analyzer scans.

Have fun !

Regards,
Amine.
