[cfe-commits] PthreadLock Checker enhancements

[Rui Paulo]

Hi,

The following patch is what I've been working on for the last couple weeks. It seems to fit it's initial purpose fine, that is, to find simple locking problems. It tries to find double locks and some lock order reversals. Although there's room for improvement, I would like to see this committed after review.
This patch includes a test case for the newly introduced checks as well.

Regards,
