Nick Mathewson 32b9edeb91 Fix build warnings from Coverity related to our BUG macro

In the Linux kernel, the BUG() macro causes an instant panic.  Our
BUG() macro is different, however: it generates a nonfatal assertion
failure, and is usable as an expression.

Additionally, this patch tells util_bug.h to make all assertion
failures into fatal conditions when we're building with a static
analysis tool, so that the analysis tool can look for instances
where they're reachable.

Fixes bug 23030.

Raw Blame History

   o Minor bugfixes (coverity builds):
     - Avoid Coverity build warnings related to our BUG() macro. By
       default, Coverity treats BUG() as the Linux kernel does: an
       instant abort(). We need to override that so our BUG() macro
       doesn't prevent Coverity from analyzing functions that use it.
       Fixes bug 23030; bugfix on 0.2.9.1-alpha.
