Ted Kremenek 7acc3a36ef Major refactoring/cleanup of GRExprEngine, ExplodedGraph, and BugReporter. 
Bugs are now reported using a combination of "BugType" (previously
BugDescription) and Bug "BugReport" objects, which are fed to BugReporter (which
generates PathDiagnostics). This provides a far more modular way of registering
bug types and plugging in diagnostics.

GRExprEngine now owns its copy of GRCoreEngine, and is not owned by the
ExplodedGraph.

ExplodedGraph is no longer templated on the "checker", but instead on the state
contained in the nodes.

Ted Kremenek 3cef454e2e Added new "BugReporterHelper" class which is used by BugReporter to emit 
checker-specific diagnostics.

Ted Kremenek 89575b7bcb Use "getRanges" in default implementation of "getEndPath" to determine 
the ranges of highlighted elements in the source code.

Ted Kremenek cb2dc8eca5 Hooked up GRSimpleAPICheck and the simple Objective-C Foundation checks to use 
the new BugReporter interface.

Ted Kremenek 4e9cc3f272 When creating PathDiagnostics, created a trimmed graph first and report the 
BFS path to the root.  This also avoids problems with loops in the ExplodedGraph.

Ted Kremenek 505a36afc6 Created new path-sensitive bug-reporting scheme based on the classes 
"BugReporter" and "BugDescription".  BugDescription is used to describe
a bug and provide pieces of the PathDiagnostic, and BugReporter creates
the actual PathDiagnostic by crawling through the ExplodedGraph.

Migrated checks done by GRSimpleVals to be reported using the new BugReporter
mechanism.
