Changed behavior of how we handle "NULL" summaries: just call
...
GRSimpleVals::EvalCal(), and don't change reference counts.
Remove "getDoNothingSummary()", as a NULL summary does the same thing.
Added temporary hack for the "Get" rule for objects that return a pointer type:
treat them as non-owned CF objects.
Added test case to detect the release of a non-owned object.

refactor Parser::ParseStructDeclaration to return a vector of uninterpreted
...
declarators. This allows the clients (C structs, objc classes, objc
properties, [future] C++ classes) etc, to do custom processing before invoking
an action.
This has two benefits in the short term:
1) objc ivar processing should be split out of ActOnField into its own ActOn method.
2) the new objc ivar action can take visibility info directly, eliminating
AllVisibilities in ParseObjCClassInstanceVariables.
3) objc properties can pass their own special sauce down to sema as well.

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.
