Refactored most of the "Store" piece of ValueState into a Store type. The
...
current store implementation is now encapsulated by BasicStore.
These changes prompted some long due constification of ValueState. Much of the
diffs in this patch include adding "const" qualifiers.

Generalize caching mechanism for bugs reports. Now individual BugTypes

can decide the policy on how to cache related bugs. This allows us to
properly to handle warning about multiple leaks in the same location in the
ref count checker (not yet done).

Simplified internal logic of BugReporter, consolidating EmitWarning and

EmitPathWarning into one method. We now properly handle emitting warnings
without a PathDiagnosticClient when the warning does not involve a particular

Fixed regressions in error reporting due to copy-paste errors (using the "begin"

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.

Added skeleton checking for NSString's method initWithFormat: (do not pass nil). This won't be useful in most cases right now
...
because the analyzer isn't tracking expected types for an object, and [NSString alloc] just runs "id".
