[analyzer] Simplify CheckerContext
...
Remove dead members/parameters: ProgramState, respondsToCallback, autoTransition.
Remove addTransition method since it's the same as generateNode. Maybe we should
rename generateNode to genTransition (since a transition is always automatically
generated)?

[analyze] Convert EndOfPath callback to use CheckerContext
...
Get rid of the EndOfPathBuilder completely.
Use the generic NodeBuilder to generate nodes.
Enqueue the end of path frontier explicitly.

Change operator<< for raw_ostream and NamedDecl to take a reference instead of a pointer.
...
Passing a pointer was a bad idea as it collides with the overload for void*.

If size was equal to 0, either NULL or a pointer suitable to be passed to
...
free() is returned by realloc(). Most code expect NULL.
And we only need to transfer one final ProgramState.

Remove EnhancedBugReport and RangedBugReport - pull all the extra functionality they provided into their parent BugReport. The only functional changes are: made getRanges() non const - it adds default range to Ranges if none are supplied, made getStmt() private, which was another FIXME.

Cleanup various declarations of 'Stmt*' to be 'Stmt *', etc. in libAnalyzer and libStaticAnalyzer[*]. It was highly inconsistent, and very ugly to look at.

More accurately model realloc() when the size argument is 0. realloc() with a size of 0 is equivalent to free(). The memory region should be marked as free and not used again.

Unit tests f2_realloc_0(), f6_realloc(), and f7_realloc() contributed by Marshall Clow <mclow.lists@gmail.com>. Thanks!

[analyzer] Refactor EndOfFunctionNodeBuilder.
...
-Introduce EndOfFunctionNodeBuilder::withCheckerTag to allow it be "specialized" with a
checker tag and not require the checkers to pass a tag.
-For EndOfFunctionNodeBuilder::generateNode, reverse the order of tag/P parameters since
there are actual calls that assume the second parameter is ExplodedNode.

Chris Lattner has strong opinions about directory

layout. :)
Rename the 'EntoSA' directories to 'StaticAnalyzer'.
Internally we will still use the 'ento' namespace
for the analyzer engine (unless there are further
sabre rattlings...).
