Turn 'SecuritySyntaxChecker' into a "meta" security checker for insecure APIs. Now
...
multiple checks are exposed as separate checkers, but CheckerManager only creates
one Checker object.

Rename AnalysisContext to AnalysisDeclContext. Not only is this name more accurate, but it frees up the name AnalysisContext for other uses.

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*.

[analyzer] Refactor PathDiagnosticLocation: Make PathDiagnosticLocation(SourceLocation...) private. Most of the effort here goes to making BugReport refer to a PathDiagnosticLocation instead of FullSourceLocation.
...
(Another step closer to the goal of having Diagnostics which can recover from invalid SourceLocations.)

Extend the ASTContext constructor to delay the initialization of
...
builtin types (When requested). This is another step toward making
ASTUnit build the ASTContext as needed when loading an AST file,
rather than doing so after the fact. No actual functionality change (yet).

Add security syntax checker for strcat() which causes the Static Analyzer to generate a warning any time the strcat() function is used with a note suggesting to use a function which provides bounded buffers. CWE-119.
...
Also, brings the security syntax checker more inline with coding standards.

Refactoring the security checker a little bit so that each CallExpr check doesn't get called for each CallExpr. Instead it does a switch and only runs the check for the proper identifier. Slight speed improvement (probably significant on very large ASTs), and should make it easier and more clear to add more checks for other CallExpr's later.

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...).
