diagnostic callback mechanism, so all diagnostics now go through that
callback. Also, eliminate the displayDiagnostics flag to
clang_createIndex(), since it is no longer necessary: the client
determines whether to display diagnostics or not.

clients can format diagnostics as they wish rather than having to
parse standard error. All of the important parts of the front end's
diagnostics are exposed: text, severity, location, source ranges, and
fix-its. The diagnostics callback is now available with
clang_createTranslationUnitFromSource() and
clang_createTranslationUnit().
As part of this change, CXSourceLocation and CXSourceRange got one
pointer larger, since we need to hold on to the SourceManager and
LangOptions structures in the source location. This is the minimum
amount of information needed for the functions that operate on source
locations and ranges (as implemented now). Previously we held on to
the ASTContext, but the diagnostics callback can end up with source
locations when there is no ASTContext (or preprocessor).
Still to do:
- Code completion needs to support the diagnostics callback, once we
have the ability to (de-)serialize diagnostics.
- Eliminate the "displayDiagnostics" argument to createIndex; we'll
always pass diagnostics to the callback and let it deal with display.

strings than what we currently have in Sema. This is both an
experiment and a WIP.
The idea is simple: parse the format string incrementally,
constructing a well-structure representation of each format specifier.
Each format specifier is then handed back one-by-one to a client via a
callback. Malformed format strings are also handled with callbacks.
The idea is to separate the parsing of the format string from the
emission of diagnostics. Currently what we have in Sema for handling
format strings is a mongrel of both that is hard to follow and
difficult to modify (I can apply this label since I'm the original
author of that code).
This is in libAnalysis as it is reasonable generic and can potentially
be used both by libSema and libChecker.
Comments welcome.

reusable and modular API pieces.
Start by pulling the logic for deriving the Cocoa naming convention
into a separate API, header, and source file.

(1) libAnalysis is a generic analysis library that can be used by
Sema. It defines the CFG, basic dataflow analysis primitives, and
inexpensive flow-sensitive analyses (e.g. LiveVariables).
(2) libChecker contains the guts of the static analyzer, incuding the
path-sensitive analysis engine and domain-specific checks.
Now any clients that want to use the frontend to build their own tools
don't need to link in the entire static analyzer.
This change exposes various obvious cleanups that can be made to the
layout of files and headers in libChecker. More changes pending. :)
This change also exposed a layering violation between AnalysisContext
and MemRegion. BlockInvocationContext shouldn't explicitly know about
BlockDataRegions. For now I've removed the BlockDataRegion* from
BlockInvocationContext (removing context-sensitivity; although this
wasn't used yet). We need to have a better way to extend
BlockInvocationContext (and any LocationContext) to add
context-sensitivty.

codegen it, so we get 'cannot compile this builtin function yet'
errors, just like we do currently for __builtin_isinf. However,
this should let us parse headers that use it without barfing,
which should help PR6083.
