There is no reason to expect this tool to be limited to C++11, it seems
very likely to be of on-going interest. It seems likely to be useful for
modernizing even as new libraries come out in TSes and other formats
than a complete standard. Fundamentally, we need something a bit more
general. After some discussion on the list, going with
'clang-modernize'.
I've tried to do a reasonably comprehensive job of fixing up the names,
but I may still have missed some. Feel free to poke me if you spot any
fallout here. Things I've tried reasonably hard to find and fix:
- cpp11-migrate -> clang-modernize
- Migrator -> Modernizer
- Clean up the introductory documentation that was C++11 specific.
I'll also point out that this tool continues to delight me. =] Also,
a huge thanks to those who have so carefully, thoroughly documented the
tool. The docs here are simply phenomenal. Every tool should be this
well documented. I hope I have updated the documentation reasonably
well, but I'm not very good at documentation, so review much
appreciated.

Re-commit of r189691 and r189689 now with a proper autoconf fix.
Massive simplification of how replacements and file overrides are
handled by the migrator:
* Sources and headers are all treated the same.
* All replacements for a given translation unit are stored in the same
TranslationUnitReplacements structure.
* Change tracking is updated only from main file; no need for
propagating "is tracking" flag around.
* Transform base class no longer responsible for applying replacements.
They are simply stored and main() looks after deduplication and
application.
* Renamed -yaml-only to -serialize-replacements. Same restrictions apply:
Can only request one transform. New restriction: formatting cannot also
be turned on since it's basically a transform.
* If -serialize-replacements is requested, changes to files will not be
applied on disk.
* Changed behaviour of function generating names for serialized
replacements: Only the main source file goes into the name of the file
since a file may contain changes for multiple different files.
* Updated HeaderReplacements LIT test for new serialization behaviour.
* Replaced old test that ensures replacements are not serialized if
-serialize-replacements is not provided. New version ensures changes
are made directly to all files in the translation unit.
* Updated unit tests.
* Due to major simplification of structures in FileOverrides.h, the
FileOverridesTest is quite a bit simpler now.

Revert "cpp11-migrate: Refactor for driver model of operation"
This reverts commit r189691.
This reverts commit r189689.
This was breaking the phase 1 OS X build for ~2 hours.
https://smooshbase.apple.com/buildbot-internal/builders/phase1%20-%20sanity/builds/9559
I reverted the latter commit since I think the latter depended on the former.

* Some file headers were missing for files in Core/
* Some headers were included but not necessary
* CMakeLists.txt was linking in LLVMSupport even though CMakeLists in subdirs
were linking it in too.
* StringRefisation of constructors of types in FileOverrides.h
* Other misc cleanups

Transforms will now make changes to headers if header modifications have been
enabled.
FIXME: Only UseNullptr contains a cursory header modification test. Other
transforms should have them too.

Summary:
Transform.* and Transforms.* moved to form a new library: libmigrateCore.
#includes updated to point to new header locations.
To support autoconf build, Cpp11Migrate.cpp moved to new subdirectory 'tool'
which also contains build files for creating final binary.
CMake and autoconf updated to build the new library and link it with
cpp11-migrate and with cpp11-migrate unit tests.
Dummy unit tests replaced with simple, but real, tests for Transform's public
interface.
TODO: Lib-ifying the transforms to further simplify build of cpp11-migrate.

For variable declarations initialized with new expressions, use 'auto' for the
type specifier.
The 'auto' replacement happens only when the type of the VarDecl exactly
matches the type of the initializer and the VarDecl is *not* CV-qualified. The
only case that is currently handled is if the pointer type of the VarDecl is
itself CV qualified.
Some improvements need to be made to Clang's TypeLoc information in order for
other CV qualifier cases to be successfully handled. See the new test suite
new_cv_failing.cpp for examples of usages that could be handled with such an
improvement.
Function pointers are, for now, not transformed until the identifier info can
be extracted.

The new Use-Auto transform replaces the type specifier for variable
declarations with the special C++11 'auto' type specifier. For now, the
replacement is done only for variables that are iterators of any of the
std containers and only if the type used is one of those explicitly
allowed by the standard (i.e. not an implementation-specific type).
