I have some issues with your excessive use of new C++11 features, I think they are often not idiomatic. please clean this code up a bit and strive for easy-to-read, documented code. while you are of course free to use new C++11 code, it is not meant as a playground where you should use every new feature just because its new.</p></pre>

We are going to link this library into kdev-clang, depending on situation it may be very simple interface to the whole stuff. I'm not sure about future of this file, for now i will leave details about binary compatibility and simply focus on interface. And "in case" - we will have less work to make this binary separation.</p></pre>

Skeleton of interface for KDevelop.
Build system (really nasty, linked DSO has 18MiB).
CompilationDatabase for CMake projects and ClangTool (with cache, but without cache updates).
Interface is not frozen for now.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Currently building of refactorings is enabled only if Clang 3.6.x is found. In other case build system behaves exactly as current master.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Refactorings require some contextual informations about projects. I made draft of interface with should feature:
- Stable ABI - dlopen (or equivalent) a DSO and if succeed (binary is still compatible with Clang libraries ABI), dlsym (or equivalent) some functions which are to provide all refactorings features
- Prototypes (with some implementation) of functions constituting API between KDevelop and refactorings backend
- It may be considered to use Qt plugin system to provide implementation of this (or equivalent) interface. This would be more expensive, but also more portable
- In worst case this library (static version) can be used with additional driver to make stand-alone executable providing all refactorings features (but it would require additional marshaling and hamper cooperation with user (how to provide UI in such a case?))</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Handling dependencies between Clang/LLVM libraries is a nightmare. I extended FindClang.cmake to find much more libraries and used them to link with first pieces of my code. This is huge, requires additional libraries like zlib and even ordering of dependencies can cause linker errors.</p>
