Record revisions of documents in macro definitions and usages. Then,
when searching for usages, check the revision of the documents against
the revision of the macros. If they are out-of-sync, repreprocess the
documents to get up-to-date info.

This rewrite fixes a couple of issues with the pre-processor. It now
supports:
- macros in macro bodies
- stringification of parameters [cpp.stringize]
- the concatenation operator [cpp.concat]
- #include MACRO_HERE
- defined() inside macro bodies used in pp-conditions.

It's now possible to get the macro definition with the actual
line breaks used on the code. This is particularly useful for
tooltips in order for them to look nice.
The preprocessor is changed so the macro also stores the breaks
positions. This doesn't seem to have any impact on performance.
In my machine, for example, the total time for parsing Creator's
source code is approx. 18100ms with or without the patch.

In preparation for finding macro uses.
* Macro: add offset and length
* MacroUse: add line
* Document: add convenience functions for finding a macro definition, use
or undefined use at a given location.

Things you mustn't do:
1) end an enum with a comma
2) #include <cxxxx> and not use std::
3) use anonymous structures
All three things are invalid C++. Anonymous structures inside
anonymous unions are allowed by GCC, but that doesn't mean it's valid.
