Contains unfinished attempt to integrate IWYU (ref #549). To finish it different job should be done, specifically: - Instead of feeding IWYU with modified file a mirror source tree should be created with the help of CMake which will contain modified sources. This solves the problem with IWYU thinking that `*.generated.h` headers should be included in place of `*` headers. - Build IWYU as all other third-party utilities. - Make modified sources avoid problems with `nvim/func_attr.h` includes and various related tricks. Current script may only be used for manual checks like this: ./scripts/check-includes.py \ --generated-includes-dir build/include \ --generated-includes-dir build/src/nvim/auto \ --file src/nvim/eval/typval.c \ -- -Isrc -Ibuild/include -Ibuild/src/nvim/auto \ -DINCLUDE_GENERATED_DECLARATIONS (it is also somewhat fine with `--file src/nvim/eval/typval.h`). I have no idea why (I mean, why developer think that these lines are needed, why they are suggested is pretty obvious: because there is typedef which mentions them before structs are defined), but for typval.h it reports, among other things, that it should add lines struct dictvar_S; struct listitem_S; struct listvar_S; struct listwatch_S;
