[PATCH] IDE: support QT Creator

[Alexey Dobriyan]

Add little script to generate QT Creator project files, so that parsing
and navigating codebase mostly works.

The important part is to run 'make prepare' before opening project
so that generated headers are picked up and clone&fixup coding style
in the editor to match kernel coding style.

Then run

	$ ./scripts/ide/qt-creator.sh xxx

from top-level directory

Note:
ibmvnic.c is excluded from project files to workaround libCPlusPlus crash.
