Subject: [RFC PATCH v6 1/1] scripts: Introduce a default git.orderFile

When reviewing patches, it looks much nicer to have some changes shown
before others, which allow better understanding of the patch before the
the .c files reviewing.

Introduce a default git.orderFile, in order to help developers getting the
best ordering easier.

Changes since RFCv5:
- Replace "*Kconfig*" by "Kconfig*" + "*/Kconfig*" to avoid matching files
  like foo-Kconfig, which should not be valid here.
- Same of above for "*Kbuild*" and "*Makefile*"
- Thanks Masahiro Yamada for this suggestion!

Changes since RFCv4:
- Added scripts/* into "build system" section
- Added "git-specific" section with this script and .gitignore
- Thanks for this feedback Nicolas!

Changes since RFCv3:
- Added "*types.h" matching so type headers appear before regular headers
- Removed line ends ($) in patterns: they previously provided a
  false-positive
- Fixed build patterns to allow matching Kconfig, Kbuild & Makefile
  in any subdirectory

Changes since RFCv2:
- Fixed licence comment to from /**/ to #
- Fixed filename in how-to comment
- Fix build order: Kconfig -> Kbuild -> Makefile
- Add *.mk extension
- Add line-ends ($) to make sure and get the correct extensions
- Thanks Masahiro Yamada for above suggestions!
- 1 Ack, thanks Randy!

Changes since RFCv1:
- Added Kconfig* (thanks Randy Dunlap!)
- Changed Kbuild to Kbuild* (improve matching)
