[RFC PATCH] Script for generating Documentation/dontdiff from .gitignore files.

[Eduard - Gabriel Munteanu]

.gitignore files get more testing than Documentation/dontdiff, since most
developers follow Git workflow when sending patches. The latter tends to
stay outdated and needs to be synchronized every now and then. This patch
provides a script that scans all .gitignore files and generates a
Documentation/dontdiff to stdout.
