devtools: add script to find duplicated includes

Browse Source 
Based on Stephen's idea (originally implemented in a Perl script),
this is a shell script to find duplicated includes in a file.
It looks for all the .c and .h files of the git repository.

It is fast enough because automatically well parallelized.
