[PATCH v1] Configure Git contribution guidelines for github.com

[Lars Schneider <larsxschneider@gmail.com>]

Many open source projects use github.com for their contribution process.
Although we mirror the Git core repository to github.com [1] we do not
use any other github.com service. This is unknown/unexpected to a
number of (potential) contributors and consequently they create Pull
Requests against our mirror with their contributions. These Pull
Requests become stall [2]. This is frustrating to them as they think we
ignore them and it is also unsatisfactory for us as we miss potential
code improvements and/or new contributors.

GitHub offers a way to notify Pull Request contributors about the
contribution guidelines for a project [3]. Let's make use of this!

Hi,

I am perfectly aware that adding a ".github" directory in the Git core
tree is ugly. However, I believe the benefits ("well informed new
contributors") outweigh the injury.

You can see how a github.com Pull Request creation window would like here:
https://github.com/larsxschneider/git/compare/master...larsxschneider-patch-1?quick_pull=1

I added a link that jumps to a part my GitMerge 2017 talk which explains
Git core contributions from my point view. Although I tried my best, the
presentation is not perfect and might not reflect the view of the Git
community. I wouldn't have a problem at all with removing the link.

I also did not break the lines in the .github/*.md files as I thought it
renders nicer on the github.com web interface. I am happy to change that,
too, though.

Cheers,
Lars
