compat-wireless: add linux-next-pending, crap patch dirs and nagometer

Sometimes you have no other option but to carry around patches.
This can happen for a variety of reasons. Ultimately testing of code
cannot happen on the kernel maintainer's clock but on your own.

This expands the idea of the linux-next-cherry-pick patch directory
on compat-wireless to also allow for patches to be merged which are
posted to some mailing list but pending merge due to some reasons
(merge window is a good example). It also adds a crap patch directory
for those really nasty situations you can run into where you have
no other option but to give someone a release with some delta even
if the patch is not yet posted anywhere.

The focus should always be upstream though so to avoid these
situations we will also provide code metrics to indicate to
the package maintainer how much code came from each directory,
including the backport code to support older kernel releases.

Maybe we should add the code-metrics.txt file as a print out
on the compat module load :)
