Rebuild dependent AUR Packages

[L0ric0]

It would be nice if pkgbuilder could search for installed aur packages that are dependent on the upgraded packages (also aur packages avoiding cycles) and rebuild them to avoid having broken aur packages installed.

[L0ric0]

possible flow would be:

1. after installation return list of installed pkgs
2. search for dependent aur-pkgs not in cache
3. build and install dependent aur-pkgs and cache them
4. repeat from 2

I would like to implement it but I don't realy know at which point in the code
